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?

A single ethernet run is limited to 100 meters or ~330 feet. You cannot change this short of placing an active repeater in the span, which will itself require power. In addition, it appears that you are equating twisting the ends of two pieces of wire to doubling the power carrying capacity. This couldn't be further from the truth. If you want to carry more current for a longer distance then the entire conductor must be increased in diameter for the entire length of the run. 400 feet is a very long way to try and run a low voltage DC supply.
Does it actually work at that distance. as mentioned you are way over the limit.
Is your problem you just need more power or do you need it to run above 100mbps.
To run gbit it needs to run all 4 pair.
What you are talking about doing is all going to be non standard so it is all going to be trial and error to see if it works with your particular equipment.
So some basic stuff that may help you decided what you can do.
Ethernet at the very minimum needs 2 pair of wires. In most cases this is only used for ethernet no power on these wires. This can leave the other 4 wires to carry power. There are many proprietary solutions to doing POE.
The standard form of poe is called 802.3at or 802.3af. The main difference is how much power they can provide.
Both these are "active" protocols and do not provide power unless requested. This is because they run at 48 volts and 48 volts will damage equipment not designed to receive it. The reason they use 48 volts is because they can get the same watts of power using less amperage. This is done mostly to allow POE to run the same 100 meter limit of a ethernet cable.
Almost all other forms of POE run lower voltages but they provide the power continuously. This lower voltage makes it less likely you fry equipment if you accidentally plug it in to device not designed for poe. The main problem is these type of systems tend to have much shorter distance. Some of the 12volt systems can only run 100 feet rather than 100 meters.
Some options I have see discussed by others on this forum with similar issues with distance.
At this very moment I can not find the link but there is a switch that can run on POE power and then power a second POE device. This is the standard 802.3 form of poe so your cameras would have to be compatible. Using this switch you can get 200 meters distance. The problem is how do you place a switch say in the middle of a field and not have it damaged by weather. Burying it in a water proof case and hoping it does not overheat might work.
The more common method would be to use solar panels and a battery system and then use point to point wifi to connect back to the main location. I guess you could also use solar and batery to provide power and run a fiber to pass the data if you were concerned about wifi.

Found this POE extender. Make sure you can return if it doesn't work.

But 4K stream only need 30Mbps link as mentioned above, have you tried the 4K camera with existing setup?

Again, I am not using POE. I have a separate 2-conductor cable that supplies 12v to the camera. It's 4k so I need about 34-50Mbps from what I've read. How about this? Uses only two wires.

Oops. At 200m it only support 10Mbps. Need to find it's manual.
Yep. Long range PoE+up only to 200m at 10Mbps

Have you considered optical? Kind of the same installation concept. with an active converter at either end. A bit more expensive, but not much chance of anything going wrong.

In looking at the various cable options that those transceivers have options for, anywhere from $120-200 for a 150m length.
