How to Connect HD-CVI Cameras to an HD-CVI DVR

HD-CVI is a brand new CCTV technology that delivers High Definition Video over Standard Coax Cable. In this article, I will explain various options on how to connect your HD-CVI Cameras to your HD-CVI DVR. All of the products I will show are available at http://www.securitycameraking.com.

The first option is the one we recommend the most.

HDCVI Wiring Option 1

As you can see in Option 1 this configuration utilizes Siamese Cable with a Distribution Box. The great thing about HDCVI (High Definition Composite Video Interface) as stated above is that you can achieve up to 720p resolution over Analog Coax Cable. To power the HDCVI cameras in this configuration you will need a distribution box. The one in this picture is a 4-channel distribution box. The 18-2 wire coming from the Siamese Cable connects into the distribution box and the other side connects into the female power lead, which then plugs into the power port of the camera. To see and record the video, you will connect the RG59 part of the Siamese Cable to the HDCVI Digital Video recorder (DVR) via a BNC Connector into the video input jack. The other side of the cable will connect to the BNC port on the camera via another BNC Connector.

In the next option, you will see the same sort of configuration except with a power plug instead of a distribution box.

HDCVI Wiring Option 2

In this option, you will use a 1amp minimum power supply to run power to one camera. If you have multiple cameras, either you can use separate power supplies or you can use 4-channel Output Switching Supply if you are powering up to 4 cameras, or an 8-Channel Power Supply for powering up to 8 cameras. In this configuration above for power, you will need a male power lead to connect to the power supply, attach the 18-2 wire from the Siamese cable, and attach the other end of the 18-2 into a female power lead. Then, just plug the power lead into the power port on the HDCVI camera. Keep in mind you will do this for each camera, even if using a 4-channel power supply. For video, the connections are the same as in option 1.

The next option is the simplest option but not highly recommended (although it does work and is good for novices).

HDCVI Wiring Option 3

In this option, we use a Plug and Play Power/Video Cable. There is no special wiring involved. For power, just plug the power supply into the power adapter of the plug and play cable, and then plug the other side of the cable into the power port of the HDCVI Camera. For Video, connect the BNC from the cable into the Video Input on the HDCVI Digital Video Recorder, and attach the other end to the BNC port of the camera.

In the next configuration the diagram consists of the same setup as above except with a distribution box as the power supply.

HD-CVI Wiring Option 4

In this configuration showing how to connect an HDCVI Camera to an HDCVI DVR, power is generated through a power distribution box. To send power to the camera using a plug and play video/power cable as shown above from the distribution box, you will need a female power lead. Connect the two wires of the female power lead to the port in the distribution box and connect the other end of the female power lead into the power port of the plug and play cable. Then, attach the other end of the plug and play cable to the HDCVI Camera. For video, plug the BNC from the cable into the HD-CVI Digital Video recorder and the other end into the camera.

In the next option, we move on to using Cat5e/Cat6 Ethernet cable for video and power transmission.

HDCVI Wiring Option 5

The great thing about High Definition Composite Video Interface (HD-CVI) is that video can be streamed through either Standard Coax Cable or Ethernet Cable. In the above diagram, the power starts with a plug-in power supply. In order to go from the power port on the power supply to the Ethernet cable, you will need to use a passive video and power balun. The power supply plugs into the power port of the balun and then the Ethernet Cable plugs into the RJ45 Jack of the Balun. Then the other side of the Ethernet cable is plugged into the RJ45 jack of the camera side Balun, and the camera’s power port connects to that balun. For video, The BNC from the Balun connected to the power supply is connected to the HDCVI Digital Video recorder and since the Ethernet cable is already plugged into the baluns, you just need to connect the camera’s BNC port to the other Balun.

In the last option in this article, we use the same configuration except with a distribution box.

HD-CVI Wiring Option 6

In this configuration, things get a little tricky. Instead of just plugging in the Ethernet cable using RJ45 Jacks, you will be working with the raw wires that are inside the Ethernet cable. You will use two of the wires for power and two wires for video. Whichever two wires you use, you have to make sure you use the same two wires on both ends.

For the power, connect the first pair of wires to the distribution box. On the camera side, connect those same two wires to a female power lead, and then attach the power lead to the power port on the HDCVI camera. For video, use another pair of wires from the Ethernet cable and attach both ends to passive video baluns. Connect one Balun to the HDCVI DVR and the other to the BNC port on the camera.

In conclusion, there are many different options to connect the HDCVI DVR to an HDCVI Camera. We highly recommend the first two options for best picture resolution and clarity. Plug and play cables are easy, but the clarity isn’t as good as standard coax cable.
