A lot of the time, owners of surveillance systems struggle to figure out where to view or display the feed from the surveillance system that they purchase. The system described in the blog can be used as a standalone live video display system or it can be used alongside a video surveillance DVR if you need to record your feed for some reason. There are a few important things to consider when it comes to displaying the feed:
- The cameras must be hard-wired to the video multiplexer. It is important to use an RG59 Siamese coax cable. Why would you do that? The reason being that the multiplexers support analog CCTV cameras and HD over Coax security cameras.
- The video multiplexer should have both an HDMI and VGA video output that should connect to the video input which connects it to the TV/monitor.
- The multiplexer should support various screen layouts so you can select one based on your needs.
Extending cable distance using HDMI over CAT6
An issue that bothers owners of surveillance systems in a lot of scenarios is that the display of the security camera feeds is not placed anywhere near the multiplexer. An HDMI over CAT6 system solves this problem very efficiently as there is a built-in infrared transmitter/receiver that lets you remotely control the multiplexer from the location of your TV. The whole process that this system follows is like this:
- RG59 Siamese cables are used to wire the video surveillance system to the multiplexer.
- HDMI over Cat6 transmitter is used to connect the output of the HDMI to the input of the transmitter.
- The infrared transmitter cable/antenna that comes with the box is included with the HDMI over CAT6 system which is then connected to the IR output.
- The infrared receiver cable/ antenna is connected to the IR input of the HDMI receiver.
How to use a multiplexer and DVR together
Often times you might want to not only have a live feed showing the camera feeds on your TV or monitor, but you might also want to record them in case you need them in the future. You could use a security camera video splitter that allows you to share the signal that the cameras provide between a recording DVR and a multiplexer. Some DVRs have a spot monitor dual monitor display function and in that case, you will not need a multiplexer. However, most DVRs do not have spot monitors and as a result, a video splitter is a great solution. The process is as follows:
- The security cameras are wired to the BNC video inputs using RG59 coax cables
- The 8 video outputs are connected to the multiplexer and DVR
- The multiplexer and DVR can be connected to a TV monitor and they can be controlled independently
