Hey guys,
Not sure what the best place to find the answer to this question would be so here it goes:
I have an automotive CCTV video system which consists of a flash-based recorder and analog cameras which output a composite video signal and have a 4-pin Mini-DIN connector (same as S-Video) and what I believe is the same type of cable as S-Video.
The recording unit is mounted in the trunk and one of the cameras will be mounted to the front windscreen. I have a 7-conductor, 18AWG, untwisted, unshielded cable that runs from the front of the car to the back already in place, and I'd like to use a few pairs of this cable to hook up the camera, but I have no idea what its impedance is or if it'd even work well for this type of application.
If I directly soldered the 18AWG wire to a mini-DIN connector, and used a standard BNC screw terminal connector on the other end at the recorder, would I notice any loss in quality as opposed to using a long S-Video cable? I have no problem running an additional cat5 cable if necessary, I'm just trying to avoid using coaxial cable because they take up a lot of room and, from what I've read, actually perform worse than cat5 for video with the proper baluns installed.
The total length of the cable run is about 20 feet. The recorder appears to use 50 ohm BNC connectors, I would have expected these to be 75 ohm.
Thanks!
