Published on

Multiplexer or MUX in surveillance world is a device that essentially lets several signals to be transmitted into one channel, on one device. What we’re talking about here is CCTV cameras. If you have multiple surveillance cameras and you want to view them all on one monitor, you need a multiplexer to receive signals from all cameras and send them through for recording into your PC, DVR or VCR system. Here are some of the benefits of using a multiplexer:

  • Alarm output to alert you
  • Time and date stamp
  • Motion detection
  • Works with PC software
  • Remote, internet access
  • Color, B&W cameras
  • Allows simultaneous playbacks

Multiplexers come in 2 different types simplex and duplex. While these 2 words may not tell you anything at all, they make a big difference in surveillance world.

  • Simplex Multiplexers – These multiplexers work by providing you with full-screen video on a monitor. It continues to record the view without interruption.
  • Duplex Multiplexers – These are the ones you often see in movies. Duplex provide the ability to view multiple cameras by splitting the screen into 4, 8, or 16 (depending on camera system) blocks. You can zoom in or out and get better view. Widely used in CCTV business.
