Cam,
The RCA and bnc are adapters that you can wire yourself. With RCAyou basically have two wires that run the video and two that are power for the device(yellow and grnd., and red and black or grnd.) You also have white and black for audio. All of these can be wired by yourself. The leadsshield will come off and you attach the wires to the two parts of the plug. One usually is screwed to the central probe and one to the shield(grnd.) that surrounds the lead wire. easily done. The BNC is a usb type device that has from a few wires to about 10. These can be seperaed out from its cable and if you know their wiring scheme cam assign RCAs to each wire and then plug it into the apropreate device or plug. For the two cameras that I have (Runcam and Mobius) there are 5 wires to the usb. Power, grnd, audio, and video and one unused wire. This wire is shorted out to the video so that when it is turned on it tells the camera to output the video to the cable. you then hook this up to a monitor video wire and voila you have video of the camera in front of you. The bnc is for wireless setups and they are very expensive(for now anyway)
I took my board camera and hooked a RCA for the video(they come with a cable that gives you the video out) I ran a short cable to the cable from the monitor to the original camera that came with the setup(a small 400tvl camera) This cable was a 4 wire cable, power, audio, video, and grnd. Cut that connector off and separate the wires. I had to turn the monitor on and use the 12volt setting on the multimeter and run the other lead to grnd. Any reading tells you it is the power wire so I hook that to the power lead to the board camera. I then look for the common wire (grnd.). A buzzer on the ground or common channel tells me which wire that is. That leave two wires, audio and video. Hooking the video wire from the camera to one and you get nothing. That is the audio, as I have no audio on this camera. So that leaves the last wire as video. Hook it up and I have video on my monitor. You can get all you need at Radio Shack, if they haven't closed down all their stores in your area. If they have, order from any electronics store. Only cost a few $. If you don't have it get a good soldering iron and lead solder.
The board cam I have is 800tvl. Got it here: Sony 960H CCD Effio-V 800TVL Ultra WDR Camera 2.8mm Lens OSD
This camera and most of the others come with a powerful OSD board that you can program many features of the camera. It has a wide dynamic range that gives great images in all sorts of lighting conditions.You want it with the 3.6 lens. BTW most of these lens if too wide will give you a fish eye picture. You want the flattest lens you can find, thus the 3.6 The 2.8 and 2.4 will give you that fish eye. Most of these lens are set to infinity for focus. Focal length only comes into play when something is really close up. Go to Utube and search for these and other cameras and lens, and they will critique them and tell you what is good and what is not. I can give you a list of these guys. That is how they make a living. Their revues are what drives these company's sales. BTW look up how to make RCA jacks on Utube. They might even have BNCs If it were not for Utube, I think I would never have finished building my car. I have learned so much on there. TIG welding, how to paint my car etc.
