ah ha,
yeah, ive never seen a cam with rca
yup, bnc to bnc is what you want. also, on the back of the cam, is there a small black box with two terminals on it? if so you will need a 12v/24v transformer to power it.
those cameras, more than likely a phillips?, can go 300' before signal loss/interuption/degradation occurs.
phillips is on the high end of the makers
post pics of back of cam if you can, and also of VCR
but, bnc connectors you can get at radio shack. the cable is plain coax, you can get that at best buy, or radio shack. if you cant get a 150' section, get the highest you can get, and use barrel connectors. if your going to use more than one cable, make sure its got a hard jacket and a good shield. some coax comes with a 10 wire shield, which braids, if i recal 1 complete braid every 3 inches, but a good shield has 15+ wires with a complete braid every 1/4 inch. more of a braid, the less signal degradation
