CCTV cabling

CCTV cabling

(OP)
Hello,
I am doing some cabling for a customer, running CAT5e to 2 cameras about 750 feet away. These are 12V DC cameras on a power supply for 4 cameras with 5 amps. I am wondering if the distance will be an issue for the power drop off? The video will be converted with a balun.
Also, if these 2 cameras are right next to each other, can i just pull 1 Cat5e and use 2 pair of the Cat5e for one camera and use the other 2 pair for the other camera, one for video and one for power? Will this cause any issues,,,ie..bleedover..etc.
Thank you in advance for your help.

RE: CCTV cabling

750 feet is a long way for 12v. Many cameras will also do 24v - have you checked to see if that's an option? Or power closer to the camera? You could use a single cat5 - use one pair each for video and have power use one pair for pos and another pair for neg - and share between the two cameras.

RE: CCTV cabling

I had a nice post that had links to tables that would help solve your problem. Unfortunately that post was deleted by forum admins at the request of a drive-by poster. Sorry I don't have the time or inclination right now to find the links again but searching on cctv volt drop should answer your question.
