VCR Cameras

The problem can be partially solved by installing devices that automatically feed image from the camera, which monitors the site from which you received the alarm. But in this case, the object can escape from the camera's view while the image is formed. Typically, a single monitor (VCR) is served by no more than an image with four cameras. Experts advise not to keep as a normal image from a camera more than 2 seconds. Quad One way of solving the problem is use divider image (quad).

Quad allows you to place images from multiple cameras (up to 4) on one screen. Some of the squarer form an image on the basis of PIP (picture in picture). But the main problem is the declining quality of writing, as recorded at the same time information from four cameras. Consequently, the image quality is reduced by four times. The solution is serve as a multiplexer. Multiplexers solution to many problems described above can be a multiplexer. The multiplexer allows you to send multiple video signals, combining images from multiple cameras (from 4 to 16) and display with simultaneous recording on a VCR.

Recording is done without loss of image quality. This is achieved by a consistent record of personnel from all the cameras on a video (for example, is written 1 shot 1 camera, 1 frame 2 cameras, etc. Frame 1 then 2 cameras, 2 camera frame 2, etc.) This multiplexer allows the output to the monitor all cameras at once, and sequentially, one after another. In the event you want to see previously recorded tape, it can be done using the same multiplexer, connecting it to the VCR and the second for 3 hours looking at what is written down to 16 cameras per day. In this mode, controls the multiplexer two VCRs at the same time – the first, which records the current information from the cameras and the second in which to view the information you previously recorded.
