CCTV Video Multiplexers, Multi-Camera Monitor Display for Security Cameras

A video multiplexer (also known as a video mux, CCTV multiplexer, or color quad processor) combines video signals from multiple CCTV security cameras and displays the video streams on one TV monitor. In legacy security systems, multiplexers are used to combine video from multiple CCTV cameras to be recorded on video surveillance VCR. For example, if you have four security cameras, each of the four video signals from each camera is synchronized by the CCTV multiplexer and recorded on the same video tape.

Today, video multiplexers and color quad processors are more commonly used in video surveillance systems that have complex monitor display requirements. Many of the multiplexers supplied by CCTV camera Pros support both analog CCTV cameras and the latest HD-over-Coax security cameras. Various screen display configurations are supported. Please read our FAQ to learn more and watch these video demonstrations to see how these devices allow the user to select between single camera, dual camera, quad/grid, eight channel, nine channel, and sixteen channel grid views using the wireless remote control that is included.

CCTV Multiplexer FAQ

  • How does a CCTV multiplexer work? - Video from security cameras is transmitted over coax cable to the BNC video inputs of the multiplexer. Multiplexers typically have one or more of the following types of video outputs that can be connected to a TV or computer monitor: VGA, HDMI, BNC (analog). The software (firmware) built into the multiplexer combines the video signal from all of the inputs and allows the operator to select various displays such as single screen, 4 screen (quad), 8, 9, 16, etc.
  • What types of security cameras are supported? - Traditionally multiplexers were used with analog CCTV cameras. However, the latest HD CCTV multiplexers support analog cameras and the latest HD-over-Coax type cameras (AHD, HD-TVI, HDCVI).
  • How are they installed? - Installation is a very simple process, much like wiring a TV or stereo system. Please refer to this installation diagram.
  • How do you switch screen modes? - The multiplexers that we supply include a wireless remote control that is used to switch between screen layouts. There are also buttons on the front of the units that can be used to switch video modes.
  • Can I use a multiplexer with a DVR? - Yes. Many of our customers used a video multiplexer in conjunctions with a surveillance DVR. This is typical in cases where the DVR does not have a spot monitor output and also if the client want to setup multiple display monitors with different multi-camera screen layouts. In these cases, we help customers design a system that consists of one or more CCTV video splitters so that the video from their cameras can be shared by their DVR and one or more multiplexers.
