How to secure comfort for users in a modern building? Nowadays the buildings are equipped with integrated systems of: aircondition, lighting, fire signalization, alarm, access control and many others. It will not dispense with either a computer network or telephones. A computer system watches over suitable work of all important components of the building. It is important to foresee structural wiring location as early as in the stage of designing. It will make possible “intelligent” controlling and managing all installed systems in the building. It will be also a basis to ICT systems functioning which secures a comfortable access either to Internet or Intranet for all users. It is also possible to provide a dedicated power supply for computer equipment that guarantees reliability. Thanks to correct working of all installed systems in the “intelligent” building, it is possible to work effictively using the ICT systems. Costs of the building maintenance are always under control because the computer system limits heating or switches off lights automatically when nobody is in supervised rooms, for example: on free days.

Is it possible to work in an office without: computer network, access to Internet or electronic secure systems? Today it does not have to mean troubles with these devices managing or operating. Everything is controlled and operated by computer systems of the “intelligent” office.The main functions realized in the “intelligent” office are: control of lighting, heating, ventilation, aircondition and computer or wirings. The whole managing is remote – controlled, obtaining information about work of entire building infrastructure. Thanks to all building systems integration, they can be managed collectively or individually, which depends on requirements. It decreases the costs and improves functionality of the office. Managing the building systems lets rationalize their work, gaining measurable economical effects. Think about removing to the “intelligent” office off XXIth century today. Forget about troubles connected with managing and operating systems or installations of a building. Let the computer system help you out wherever it is possible.

In halls, objects and warehouses the most important is to guarantee safety and effectivity. In gaining it, help computer systems that guarantee the maximal level of security and comfort for people staying in -them.
Teleinformatic and wirings used in that kind of buildings have to be suitably selected. Halls and industrial objects are a specific environment from variety and conductig teletechnic installations point of view. Difficult environmental conditions and technological requirementst have peculiar influence on materials and technologies used in their installation. The crucial part in the industrial objects play security systems such as: alarm system, detecting and extinguishing system and access control. It is necessary to made them in the way that they could be able to guarantee the maximal level of safety and comfort for those who work in them, and to meet all required conditions for technological processes. The knowledge and skills of concractor may pay dividents in a production hall or warehouse and no matter whether they are small or big. Let all industrial objects be safe and friendly for workers.

Don’t you thrill thinking about losing important data of your company. Information is the most precious commodity, so it is worth keeping. A checked solution used by the far – sighted is a Data Center. The Data Center consists of a few separate objects or their parts, in which there are centers responsible for sending, processing and keeping data. Centers of collecting data have surface from hundreds to thousands square meters and they are equipped with a comprehensive technical and computer infrastructure. Designing a safe Data Center is a process that requires specialistic knowledge and experience. Today special attention is paid to systems of: power supply, data transmission, security and cooling. The Data Center has to guarantee the highest level of security and safety and let computer and telecommunications systems develop without any risk connected with data security.

Have you got servers in your building? If not, then think: where can you place important essential for computer network and telecommunications devices such as:servers, data backup devices, routers, switches, UPSes, telephone exchangers and many others? There is no safer place than a special prepared room where there is a central local teleinformatic system junction. The room ought to be equipped with wireless power supply ( UPS ), ventilation, aircondition and suitable system of fire signalisation and extinguishing. An essential component is registering and access control, for example: with making use of video cameras (the screen can be negative ). Where there are servers one finds a lot of wires that are gathered in crossover and conducting cabinets or electric distributors. In a special designed room it is easier to organise cable routes, for example by installing lifting floors. Well prepared and organised room is a clue to efficient work of ICT systems installed in a building. If you want to have efficient and safe network, think about a serevers room.

Solutions for so called "e-business" secure competitive adventage for companies. Only because it is possible to run a non stop open Internet shop, where one can buy unlimited number of good. At the same time a lot of buyers can be serviced. In contacts between two companies ( B2B ) an adventage of solutions connected with electronic business is, for example: automatic gathering contracting parties’ orders which lets limit warehouse reserves. How to use this wide range of new possibilities? What you need is a suitable teleinformatic infrastructure. In case of running an internet busines it is necessarily to secure faultless work for transactional systems. Designers and contractors of teleinformatic infrastructure that supports electronic trade have to work out correctly all protections for trouble spot elements of the system. Offering sale through Internet warehouses can be transfered out of the city, where the cost of renting rooms is lower. Staff is needless while the Internet shop is open all the time. Moreover internet trade is one of the fastest developing branch of Internet.

