12v power cable? to cameras

[crow 0]

hi

what cable would be suitable to use for 12v power to 2 cameras

rg59 is 200ft long to dvr

so i am placing 5 amp power supply local next to cameras

about 15 to 20 meters away

and will use seperate cable for power instead of shotgun cable

 

i can only buy 305meters of cat 5 cable

and its too expensive

what will be suitable to buy

from city electrical as there is a shop local to me

thanks

You can use just about anything for power cable. 18/2 is most common, but we normally use station-Z wire (22/4, aka alarm wire) if we need separate power. You can use speaker wire, lamp-cord wire, microphone wire... heck, you could even use 14/3 Romex if you REALLY wanted to. For a 200' run, though, running through 18/2 Siamese cable back to the DVR should work fine as well.
