Cabling Tips for Security Cameras

security systemCabling is definitely not the showy part of any security system. Nevertheless, it is an essential component of the system. It may seem complicated. There are many considerations in choosing and installing cables to ensure that the security system functions properly. Cables basically provide power for camera installation and transmit signals going back to the digital video recorder (DVR).

Deciding on the Perfect Cabling

Find out whether the system is analog (alternating current frequency has been modified) or digital (electronic technology). Then, you can figure out the proper cable for installation of your security cameras. Or simply refer to the manufacturing specs on the camera system.

The second step is to determine if your camera is powered remotely or connected to a nearby power outlet. It may be necessary to combine power and video cables. Security power and video cables can run next to each other or within one cable jacket. This makes installation easier by pulling one instead of two separate wires.

Make sure to test the cable before you install the CCTV. Examine each cable at the DVR position just to make sure that the cables are working prior to installation.

Cabling Guidelines

Quite often security cameras require coaxial cables to send video from the camera to your recorder. With the RG59 type of coax cable, it is possible to position the camera up to 600 feet away. The RG6 coax cable, on the other hand, may be extended up to 1,000 feet. Cut the cable according to your preferred length but leave an extra service loop of 10 – 20 feet for future flexibility.

What are the steps to follow?

  • Make the necessary BNC connection on the cable. This is a small quick round connector primarily for coaxial cables.
  • Plug one end of the BNC cable to the camera and the other to your DVR.
  • Strip the shield of the power cable to expose the black and red wires. Then, remove the jacket (at least ¼ inch) from each wire.
  • Put the wires inside the terminal block at the end of the female power wire plait. It should be red on red wires and black on black wires. Tighten screws on the terminals. Plug the camera into the fitting at the side of the braid.
  • Attach wires directly to the positive and negative leads respectively in the power box. Red wire is for positive while black is for negative. This is applicable if you will connect the camera to a multiple camera power supply unit.
  • In case you will attach the camera to a single power unit, connect the male power wire braid as well as power supply to the tip of the tress.

Now, the installation is complete and you are ready to use the system.
