I need to capture from BNC

[qwertymk]

Hi, I have a CCTV system and have it output-ed with a BNC cable. I bought a BNC to Composite cable changer and inserted the Composite cable to the TV card but when I open the capture steam with VLC or the program that my TV card came with (TV@Anywhere) I get a blank screen. I was wondering if anyone had any ideas.
Thank you in advance for your help.

Do you have a male BNC to male RCA 1/4" cable or one of the small adapters that connects at the BNC terminal? I have had nothing but problems with the small adapters over the years and always use a cable:

BTW: The BNC is outputing an analog composite signal, just uses a different connector. BNC never made it to consumer gear because manufacturers felt that consumers would have more difficulty with connections over the RCA plug. The BNC connectors lock on and are more robust in terms of accidental disconnects, making them ideal in professional or commercial set-ups...thus why your CCTV system uses them. Best to go BNC at the camera end and convert to RCA at the computer end. Don't convert the BNC to RCA.

It should work. Connect it to a TV (rca end) to see if the camera is working.

BNC has a male pin but a female like shell. The pin is what counts

Did you tried using that same cable to connect to a "video in" jack on a TV? You can only use the process of elimination to figure out which is giving you the problem (the cable, CCTV system, TV card). I would try a different cable first (since it is the cheapest).