A modern housing estate is a well designed system of lighting and power supply, a telephone installation, a homephone or a videophone, a fire system or alerm with 24h monitoring, cable TV and a constant access to Internet. It is worth introducing a people’s access system and car entrance system. It is sure that in a few years every housing estate will be equipped with own computer network. Presently, there considered new solutions such as retning films through local networks or remote – control of household devices by using a WWW browser. Even if it is a future it is worth being well prepared. So that all mentioned systems could work, suitable designed and installed installations are needed. All these solutions are possible thanks to fast development of digital technology and companies that can install them in blocks of flats.

A fundamental role of a housing estste network is enabling all users to have an access to Internet. They can be used to exchange information between occupants, too. On the beginning of XXIth century an access to a local computer network is becoming a standart equipment of a flat. From a technical point of view, there ane not any limits for occupants of every estate to be pleased with a full access to a computer network and Internet. A construction of the housing estate network consists on preparing and equipping a central junction of the network with suitable devices and wiring a building or an estate. Each flat is supplied of a wire, through which data will be transferred to a computer, and the junction is connected to Internet. After configuring computers each occupant will have a fast and confortable access to Internet. Additionally, the network junction can be equipped with a server that makes possible using many others services.

Internet, an e-mail are the terms we meet every day in an office. It is rather difficult to imagine an office without an informatic network and connected to it computers. LAN range include a small area workstations, servers, printers and other devices used in an office that are connected with each other. LAN can be installed in a house, an housing estate, an office or an industrial plant and it can include one or a few buildings. A local network let many users use the same devices and applications, thus for example instead of installing small prinders to each computer it is possible to make available one fast and effective device. This solution is cheaper and better. If a local network is to work correctly, it has to be well designed with taking into considerations needs and a guarantee of future extension. LANs have to guarantee high capacity, reliabality and calibration. Wiring system, power supply and softwere configuration ought to be carried out professionally. Today, it is not a point whether to have LAN or not, but whether is it to be fast, efficient and modern or not.

If a companty has a few banches equipped with LAN, thus connecting them by WAN seems to be obvious. An access to WAN is usually gained by using service providers’ resources, offering own informatic infrastructures. Connections with WAN can be realized by copper joints, optical fibers, radio and satelite joints. Using suitable technologies guarantees a safe data transmission, allows to virtual making available some network resources to a service provider and a defined user. Not only does in that way configured network let data transmission, but it allows also to send audio and video which is important during video conferences. WAN allows to have an access to common applications, e-mail servers and it makes remote work possible. The solution facilitates an effecting resources managing in all company, independantly from its branches localisation what lets gathering sale information in all the branches.

Installation of a new computer network, a telephone line, BMS system or CCTV means a necessity of laying a next pair of wires. Maybe a good solution would be installing a structural wiring system? The universality of the solution consists on using only one kind of a wire, a joint and a stick in all systems. A transmissive cabel is a 4 paired twisted pair cabel of two kinds: STP or UTP, the choice of using one of them depends of conditions in which the systems works. If there is a need to connect a phone or a new computer to a network it is no problem. Each final point of structural wiring can be either a connection to any system by easy connecting a crossover wire to a distributive switch. Obviously the structural wiring system is not only a transmissive cabel. It is a whole range of components that let easy cable infrastructure managing. The system have an open character which means that it may work with every telecommunication and network system even with the one that is to come into being in future. The system is the solution from the last decade of XXth century created with the thought of XXIth century.

Do you want to have a fast data transmission rate? Do you want to use multimedia, and have a fast access to Internet. An optical fiber wire is the best solution! It has very good transmissive parameters thanks to what it surpasses a copper wire in terms of transmission rate speed. Optical fiber wiring is used where exist physical limitation in relation to the length of copper wire or if a big capacity is required. A very important feature of optic fiber wiring is lack galvanic separation, in other words, lack of electric connections between a transmitter and a reciever.It secures one of devices from demaging by voltage. Because the data carrier in optic fibers is light, transmissions are resistant to exterior electro – magneric field including interference.

