Question 400 ft. cat cable connection

[867-5309]

I have a PTZ camera on a pole along a highway 400 ft. from my house. The connection was OK with a 1080p camera but now I have a 4k camera and I need a better connection. Here's my question. Since I have separate wires for the camera's power (it's not POE), I have four wires in the cat cable that aren't being used. Would it help my connection if I took the four unused wires and connected each one in parallel to each of the four being used? I know that would allow twice as much DC to be carried over a power cable but would doubling the wires for a data cable improve the connection? Is there anything else I can do?

contact the vendor and ask what kind of speed you can get at 400ft

The unit at the camera would get its 12v from the camera power supply. I have a 2-conductor power wire that goes to the camera. It's a separate wire from the CAT cable. That's why I don't use POE. I can't put a POE type booster with a power supply in the middle of a field.

You didn't mention you have standalone 2-conductor power wire until this post. Everyone here thought you are talking about the thin wires inside the ethernet cable.

So here is another possible solution. Buy a POE switch/injector you like on the market and then buy this

or earlier mentioned Cudy15

dig a hole at 200ft position and cut the ethernet cable in half and make rj45 connectors using rj45 plugs and connect everything. Of course you need to seal it tight and make it water and dirt proof. This will guarantee the speed even at 400ft. Of course you have to very careful, since you probably won't have 2nd chance making the cables.

Make your own choice.
