The choice of system security

When it comes to the safety of your business need to carefully approach the aspect of the choice of security system. Try to understand the variety of security systems, to focus on how to choose a CCTV system, we shall understand what they are and try to understand on what settings you should pay particular attention when choosing a security surveillance system. To start dwell on the classification. CCTV systems, depending on where they are used internally, the street and hidden. Regardless of the type of video surveillance systems are designed to provide visual observation of the object using video cameras. With the help of one or more video cameras, they allow you to monitor the protected object as a single and different points. To date, there are digital and analog video surveillance systems. At the heart of analog CCTV systems incorporated the use of analog recording and playback of video (VCRs, multiplexers, monitors). Thus the signal transmitted from the camera to the monitor video surveillance is the same as a conventional television signal. Serious drawback, not allowing for today analog CCTV to compete with digital systems, this low-speed recording and low quality pictures. Digital video surveillance systems based on the principle of binary encoding information that allows a few times to improve performance speed of reading and writing data, improves the quality of the signal transmitted by the camera, and improves network scalability, allowing for the need to add is already in the working system of additional sensors and cameras. It is also worth noting the low cost of operating a digital video surveillance systems. Colour images of video surveillance systems are color and black and white. Advantages of the latter are obvious: higher resolution and as a consequence, almost unlimited access to image detail, excellent sensitivity in the dark and low light conditions (the perimeter of the protected facility, storage facilities), a lower cost. However, the color image gives the picture more information about the object of observation and, if necessary, could greatly facilitate the identification and tracing the attacker. Type of recording device-based systems of autonomous recorder, which is a device that connects your camcorder, characterized by a greater degree of specification. To work with the equipment and its maintenance requires skilled professionals. These costs are offset by the fact that the unit is initially oriented and configured to perform security tasks. System based on the PC, where the PCI-slot PC installed a special video capture card, which is involved in processing images from the cameras. Firing the surveillance system may be several options for activating the alarm system: motion detected. Camera triggered at a time when the sensor registers the presence of a moving object in the field of observation. Using this system allows you to save your system resources, facilitates the retrieval of information in the processing of incoming information for the reporting period. Firing the bulk sensor. The system is activated at the time of operation interior motion sensor, which signals the appearance of the object of any nature in a protected area. According to the signal access control system. This option is effective when installing the system at checkpoints, or the facility's entrance. On schedule. Activation of the system occurs in a strictly defined by the operator intervals. Parameters of the video is possible to configure the number of frames per second in the exercise video. Greater number of frames per second allows up to dolisekundy record an event, but this imposes certain limitations on the performance of equipment included in security complex. The company's specialists Access-Electronics, which has more than 6 years of experience in installation of security systems, agree that in real life is enough if the recording speed will be about 6-7 frames per second. This will completely restore the big picture without losing detail, and to avoid redundancy. View the video can be produced directly from the device, which produced a record or remotely over a LAN or the Internet. This will create a semblance of central vantage point inside the protected object, or at any time anywhere in the world to be aware of the situation in one way or another-controlled facility. It is also possible the transfer of information on removable media. When you select a camera worth paying attention to the following specifications: Resolution (Low - 380 TV Lines, Medium - 470 TV Lines, High - 600 TVL), Sensitivity (Low - 1 lx (lux), Medium - 0.5 lux, High - 0,002 Luke ), a microphone will allow you, in addition to picture and sound recording, the zoom function remote control cameras, focal length, which determines the angle of the camera (the smaller the angle, the higher the degree of detail available images).