Although, over a hundred years passed from discovering a telephone and there have appeared new ways of communication, we still use public telephone network. A stationary phone is needed in every house and office. A functioning PSTN ( Public Stationery Telephone Network ) works according to the rule of telephone lines comutation. A telephone installation connects a subscriber with a service deliver. For objects where there are a lot of subscribers are used telephone exchangers. There can be two ways of building the instalation. In the first kind called conventional, there is used a normal telephone wire. The second one, that is more universal and advisable, uses structural wiring and it is called integrated. In a modern buildings or housing estates there is used structural wiring which one of the advantages is a possibility of using modern digital technologies. They displaced significantly analog technologies. A stationary telepone is said to be used for many next years, and that is why we suggest you install a modern integrated telephone system. It will give you needed flexibility and connecting a new telephone line will not be any problem.Well made installation, with suitable configured interior telephone exchangers is a guarantee of well work of the installation

The ones, who want t move freely without resigning from connecting a computer to a local computer network, can be offered local wireless connections. These connections are used where using traditional wires is troublesome, or where communication is needed regardless of location. The networks consist of suitable transmitters and recievers. Connections are realized with the use of infra – red or radio transmission. In the infra – red transmission is used a wide band what allows to send signals in a very high frequency. The disadventage is a requirement that there cannot be any obstacle between the transmitter and the reciever. A narrow band radio transmission consists on work of a transmitter and a reciever on the same frequency. A signal is spread on a large teritory and it penetrates obstacles. A wide frequency band consists on generating a signal which momental spread is described by a common code for a transmitter and a reciever. However a microwave transmission is a system built of two directonal aerials which are directed to each other. They send a beam of electro – magnetic waves and focus received ones. This solution is used to connect two local computer networks situated in two different buildings. The adventage of the solution is lack of a wire connecting two points. Sometimes cable instalation is impossible or very difficult. Dependingly on needs, one of wireless systems to connect computers. Maybe installing a wireless system in your company is worth considering.

The main function of cable television is distributing a multichanel set of signals from a retransmissive station to subscribers’ recievers. In order to deliver a program to subscribers, a suitable wiring infrastructure installation is needed. High frequency TV signals are distributed through subscribers’ network built of coaxial wires. As well an analog transmission as a digital wide band transmission ( used also in LAN and WAN ) can be used in a classical system. In a broadened version with an additional return chanel, there is possible an interaction. It is essential when a wide band system is used for an access to Internet or for Internet sale systems. In subscriber’s side there are used interactive codecs and digital – analog decoders to decoding paid TV programme. It is essential to remember that through the agency of a coaxial wire, we can use Internet, telephone, and we can watch TV programmes offered by an operator, and have an access to a satelite signal. Today we are accustomed to all these services.. An access to a modern cable television for occupants of many modern housing estates is obvious. Practically, every new housing estate has an installed cable television network installed. All the networks and systems ought to be well installed and well made.

Ethernet switches and hubs are the most popular devices that are used to data transmission in local networks. As well hubs as switches allow servers and other peripherial devices to cooperate with a computer network. The advantage of hubs is a lower price per a port, the disadvantage is lower efficiency. Connections that lead to hubs are called co – divided connections in contrast to switched connections. Switches secure the same possibilities in the field of connecting by the means of network wires as hubs, however the switches use the transmission band more effectively. A switch assignes each connected device a described part of transmissive band. Switches are more expensive, however they turn out to be useful in bigger or overload networks. A suitable choice and configuration of devices as soon as on a stage of network designing, may significantly decrease costs of exploitation and administration. The net ought to be efficient, yet it does not have to be expensive at all. It is worth using professionalists’ pieces of advice, who are able to fit a kind of a network and all required devices to specific needs.

