HD Security Camera Cables | HD-SDI, AHD, TVI, CVI, CCTV Siamese Coax
The coax cables on this page are made for HD security cameras (HD CCTV cameras) including HD-SDI, AHD, TVI, and CVI. These cables will also work great with analog CCTV cameras (D1 and 960H resolution), however they are a higher quality and gauge than most pre-made cables that are made for CCTV. This is because HD security cameras (HD-SDI, AHD, HD-TVI, HD-CVI) require the higher quality and gauge to transmit the additional bandwidth required by high definition video (720p and 1080p).
The cables on this page are Siamese type which allow installers to run both video and power. You will find both pre-made Siamese cables and spools of RG59 Siamese coax cable on this page. The pre-made cables are available in different lengths and already have BNC connectors and power leads attached.
Pre-made cables make video surveillance installations more plug and play and are the best choice for DIY installers. Click here

This is what it looks like when the cable is connected to the camera.
If you are using an individual power supply, this is what it looks like when you connect the power supply to the cable. The BNC connector will plug into one of the BNC video inputs on the back of your DVR.
Power Supply Box Wiring
If you are using a
power supply box with pre-made cable, you need to attach a PT-3 power lead to the DVR side of the cable. This is because power supply boxes do not use the 3.1mm plug connector on the cable. Power supply boxes have + / - screw terminals.
The wire end of the PT-3 connects to the screw terminals of the power supply box.
Power supply boxes are typically wall mounted near the DVR. This image shows how the video and power cable can be pulled apart so that the cable can easily reach both the power supply box and the DVR.
