terminating
cables
Every cable needs to be properly terminated to the camera on one end and the recording device on the other. For Coaxial cable, the standard termination is the BNC connector. In most cases the cable you install will require a male BNC on either end.
Cameras typically are supplied with a female connector on a short cable sometimes referred to as a ‘whip’. Cameras also have a polarized connector for power. Many cameras are furnished with the complimentary whip which is attached to the Siamese 2 conductor 18 power wires.
On the head-end (the DVR or NVR) you need to also install a male BNC. Power supplies typically terminate in terminal strips, so all that is required is to strip the wire and tighten it down to a terminal block observing polarity if you’re using DC (Direct Current).
There are different coaxial cable ‘constructions’, so the tools and connectors need to be carefully determined before you get to the job. Plenum and non-plenum RG59 and RG6 all have different insulation thicknesses, and your BNC connectors and the tools you use to apply the connectors have to match the wire and the connectors.
You will find a variety of BNC connectors on the market. Some are screw-on, some are soldered and some are compression applied. For temporary installations, the screw-on type is effective to terminate a coax and connect it to a camera or DVR. No special tools are required to apply a screw-on type BNC.
Compression type BNCs use a calibrated die type tool that crushes the ferrule onto the coax cable in two places. I prefer the compression type for permanent installations.
I got my compression tool from Clark Security (www.clarksecurity.com). Clark has a broad line of video cameras, recorders, cable and accessories.
When getting the BNC connectors and compression tool, you need to know the outer diameter of the cable you are going to be using, then get a compression tool and matching BNC connectors.
Some compression tools have die inserts which can be interchanged in the field to accommodate whatever cable and connectors you will be using.
Stripping tools are available for prepping the coax for the BNC connector.
Two of the best vendors are Dolphin Components (http://www.dolphincomponents.com/default.asp) and Gem Electronics (http://www.gemelec.com)
Each vendor has great products and good websites worth visiting. I use products from each vendor. Dolphin is famous for their Beanie type connectors, and alarm oriented accessories such a RJ 31X kits (used for connecting alarm panels to the telephone line) but they also have a broad line of video type connectors.
Gem has a broad line of communications type products including BNC connectors as well as tools and UTP baluns. Each manufacturer has too many products and website resources to adequately describe here, but each has instructions for how to install BNC connectors worth your time to review.
