WHAT IS A VIDEO MULTIPLEXER?

Wherever closed circuit television (CCTV) systems are used, there is often a need to record and display many different camera views. Whether it is in a small retail environment, a large casino, or an airport, multiplexers have become the preferred method of collecting pictures from as many as 16 cameras for recording on a single time-lapse VCR.

In addition, multiplexers allow users to watch up to 16 cameras simultaneously on one screen, either live or in playback. Should a scene require closer examination, the user can select full-screen viewing without the loss of detail, as occurs with “quad” devices that compress four pictures into one for recording.

The multiplexer acts as an interface between the CCTV cameras and the time-lapse VCR. The multiplexer is designed to switch between cameras much like an ordinary sequential switcher. Unlike a switcher, however, a multiplexer should switch at exactly the same rate as the VCR is recording so that just one video picture, or field, is recorded from each camera before it switches to the next camera. The reason for this is that with a large number of cameras, you need to switch as fast as you possibly can in order to minimize the time gap between successive pictures from a given camera.

In most respects, time-lapse VCRs are very similar to the VHS video recorder that you probably have in your home. The single largest difference is that a time-lapse VCR allows as much as 960 hours of video to be recorded on a single T-120 (two-hour) VHS cassette. The total amount of time varies by make and model, but even the lowest cost models allow for a lot longer recording time than a normal consumer VCR.

When you record a tape on your home VCR and play the tape, you see normal motion, just as you do on your television. If you connect one camera to a multiplexer and record the video at the two-hour speed on a time-lapse recorder, motion will appear normal when you play the tape, just like on your home VCR. But as you add more cameras to the multiplexer, the multiplexer has to switch between cameras and there is a gap in the video pictures recorded for any one camera. The more cameras there are, the longer the gap is because it takes longer for the multiplexer to switch between all the cameras. When the tape is played, the motion becomes jerky because of the missing video.
