Closed circuit television mounting and connections are critical to facility and property surveillance. Connection techniques will vary depending on the size of the area and the location of where all security camera devices will be mounted. Additionally, ensure proper lighting and device positioning for optimal security camera monitoring.

  1. Cable Length

    • CCTV connections require various amounts of cable depending upon the physical range of connections, according to Robert Moskal. Larger areas often require more cable -- although a wise technique means using as little cable as possible. Specifically, ensure your connections include a maximum of 400 feet in cable. Reducing cable lengths promises enhanced control over connections, reduced hassle and less excess. For safety purposes, CCTV cable and high voltage power lines must be spaced at least one foot apart.

    Cable Type

    • Siamese cable is an optimum choice when selecting CCTV cable, according to Moskal. Using Siamese cable ensures stronger connections and a more efficient installation. Thin and easy to handle, users can maneuver Siamese cable around awkward areas with relative ease. Additionally, CCTV connections can run on just a single line of Siamese cable -- as opposed to multiple connections with a less efficient type of cable. A single line of Siamese cable broadcasts video and power at the same time.

    DVR Option

    • Power connections may also include the use of a digital video recording device. Specifically, a DVR unit powered by a battery acts as an alternate recording device and a secondary source of energy in the event of a power outage. Should electricity to the camera shut down -- due to an outage or surge -- the DVR connection will keep the monitor running and recording until standard power is returned.