If one has or is going to build an elaborated computer network, using routers may be a good idea. Routers are the devices that send data packets between computer networks. They work in the third surface of a network model. Routers are used as well in WAN as in LAN. Local routers are used when one wants to make possible sending data packets between two or more network segments. To determining data routes are used different protocols end elaborated algorithms. A router reacts to situations such as: disconnecting a fragment of a network or a sudden decrease in capacity. It allows to optimalise routes of data transfer and on consequency it improves work and efficiency all the network. If a new designed network as regard its size is to consist in a few segments, and if we want to use efficiency of installed switching devices, the net surely ought to be equipped with routering devices. A professionalist will advice what and where can be installed. A well designed computer network with a suitable location of routers is a guarantee of efficient and reliable work of a network, especially, when it is used every day.

Everyone, for whom a data transfer throug a traditianal analog telephone line is in sufficient, ought to become interested at new ADSL and ISDN technologies. Thanks to them a normal telephone line can be altered in a fast digital connection. It allows to send voice, video by use of only one medium. ADSL and ISDN connections are fast and, additionally, equipped with other services connected with digital telephone. Not only can they be used to sending voice but also toconnecting LANs. ADSL/ISDN technology is: a pure efficiency, economy snd it makes getting and exchanging information easier. It is difficult to imagine a fast access to Internet, VoIP transmission and videoconferency connections without using modern digital technologies. Their installation is no problem and all reqiured devices are available and their price is getting lower and lower. In many situations ISDN/ADSL may be a great solution tht makes normal phone lines more attractive.

A modern telephone exchanger is not only a device that switches connections between subscribers. Thanks to modern softwere a telephone exchanger can control and supervise telephone lines and connections. It also provides many other services, for example: it rates connections or blocades some kinds of connections, ect.. Should a company know where it telephones and how much it costs? A telephone exchanger is able to do autodiagnosis. A modern PABX telephone exchnger thanks to modular construction and flexible softwere it is easy to develop. A modern telephone exchanger makes its user’s work easier and it lets do savings and shortens time dedicated for other activities. Not always we are aware how many functions a modern telephone exchangers has. It is high time it appeared in your company.

Today voice can be send through computer networks without using taking part in it a telecommunication service provider. If costs of telephone connections in a company are high, it is worth using Voice over IP service. The technology consists in sending compressed voice through computer networks that use IP. Within the same medium voice communication and data exchange between two distant points in real time can be connected. And what is more one does not have to bear high costs.Using this kind of data transmission becomes more and more popular among individual subscriber of PSTN and it is profitable in the event of long – distance calls. It is possible to save 60% on long – distance calls. Today a suitable computer equipment, fast and reliable computers networks are accessible. Just take a go!

According to psychologists, nothing can replace a personal contact with a client, a co – worker and a superior. Not everything can be explained or passed on through a telephone call or e – mail corespondency, because as it turned out from psychologists’ examination, one of the most important element in contacts with the others is a nonverbal communication for example a facial expression, form which one can notice whether his interlocutor has a good mood or not. Is it necessary to go to a distant part of a country or to organise a meeting gathering workers from distant company branches? Today organising a videoconference is enough. A video conference is nothing but a telephone connection with video transmission in real time. This is a solution that replaces business travels and allows to save money and time and at the same time it gives an impression of a personal contact with sombody who is far away. The most important is the fact that organising this kind of conferency does not require any special and difficult accessible devices. The idea of this solution is to use a normal transmissive line to transmite sound and video in a real time through an existing telecommunication infrastructure. If one uses this way of personal contact with co - workers, he will come to the conclusion that it is more useful in making decisions than contacts by the means of telephone, fax or e – mail. It is high time you forgot about long travels in orter to have a short meeting.

Local wireless connections turn out to be useful everywhere a local network installation is either impossible or troublesome. Its adventage is securing connection for a user regardless of his location on a determined area. This kind of networks consists ofsuitabl transmitters and recievers. There are placed access points on an area where a network is to have a range. The points are connected to a local computer network. Its users use radio cards installed in computers or PC radio network cards installed for example: in notebooks.Dependantly pn needs there are used different configurations. When a transmitters location of a wireless network is designed a primary rule of an easy access from every place is taken into consideration.

