My buddy needed an RCA to coaxial converter so he could stream YouTube throughout his house on the coaxial network already installed in his home. He did not have the $20-$30 for the converter and I had one, being impatient he traded me some security cams for it (dumass) so I got these both for $20! I've needed a surveillance system for a while now anyway I have several $K into my custom interior electronics, enough said.
The large white one is a Hitachi VK-C77U and it retails for $399 the small cam is a Swann Secura Cam SW214-SCC and it retails for under $50 I think:
The small one is crappy black and white CMOS quality, supposedly waterproof with night vision but I don't see those LEDs light up unless they are infrared and I just can't see them?? It does however have a set screw on the lens for better focus or zoom so at least the lens is decent. On the other hand I am really impressed with the Hitachi's CCD quality, and its auto focus. I will be using the Svideo interface, it is highly configurable even via remote so maybe I can open up the iris at night via remote wide enough to not even need IF night vision or a motion light:
