Wow the "likes" poured in, wasn't expecting that many thanks everyone glad you enjoyed it.
You could also use a dedicated RF link to get to that outlet. That would remove at least that part of the cable The best way to buy cable is in bulk, 500 or 1000 feet. If you're running it outside make sure it is rated for outside, UV rated.
Line of sight is problematic from here to that outlet, no clear shot.
Tried wireless from that outlet to where cam 1 is in the field but still needed power out at the cameras location. Had 12v power cables daisy chained together and not weather tight. (Utilizing what I had on hand for testing) worked but wasn't happy and still needed a "wire". Figured screw it if I'm gonna run a wire for a camera back there its going to have to be POE.
I bought a roll of cat6 said it was sunlight, dirt, snow, moisture and direct burial with/without conduit. Doubt it's all "that" but it should last for a few years short of a tree falling on it!
