[QUOTE="Terryl, post: 1070020, member: 369937"] Three cameras with voltage and power rated at 12 @ 1 amp, then a 3 amp 12 volt DC power supply would do quite nice. One possible problem would be voltage drop on the 40 meter cable out to that camera, you might need to go bigger on the wire gauge for that one. Or a variable power supply can help out, you can turn the DC voltage up to compensate for any drop at the camera end. I use cameras that take 24 volt AC power, no drops on them. [/QUOTE]
