CP PLUS HD-CVI DVR:
HDCVI is a new camera technology that allows 720P or 1080P video signals to be transmitted over solid copper conductor coaxial RG59U cable or better. The HDCVI cameras and DVR recorders are also inexpensive when compared to IP cameras. For customers with existing CCTV systems, chances are they are using coaxial cable already and upgrading to a HDCVI system for high definition video makes more sense as it saves tremendous costs of re-running wiring and equipment cost is also lower. For customer looking for new HD camera systems, HDCVI is a great lower cost alternative to IP network cameras, and is also simpler to install as it is plug & play and requires no network configuration for each camera as in the case of IP, which is a common hurdle for many users who are not familiar with networking.
Take the added cost and labor of that extra cable run and throw it out the window with HDCVI. The PTZ cameras of the HDCVI type are capable of achieving that RS485 data connection without the use of an extra cable. It’s all done right through the same coax cable that’s transmitting video.
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 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.
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.
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 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.
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.
