Hey guys, I have some CCTV cameras I got but all the orginal wire is short and extensions are expensive.. I have alot of cat5 though and i made a 75ft lead for testing purposes. The goal here is to only use 2 twisted pairs if possible.
So i soldered it up to the camera and supplyed power locally on the camera. Didnt work.
I assumed baluns were just pass through devices that just make it easy for people to go from one connector to another. Now from what im reading it "balances" the connection.
Cat5 is 100ohm, and coax is 75 ohm. The camera and dvr are expecting 75 ohm. Can i add a 25ohm resistor at the DVR end of the cable to achieve the 75 ohms its looking for? if so what wattage does the resistor need to be?
Thanks for the help!
