I purchased my complete system from...
http://www.Discreet-Surveillance.com
I had excellent results with their color camera transmitter kit. I started with an eBay CMOS set and then upgraded later. The CCD camera image quality was crisper than the CMOS video, and the video was much more stable with less ghosting, blooming, and static. I think all the Discreet-Surveillance cameras use a "CrystalVision" technology to improve image quality.
BTW, they also offered FREE shipping and a full year warranty.
I'd like to find a solid VR headset and give the first-person view a try! Has anybody tried using two cameras for stereoscopic vision?