Almost everybody experienced at least one sudden disappearance of voltage suppling a computer. Difficulties with power supply can lead to computer equipment demage. A solution can be using an emergency power supply adapters (Uninterruptible Power Supply). They are an alternative source of wireless power suppling that is disigned esspecially for computer environment. There are used bateries from accumulator that supports voltage for receiving devices in case of voltage disappearance from exterion electric line. Additionaly, UPS power supply adapters eliminate side effects that occurs in electric line that have an influence on suppling voltage parameters for example: a short voltage disappearance, decreasing a nominal voltage value, sourges which value is a few times bigger than a indicating voltage value, suppling votage fluctuations and high frequency interferences. Only well disigned and installed power supply system and suitable emergency power supply adapters can protect expencive equipment form demage and allow it to work well. It is worth preserving oneself from a problem.

Proper energy suppling depends mainly on correct work of medium voltage supply. It is useful to send energy of local range and energy transformation to voltage level in receiving sockets. A crucial meaning has also a correct design and installation of medium voltage system wiring, because it will decide about comfort of power suppling and possibilities of low voltage wiring development. An adventage of a correctly designed wiring are lower costs in future. If it turned out that medium voltage wiring needs development it should not be connected with the need of medium voltage wiring rebuilding. It is essential to remember how many systems use and devices use electric energy today. If we want wiring systems to be safer and secure constant power supply for us, we should pay a sepecial attention to medium voltage wirings.

Low voltage wirings are installed in every object. This kind of wiring are a complete infrastructure that secures energy distribution for devices supplied by 230 / 240 V. Well installed wiring should fulfil its task regardless of a kind of a connected reciever or kind of the work it carries out. The wiring has to fulfil all regulations being in force that guarantee users' safety. The system ought to be universal which lets easy development in case of need without bearing additional costs. A disign of low voltage wiring ought to be thought over and it ought to take into consideration all predictable future demand for electric energy. Every development is connected with eventual breaks in power suppling for other recievers of electric energy, thus, it is worth avoiding it beforehand.

A stable work of network devices is essential today. Every inference is a big problem and it can cause equipment demage or data loss. The best and a certain solution is installing a suitable wiring that would meet network expectations. This kind of wiring is a system separated from a general system. A task of the wiring is to provide energy of suitable parameters and secure data exchange. Neither should engines nor heating devices be connected to this wiring. These devices emit interferences that have a negative influence on computers and they can lead to data loss. From that reason a special attention should be paid to wiring for computer networks. They ought to be installed where there are computer systems and where insufficient power supply can result in system work interference. Let's adopt a rule that either a computer or a printer ought to be connected to a correctly checked and dedicated wiring. This is a guarantee of a proper computer network operation.

There is not rather an usable room space where there is not a lighting system. A lighting system has a very importan role, because from a proper light setting its location and way of controling depends parcticuality, aessthetics and labour confort. A lighting system is a general kind of wiring. A correct design and installation of this system is very important esspecialy in terms of: fulfilling all standarts and requirements, practicality, aesthetics and durability. A big choice of asortment choice allows to designing and making an intelligent and energy - saving systems. A place of work ought to be lighted in accordance with the rules of ergonomy and to be energy - saving at the same time. Fulfilling ergonomy rules in lighting results in increase in work efficiency. Lighting systems ought to meet Labour Law expectations. It is worth having an aesthetic and well installed lighting system. Lightng ought to be fitted to a surrounding where it is installed increasing its aesthetic virtue.

The most important is safety! Lack or incorrectly executed compensatory connection (general or local) in rooms such as a bathroom or a boiler house may cause a direct electric shock. A compensatory installation is essential in all objects because it limits dangerous voltages that may appear in case of breakdown between devices, to acceptable value. As well compensatory installations as earth installations are used in objects for the sake of their users' safety. Besides, lack of suitable and efficient compensatory and earth installations may be a reason of electronic equipment connected to wiring in a building. The installations have to be executed correctly so that people staying in a building could feel safe. One should not wait for an accident. Professionally executed installations by specialists give a guarantee of safety for all building users.

