In order to replace factory plug and play BNC Connector and DC Adapter plug for a High Definition Swan Camera in an return air plenum, we have replaced the factory cable with an cat 5e cable recommended to use with the Video Balun and DC Adapter to connect to the DVR. Are there any reasons why the Video signal does not work? Do inexpensive Costco cameras require an RG59 Coaxial Cable?
 
Chances are that you are using the wrong pairing/pin out in the CAT5. There are several ways to decide which wire pair to use for the video signal.

I think that a POE IP camera would work best. Only requires one UTP cable and is powered through the RJ45 connector along with the video. You would need some kind of POE injector to get the power into the Ethernet cable.

Well, kinda. Much simpler than that actually. If the video appears to be scrambled you have the video pair reversed, just flip the video wires at one end. What happens is that the sync along with the video gets inverted and that's what it looks like.

Inexpensive Costco cameras probably won't be real HD. Real HD cameras will be IP based (ethernet) or SDI coax, which is rediculously expensive isn't really seen outside of casinos. It's almost certain that your cameras are regular analog and should work with baluns.

As noted above, baluns are polarity sensitive. Assuming the cameras are 12VDC, the power would also be polarity sensitive. I've used baluns from Nitek, Muxlab, and Gem, and the easiest ones to work with are the ones that have an RJ45 jack and break out the power themselves. The most recent ones I've used are Gem BLN-PVRJ45 which have an LED indicator for power. (cheap too)
