Multiple HDCV-3-T converters can be used as a video splitter to connect one TVI camera to multiple HDMI monitors.

If you are looking for a solution to display video from multiple security cameras on a single monitor, please check out our HD CCTV video multiplexer that is also compatible with HD-TVI, HD-CVI, and AHD cameras. We also sell complete systems to display live video from security cameras on a TV.

How-to Connect a Security Camera to a TV

Watch this video to see how the HDCV-3-T is used to connect a security camera to a TV.

BNC Video Input, BNC Video Loop Out, 1080p HDMI Output

AHD to HDMI Converter BNC Video Input / Output

This is how installers connect the HDCV-3-T.
  • An HD-TVI security camera is connected to the BNC video input using coax cable that is compatible with HD-TVI cameras. AHD and HD-CVI cameras can also be used.
  • The HDMI output is connected to a TV monitor using an HDMI cable.
  • The 5V DC Micro USB power supply is connected to the device and a power source.
  • The LED lights will indicate the status.
  • Optional: the BNC video output can be connected to an HD-TVI compatible DVR or to a second HDCV-3-T converter. This will enable live video display on an additional monitor.

Megapixel / 4K Version Update

HD Security Camera to HDMI TV

Update! The current version HDCV-3 that CCTV Camera Pros supplies supports HD over Coax resolutions higher than 1080p and the body has changed slightly. On the side of the device where the BNC input / loop output is located, there are now LEDs that specify what resolution has been detected by the video input. In addition there is a 75Ω / HI-Z switch. If you are using the BNC loop output (optional), this switch should be set to HI-Z. If you are only using the HDMI output (without the BNC loop), this should be set to the 75Ω setting.

How to Connect a Security Camera to a TV

How-to Connect an HD Security Camera to an HDMI TV Monitor

Many customers use our HDCV-3 video converter so that they can display a live view of their security camera on a standard TV using the HDMI video input. This is how it works.

  1. RG59 coax cable with BNC connectors is used to connect the security camera to the input of the converter. Installers can also use these pre-made Siamese security camera cables with power cable.
  2. HDMI cable is used to connect the HDMI output of the converter to the HDMI input of the TV.

Connect HD Security Camera to DVR and TV Monitor

Connect HD-TVI CCTV Camera to HDMI Monitor and DVR

The above wiring diagram shows how to connect an HD-TVI CCTV camera to an HDMI monitor and surveillance DVR. Because many TVI DVRs do not have loop outputs (like traditional CCTV DVRs do), the BNC loop output of the HDVC-3-T is used to share the TVI video signal between 2 devices. In this diagram, we share video from a single TVI security camera with an HD TV and a hybrid CCTV / HD surveillance DVR.

Important Note: Using the loop output is optional. Some customers only want to view their camera live on a TV and DO NOT require recording from a DVR. In this case, installers will only use the HDMI output to connect the HD-TVI camera to a TV.

Connect HD-TVI Security Camera to Multiple HDMI Monitors

Connect HD-TVI Security Camera to Multiple HDMI Monitors

The above diagram shows how an HD-TVI-BL180 security camera can be connected to two high definition TVs using two HDCV-3-T converters that are linked together using an RG59 jumper cable. Here is how it works.

  1. The HD-TVI camera is connected to the HDVC-3-T video converter using RG59 coax cable. You can use this premade Siamese cables for HD security cameras if you want to power the camera from a source near the first converter. Or if you are powering the camera at the location where the camera is installed, you can use these RG59 jumper cables.
  2. The video converter has a BNC loop output which lets you connect the video to a second device using a coax jumper cable. In this installation, we connect it to a second video converter using a premade RG59 jumper / patch cable. A 3rd video converter could be connected to the 2nd one this same way if an additional monitor was needed. You can connect as many monitors as you need by adding additional HDVC-3-T video converters.
  3. Last, use an HDMI cable to connect the HDMI output of each video converter to a TV / monitor.

  4. Security Camera Video Monitor at Retail Store Entrance

5 of 5 Great Guidance!!! October 16, 2023
Reviewer: Ernie F from Maywood, NJ  
I contacted CCTV Camera Pros because I needed a new closed circuit camera after my previous one was demolished (accidentally) by a contractor. My setup is simple, but when I started looking online, everything was very complicated, with DVR, IP, and various other methods of connection, etc. I talked to Mike at CCTV Camera Pros, told him what I needed, and he guided me to what my options were and what I should purchase. He also walked me through the installation. So, in short, I was able to talk to a LIVE person, and they told me exactly what I asked and guided me step by step through what I needed. The camera and equipment arrived how and when they said it would, and installation was a breeze. I am sitting in my basement now, looking at the view of the front of my house, like a window. I could not ask for anything more. I, for one, have no issues with paying a premium price if I receive the quality and customer service commensurate with that premium. If you need a camera, a security system, or any surveillance solution, call CCTV Camera Pros!!!

5 of 5 Extremely Knowledgeable September 1, 2023
Reviewer: Kent K from Mayfield Heights, Ohio  
After watching some Youtube videos I decided to give CCTV Camera Pros a try. They were extremely knowledgeable and understood our needs and knew exactly what I needed. I now know who to come to for all things security camera related. Being a military veteran and being able to support former service members is just icing on the cake!
