Camera Cabling

The RG59 Siamese cable is more heavily shielded so it's more durable and can be run longer distances (up to 1000 ft. without a repeater). It's heavier shielding makes it less susceptible to interference. Florescent lighting in particular can interfere with camera signals. The RG59 is purchased in 500 or 1000 ft. rolls and each camera run is cut to the exact length needed. Since you need to cut the cable and attached the connectors, it is a little more involved to install.

RG59 Siamese cable is a heavily shielded cable which contains both the video (COAX) cable and the power cable (18 gauge 2 conductor) in one jacket. The advantages to using this cable is that its more durable, and you can run it long distances without interference. Also, you can cut each camera run for the exact length that you need. If you are using a camera with audio or a PTZ camera (which requires a data cable connection) you will need to use a special type of RG59 which includes an additional data wire in the jacket.
