VCR Camera

By the multiplexer can be connected to an alarm system (to Special 'ALARM' – input). This allows you to automatically view the picture with the camera, which shows the location of violations. Most of the multiplexers are either 'dynamic allocation record time' for each camera. This means that the camera is the most often recorded on a VCR, the picture is often different. Additional devices swivel device. Such devices are composed of several electric motors, managed remotely, which can move the camera in the desired direction horizontally or vertically. Some of them allow you to pre-configure the camera to work in several program modes. When receiving a control signal (eg from an alarm device that is installed on a particular stretch of protected subject matter) the device automatically sorintiruet camera to quality Image is from the desired area.

Other features make it change speed camera rotation in the horizontal or vertical, self-resetting (after working in the 'alarm' mode camera again begins to function in the normal), and adjust the camera on automatic mode survey (in this case, the camera constantly rotates horizontally between two given points in advance, looking swath of land in a particular sector) Motion detectors. Protection of large objects (such as banks, factories, large office) requires a large number of cameras. In this case the duty is necessary to control more four cameras. As a result, effective protection is markedly reduced. The solution to this problem is to use motion detectors. Motion detectors allow you to display information on multiple screens, include at 'Anxiety' spetsvidieomagnitofon, as well as connect to a computer console and the general alarm.

System setup allows you to exclude false positives such as 'rocking the branches', rain, etc. Video printers. Video printer enables print with a monitor, camera or VCR: photos yet, unwanted visitors, staff of the emergency and any others you may have with a recorded cassette Illumination important point for quality of surveillance systems is the illumination of the object.
