How to connect a BNC connector to a coaxial cable?
we recently bought some cctv camera's and recorder. everything works... the only trouble my electrician is having (yes he's from india) is how to connect the BNC connectors (which goes to the back of the camera) to the coaxial cable.
can anyone decribe to me how to do it?
the way we did it is to strip away the plastic cover to an inch, flip back the sheild so it goes over the plastic cover, then cut half an inch off the insulator, leaving the core wire exposed. then we just pushed and screwed it into the back of the connector. now.. it all looks good. but once the camera was plugged and seen, the quality was VERY BAD. not how it suppose to be.
NOTE: there is no interferance with other cables and the distance is not a problem (as we tested it with a 20cm cable). all camera's are working 101% as was tested before purchase.
are we doing anything wrong. please advise. Thanks in advance.

For most BNC's you (no way to draw here) need about 1/4 inch of the center conductor sticking out of the white insulation and about a 1/2 inch of that sticking out of the cable, with the ground foil or braid folded back over the outside jacket again about a 1/2 inch or so. some connectors are solder-less and some you have to solder the center conductor to the little needle that is in the front of the connector.
There are several types of coax and other connectors (RCA, F, Motorola, Amphonal, etc. to both BNC male and female adapters