Lack or incorrect installation of a lightning rod in case of in direct or direct lightning bolt may lead to an irreparable damage of wiring and all devices connected to it. It is essential to take into consideration how many expensive devices may be connected to wirring. And what is more not every device is equipped in protections from sudden sourges or lightning rods devices because of their high cost. A task of exterior lightning rods is to pipe away of lightning current to ground. Disigning and executing of an effective and well fitted to an object and atmosphere conditions is a task which requires an immense knowledge. This kind of installation is essential because of gigantic material demages caused by lightning currensts. Lightning rod installations ought to be installed in every object.

There are places where power supply is necessary regardles of existing wiring. One must not allow to power supply disappearance in hospitals, banks, airports, informatic and telephone exchangers. In that places only UPS and electrical unites may guarantee constant power supply. Energy provided from a substitute source of power supply ought to have as high level as possible and guarantee that work lenght and effectivity is sufficient. And that is why so essential is suitable choice of devices so that they meet users' requirements. The installations ought to be correctly designed and systematically measured and tested. If the installation would be in your company useful, it is worth installing it without waiting for effects of power supply breaks.

All devices can be demaged during their exploatation. Also their parameters can be changed from different users. Wiring, as every other product, has to be designed, checked and given to ese. An integral part of this process are measurements and inspections. In that way one may guarantee long and effective work of the entire system. Presently, there are regulations in force that require checking installations for the sake of their users' safety.Incorrect work of installations is a danger as well for human life as devices. Costs of a breakdown are difficult to establish, yet surely they are high. Correct measurments and periodical inspections let minimalise probability of a breakdown. Thanks to modern devices installations may be checked in an easy way and it is to prevent a company form expensive breakdowns.

Technical installation working in a traditional building od independant and cech of them is checked separelty. It may be troublesome, because there are a lot of them for example: aircondition, lighting, fire system. A building may be also equipped with alarm, access control system, and many others. Managing so comprehensive systems consists in work monitoring and discovering devices that are out of order, repairing them, modifications and development. A practical solution for users is creating one integrated system that supports operators' work. Building Managing System integrates all systems and creates an easy to manage structure that reacts on occurences connected with work and breakdowns of all systems. In one place there is gathered information and there is taken a decision. For example an operator may be informed that it high time some elebents were chnged. If managing of installed systems becomes more and more difficult it is worth being interested in installing a BMS.

Access cards, locks and other protections are not a problem for a burglar. Only a modern and professionally installed secure system that co - operates with a mechanical protections is able to guarantee a good level of security. A burglary signallisation system is to detect and inform security services about an attempt to violate or violation of a supervised area. The system allows to signalise if there is a life hazard as a result of an assult. A wide range of sensors, information exchangers, optic and acustic signals and devices to alarm transmission allows to generate specific alarm annoucement directed to security systems. Along with crime increase there must follow development of security systems. That is the requirement. It is worth installing a burglary and assault system. What a pity that a lot of people who are responsible for security install these systems after a burglary or an assault.

We do not want outsiders to stay in our office. From that reason systems of access control are more and more popular. They protect an object and keep using it easy and comfortable. A correct design prevents outsiders from entering an object and it organises motion of entitled users what in concequency minimalises posibility of access to protected objects. It is always known who brought an outsider to a protected area. Thanks to access cards, every user is identified by a system what makes lpossible to confer entitlements to staying during described hours and days in protected rooms or areas. A system generates detailed raports about all chosen events. Integrating an access control system with BMS makes it possible to use data about number of people remaining in a building to controling other systems for example: aircondition, ventilation and lighting. Correctly designed system protects an object without introducing difficulties.for workers. Work in a safe environment.

According to law regulations being in force a lot of objects is obliged to have fire signalization system installed. Even if regulations do not concern some kinds of buildings their owners decide to install this system because they want to guarantee safety for all people remaining in their building. A task of fire detection and signalization systems is early fire detection and alarming. Thanks to it follows informing fire brigades and there are taken steps to start extinguishing action and evacuation. Connecting special fire exchangers with suitable sensors and executing elements in a uniform system allows to start a fast action in case on fire. It is possible to integrate this system with other systems of BMS. Fire detection and signalization system may limit material demages an save human life.

