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

It will vary slightly with manufacturer. Some are designed to be just pushed in, or even twisted in. Check for continuity between the screen at each end and the central pin at each end, and that there is no short between screen and pin. Just one fine strand could cause the short. Most types have a compression fitting - that presses on the screen as the housing is screwed on. The central pin may need soldering too. I find that buying these cables ready made saves a lot of trouble and is cheaper than the parts.
If the cable diameter is too large or small it could be a problem.

If you make informed decisions and approach your penny stock investments with the same thoroughness that you’d use in your other investments, you too can unlock a whole lot of profit potential. Learn here https://tr.im/M3Srr
It’s absolutely true that penny stock investors can make very quick gains. Synutra International, Inc. (NASDAQ: SYUT) is a great example of a penny stock. This dairy-based, nutritional-products company has jumped from a little Bulletin Board operation to a billion dollar corporation. The company finally graduated from Over-the-Counter status to the NASDAQ Stock Market bringing with it 113% gains in less than two months.
This happens all the time and it’s how some of the best investors in the world became the richest investors in the world. Buying some shares for pennies on the dollar and selling at $10 or $20 is possibly the fastest way from being a hobby investor to a super investor

Alot of those connectors were soldered on (the tip). You should try using a piece of coax & then screwing a BNC connector onto that. It's much simpler than preparing the ends.
Radio Shack should stock them.

BNC can be adapted to coax with an adapter, crimp on a normal tv cable end to the coax. You can then buy a "F" to "BNC" adapter at radioshack. Screw on the adapter and your set. Radioshack also sells the tv cable ends as well as the crimper you'll need to do this. I bet your electrician may have the crimper and the ends. This way you know you will be fine. I work at radioshack and we also sell twist on bnc ends for RG-59 coax and RG-58, but not for RG-6. I'm betting you have RG-6 since it's most common, and it will work fine and is shielded better than the other cables.

do you have a radio shack store or a electronics store around. they make a adaptor for that allows you to use a f connector cable, for a video cable. here is a link that may help. http://www.shop.com/+-a-f+to+bnc+adapter-p46418031-k36-st.shtml

Forget the electrician.
Get a Radio Tech or wireman in who connects up BNCs for a living. They are dead easy to do, providing you know what you are doing.
If all else fails, buy in pre-wired cables from someone like RS Components or maybe Maplins.
