Security Camera Cables, CCTV BNC Camera Cable, Video & Power
CCTV Camera Pros sells various lengths of pre-made security camera cables with BNC and power connectors. This type of cable is known as Siamese cable and BNC video power cable. Our pre-made surveillance camera cable enable quicker installations for DIY and professional security installers.
Our pre-made BNC camera cables are HD CCTV rated. These cables are tested to work with the following BNC camera types: analog CCTV (CVBS), AHD, HD-TVI, HD-CVI, HD-SDI. AHD and HD-TVI up to 4K resolution has been tested and verified. We guarantee to provide the highest quality plug-n-play security camera cables on the market.
These cables allow you to run both video and power in one cable. Each cable has a male BNC connector on each end to connect to your security camera to your DVR. The power side of the cable can connect your surveillance camera's power lead to an individual power supply or to a power supply box with the use of a PT-3 power cable lead. Click here to

 Please take a look at our pre-made CCTV cable wiring guide to see many examples of how these cables can be used to wire analog CCTV and HD security cameras that work over coax. Also, refer to our FAQ.

What is the difference between these pre-made security camera cable and RG59 Siamese coaxial cable?
Pre-made Siamese security camera cable comes various lengths with the BNC male connectors pre-attached both ends of the cable. The security camera power portion of the pre-made cable has a female 2.1mm power connection on one end and a male 2.1mm power connection on the other end.
RG59 Siamese coax cable comes in raw spools with no BNC connectors attached. This allows installers to custom cut the cable length so there is little or no leftover slack. It is also easier to run cable through walls when there are no BNC ends (because the hole can be smaller).
The video cable on the pre-mades is stranded copper so that it is more flexible. The video cable of RG59 Siamese is a solid copper center conductor. The solid center conductor allows the video signal to be run longer distances. For example, you can run analog CCTV camera video 700 feet using RG59, but are limited to around 250 feet with pre-made cable.
The power cable in RG59 Siamese is 18 gauge. The power cable in pre-made cables is typically thinner and can not carry low voltage power as far.
In summary, CCTV Camera Pros recommends using RG59 Siamese when possible. If the distance from your DVR to your security camera is 150 feet or less, pre-made cable works well. For cable runs above veiling tiles or other applications that are simple, pre-made cable is a good choice. If you are running your cable through drywall, wood, brick, concrete, or outdoors we usually recommend using RG59 Siamese cable. It is much more durable and can run much longer distances.
Can two security camera cables connect together to extend the length?
Yes, but this type of application should be used with caution. Installers can use one of these
double female connectors to connect the BNC male connectors of two cables together. The power cable is male on one end and female on the other, so no additional connector is needed to connect the power portion of the cables.
The problem that many installers run into power drop. The power cable in pre-made security camera cable should generally only be used for cable distances of 150 feet or less depending on the voltage requirement of the camera.
Can pre-made BNC camera cable be used with 12V DC and 24VAC security cameras?
Yes, BNC camera cable is made for both low voltage types.
Can pre-made cable be cut and BNC connectors re-attached?
No. Pre-made security camera cables are not meant to be cut. If you cut then, you will NOT be able to attach new BNC connectors and the cables will be useless. Same goes for the power portion of the cable. DO NOT CUT pre-made cable!
Can pre-made cables be used with a multi-camera power supply?
Yes, these cables can be used to wire to a
single power transformer or multi-channel power supply box.
Are these cables compatible with cameras and DVRs from other manufacturers?
Yes, these cables can be used as longer replacement cables and cable extensions from all manufacturers including Swann, Lorex, Night Owl, FLIR, Samsung and all others. We have helped many customers who want longer cables or higher quality cables that the ones included with their box store systems.
Do these cables work with 4K security cameras?
Yes. Our pre-made cables have been tested with
4K security cameras including AHD and HD-TVI format.
We now have a complete premade Siamese cable wiring guide. Please reference it to see many examples of how pre-made cables can be used to wire analog CCTV and HD CCTV cameras that work over coax.
Follow these instructions to learn how to connect pre-made Siamese cables to CCTV cameras, power supplies, and a video surveillance DVR.
Reference this diagram to note which end of the cable connects to the camera and which connects to the DVR.
The BNC connector on the camera end of the cable simple pushes and twists onto the BNC connector of the camera. The power lead of the camera simply pushes onto the power lead of the Siamese cable.
This is what it looks like when the cable is connected to the camera.
If you are using an single
security camera 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.
If you are using a
CCTV 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 2.1mm plug connector on the cable. Power supply boxes have + / - screw terminals.
The wire end of the PT-3 connects to the s
crew 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.
