HDMI Security Camera Connection to TV Monitor

This is how-to use any CCTV camera as an HDMI security camera that connects directly to a TV monitor. The HDCV-3-T BNC to HDMI converter enables the connection between your camera and an HDMI display (TV or monitor). This is the best solution for anyone only wants a live video display of a BNC security camera without any recording.

The converter works almost all BNC security cameras. The following CCTV video formats are supported: analog CCTV (CVBS), HD-TVI, HD-CVI, and AHD. It supports the following video resolutions: D1, 960H, 1mp, 2mp / 1080p, 3mp, 5mp, and 8mp / 4K.

The HDMI converter and video multiplexers discussed in this article do not work with HD-SDI cameras or network IP cameras.

Wiring Diagram to connect a security camera to a TV monitor

  1. Run the Siamese coax cable from the location where you will install your security camera back to your TV / monitor.
  2. Connect the BNC cable to the BNC input on the HDCV-3-T HDMI converter.
  3. Connect the power plug on the Siamese cable to the 12V DC power adapter that came with your camera.
  4. Optional: connect the BNC output to a second video input. For example, you can send the second output to a surveillance DVR if you want to record video.
  5. Connect the HDMI cable from the HDMI output of the video converter to the HDMI input on your TV monitor.
  6. Connect the power supply of the HDMI converter.
  7. Switch the HDMI input of your TV port connected to the converter.

You will now see a live view of your security camera on your TV.

Here is a close-up of how the camera connects to the converter using pre-made CCTV camera cable (BNC connectors and power leads pre-attached).

You also have the option to cut a custom length of CCTV Siamese cable from a spool and attach the BNC connectors, a PT-3 power lead and a PT-4 power lead cable yourself. If you are not familiar with this process, our RG59 Siamese cable wiring guide will be useful to you.

Recommended Cameras

Bullet and Dome Style BNC Security Cameras

I highly recommend all of our Viewtron BNC security cameras (CCTV) for use with this converter. If you do not plan on connecting the camera to a surveillance DVR in addition to the converter, you may as well save some money and choose one of the 1080p resolution cameras. This is because the HDMI output of the video converter is limited to 1080p resolution at this time. Due to a chip shortage that will continue into 2023, the 4K chips are not available. We hope to offer our 4K BNC to HDMI converter later in 2023 or 2024.

The HDCT-3T converter enables you to connect a single security camera to a TV. CCTV Camera Pros also has a solution to display multiple cameras on a TV using an HDMI cable.

  2. The power portion of the Siamese cable is connected to the 12V DC power adapter that is included with the camera.
  3. The power adapter plugs into a standard power outlet near your TV.
  4. Please note that you can use a power strip / surge protector if you need more than 2 power connections.
  5. The multiplexer includes a 12V DC power supply. That power supply is also connected to a standard power outlet near your TV.
  6. HDMI cable connects the HDMI output of the video multiplexer to the HDMI input of your HDMI display (TV / monitor).
