Security Camera Cable Information and Installation Instructions

Cables used for analog and hybrid IP (HD-SDI) are based on a standard called RG59.  These cables look like those used for cable TV.  We sell both pre-cut (PNP) cables and cables on 500 and 1000 foot spools (RG59).  Pre cut cables typically come in lengths of 50 feet and 100 feet.  Because they are thinner than cables on spools they should not be used for distances of more than about 200 feet.  They come with terminations for video and power connections.  Pre-cut or PNP cables come pre-terminated for power and video.  We do sell extenders for these cables, but this is not recommended as every spot where cables are joined is a source of video loss and power loss and possible cable disconnection.

Cables on spools are typically thicker, and the ones we sell are UL listed and 95% copper.  Video runs on these cables can typically be much longer.  For regular resolution cameras, runs of up to 700 feet have been used.  However, clearly shorter runs have less video and power loss.


Plug and Play Cables

Our premade cables typically have connectors for video and power.  We do have a limited stock of premade cables that also carry audio, but we suggest that you check for availability before ordering.
All of the DVRs and Security Cameras that we supply have BNC female connections. If you require an RCA connection for an additional device such as a TV or VCR you will need to purchase a BNC to RCA converter so you can use the proper cable for connection

RG59 Coax Siamese Cable

RG59 Siamese Cable contains a video coaxial cable and a pair of 18 gauge power cables in one jacket. RG59 is a heavily shielded cable which is better insulated against interference and better to use when there is a long distance to run between your Security Cameras and DVR. RG59 is also more durable than PnP Cables. RG59 cable can be cut to the exact distance between each Security Camera and your DVR. The disadvantages are that RG59 does not contain an audio cable and installation is not as easy as the Plug and Play Cables because of the special tools needed and requirement to cut and fit each cable run.


When you order a Surveillance System from us with RG59 cable, you most order  2 BNC Male Twist-On Connectors for each Security Camera contained in the Surveillance System. After the length of a cable is cut to run a Camera, a BNC Male Twist-On must be attached to each end of the cable before connecting the Security Camera to the DVR. A stripping tool must be used to expose the RG59 cable before installing the twist-on.


If you order a Surveillance System with RG59 Cable, you will need one Pigtail Male Connector for each Security Camera contained in the System. The pigtail Connectors are used to attach the 18 gauge power cable to each Security Camera. This can be done by using a pair of electric wire nuts. The red pigtail wire is the positive and should be attached to the red 18 gauge wire on the RG59 Cable. All Security Cameras include a female power connection. After you attach the pigtail to the RG59 power cable, the 2.1 plug will connect directly into the cameras female power connection.


If you order a Surveillance System with RG59 Cable and without a Power Supply Box, then you need to attach the Power Supplies that your Security Cameras come with to the power wires of the RG59 cable. This is done by cutting the Camera power supply with wire cutters about 3 inches from the camera connector. The two wires that are left should be slightly separated and stripped using an electrical wire stripper tool or cutter and attached to the RG59 Power cables using electrical wire nuts, as shown to the right. Some power adapters are marked which lead is positive and negative. Most of the time the lead with the white stripe is the negative side of the power adapter.

Security Camera Power Supply Boxes

Power Supply Boxes provide a convenient way to neatly provide power to all of your Security Cameras from a centralized supply. Instead of managing multiple power outlets and surge protectors to individually plug all of your Security Camera power supplies into, power supply boxes allow you to centrally manage power to up to 18 Cameras from a single box. Individual Camera power supplies are not needed when using RG59 cable and a power box. The power cables on the RG59 cable plug directly into the power box.
