In addition to analog CCTV cameras, you can now connect
HD security cameras (AHD CCTV) to the HDMI input of a TV monitor. Watch the below video to see how this is done using a 720p and 1080p security camera.
Please click here to learn more about the
AHD to HDMI converter used in the above video.
If you want to view multiple cameras on a TV at the same time, you can use a
CCTV quad processor (up to 4 cameras) or a CCTV multiplexer (up to 16 cameras) to combine the video signals.
How it Works
- The analog security cameras (CCTV) are hard wired to the video inputs of the quad multiplexer using RG59 coax cable. You can premade RG59 jumper cables like these.
- The multiplexer (mux) has a single BNC video output. You can use another RG59 jumper to run the video from the mux to the TV.
- On the TV end of the cable, the BNC connector can be converted to a male RCA with this connector.
- The video multiplexer processor can be configured to display all 4 cameras on the screen. It can also be configured in other ways such as single picture scrolling with delay, picture in picture, dual picture, and more. You watch the below video to see some of the different screen configurations that are supported by a 16 channel video multiplexer.
How-to Connect a Security Camera to Two TVs
2016 article update: A customer recently asked me if it was possible to connect a single security camera to two TVs / monitors. The answer is yes. To connect a single analog CCTV camera to two TVs, you can split the video signal using this
1 input to 2 output analog CCTV video splitter. You can find additional analog CCTV video splitters here if you need to split the video signal more than once. If you need to share a video signal using HD-CVI, AHD cameras, HD-TVI cameras (720p or 1080p), you can use this HD security camera video splitter.
