How to Choose Video Multiplexers?
Video multiplexers come in a variety of configurations and features that conform to certain quality standards. The features may differ in quality of resolution, channels, refresh times, weight, power consumption, etc. When choosing the video multiplexer, you should consider the number of camera inputs you need while taking into account future changes (in case of expansion). Features you need to look for include the following:
1. A time and date stamp that lets you know when any recorded activity took place.
2. An alarm output.
3. Motion detection.
4. Capability to be used with your computer software.
5. Use with either color or black-and-white cameras.
Multiplexers are described as simplex or duplex. This description indicates the number of multiplexing functions they can perform at any one time. Simplex multiplexers can perform only one multiplexing function at a time and will show a full-screen image, whereas duplex multiplexers show split options while continuing to record because it has two multiplexing processors in the same unit. Thus, a duplex multiplexer can display multiple cameras at the same time while multiplex-recording those cameras.
Triplex multiplexers add a third multiplexing processor that has the ability to view live and recorded video on the same screen at the same time. Quadriplexers, or quads, use four camera connections per monitor. Quads can split the screen and display all the four cameras simultaneously. This means that the images are compressed and the image resolution may be low. In comparison, a multiplexer records each camera individually; thus, no loss from compression will occur. This is because when the output of a multiplexer is connected to a recording device, all cameras are individually recorded in sequence.