Although, we do not like it, disciplining workers in work turns out to be essential and it is conductive to improving work effectivity. The system supports a company managing of any profil of activity. It can co - operate with systems of earning and staff departments which makes labour time accounting easier. Besides, it controls a number of enterings, leavings, latenesses, overtimes and breaks. The system allows to constant inspection of worker's presence statistics and makes designig work harmonograms or raports easier. Thanks to the system it is possible to eliminate many mistakes in accounting workers' time of work. It has a positive influence on improving discipline. Only presence of the system mobilises workers. Connecting this system with other security systems and system of access control improving company safety and organisation. The system makes fulfilling requirements that results from labour law easier. What you have to do is only to notice advantages of the system and ues them.

Today it is possible to observe other places and surroundings from one room. It has a great meaning in terms of security systems. CCTV is an important supplement to security systems. CCTV is used to observe a protected building or area and it allows to have a possibility of visual verrification of events on an observed area which results in increase in safety level. Besides, thanks to archivisation of recorded images it is possible to explain a course of events which could escape one's attention. Additionaly, CCTV co - operates with other security systems such as: an anti - burglary system, a fire system, an access control system what allows security services to react in a very short time. CCTV may be a great supplement to existing security systems. It improves sentries' work completing their rounds.

Not always workers fulfil their duties as we would expect. In case of responsible work it has a great meaning. Sentries' control system was designed in order to control work of these services in an easy way. It makes possible recording sentries' or other services of that kind, without a possibility of disturbing work of devices that belong to the system either by work conditions or intentional and not intentional interferences. The system foists sentries' routes and and time bracket, mading services fulfil their duties, and a generated raport gives grounds for each worker's work assesment. Scientific researches confirm that in objects where the system is used there reliability of routes grows. Improving sentries' work value, we increase safety of an object. Wouldn't you like to employ senties who fulfil their duties reliably?

Siren howling sometimes is not enough. In many situations of alarm events signalized by optic and acustic events is not clear enough for hundreds or thousands people remaining in a terrain of an object. In these cases the best are alarms that in a clear way inform about an event. They are designed for voice alarming or to public pieces of information. They can for example inform about necessity of going to a safety exit or to other safe area. They have application in many objects starting from office buildings through stadiums, industrial halls, bus stations, railway stations, airports finishing on other industrial objects. Dependingly on use, they make possible sending annoucements attributed to a given event, a live annoucement or music.They are adapted to co - operate with fire systems and suscribers' telephone exchangers. They are helpful in organising evacuation and transmitting annoucements. Installing this system may result in limiting results of panic and increase people's safety in many situations. It is a very important supplement to other systems connected with safety. In big objects where remain a lot of people, sound providing systems ought to be installed. They turn out to be useful in crisis situation when there is not any other way of passing information on to big groups of people staying in an object at the same time.

Technical possibilities are unlimited today, however, equipment and service is not all. What matters is knowledge and experience thanks to which a concrete information can be given and it is possible to analyse a matter jointly and thoroughly. It gives a guarantee of reliably executed investition because all designed systems have to be fiited to individual needs so that they could meet customer's expectations. All designes ought to make possible farther development, modernisation and use broadening. Well equipped technical background allows to visualise all designes so that an Investor could see how his investition will look like after finising its realization.

On well thought and correctly executed design depends reliability of all instalation. That is why it is essential to pay attention to value of executed designes. All systems are executed by high skilled engineers who have great experience in creating technical designes. On correctness of a design depends a cost of an investition. All prepared designes ought to take it into consideration saving customer's money. A good design is a basis for a success. According to experienced executioners, good designes are realised faster and more efficiently.

After acquainting with demand and all assumed criteria, engineers' team may start preparing designes of: tender documentation, technical documentation or offert enquiry. Dependingly on demands all technical materials that are being prepared accordingly to arrengments and law regulations. All prepared studies are professional executed with high technical culture accordingly to assumptions.

Co - operating is not finished when an installed system is being given to use. An executed realized design has to be periodicaly maitained and inspected. A great meaning has as well a warranty as after warranty service and well organised technical unit. Thanks to it instant consultations and users' training is possible. In case of stating that a device is either demaged or its work is incorrect professional help and support is given by well qualified staff.
