I bought one of the Harbor Freight 4 camera video surveillance systems to keep an eye on my driveway and yard. Answered
Two problems arose.
1. Cable distance. "Tech support" says the 'cables' can't be more than the 60' that comes with the system because of loss of signal...( obviously never heard of Instructables.com)....The wires in question are very thin <1/8" with RCA and power connector on one end, BNC and power connector on the receiver end.
Can I adapt the RCA camera up to exterior coax and run a larger 12V power cord alongside the coax, then convert the video signal back down to the BNC connector and achieve a 'boostable' signal?
2. I have solar panels and 12 volt batteries throughout the property, sheds and garage. Would I be able to just power the camera locally instead of running a power cord from the receiver power supply to the camera?
And.. what's a BALUN?
