Setting up outdoor cameras over long distances

[user0001]

Hello!
I find Amcrest to be the best for my needs so I have a dozen or so outdoor Amcrest cameras. Overall I am very pleased with them.

But here is my dilemma. I have at least 3 cameras that are 500 - 700 feet from the router and even though they do pretty good considering, there is the expected lag and broken recorded video due to the sheer distance. On the farthest camera I have a TPLink range extended on the back wall of the house in direct line of sight with the farthest camera. It's on the bleeding edge of reception and struggles.

What I want to do is remove the Wifi camera (700 feet from the house) and change it to a wired camera with higher resolution (8MP instead of 4mp). But it's above my pay grade to do this.

Can someone give me a basic overview of how this would best be done in terms of what equipment, cabling and power needs I will run into?
I know I'll need a POE power supply and likely another mid way....an 8MP outdoor camera and outdoor cable. But that about all I know.

Thanks

Well could use unifi Extender that would have connection on the Rec end that you would plug into switch or camera if direct and that would act like a hidden wire.. This works as long as you have a good Direct liine of sight..

Ubiquiti Point to Point would be better than traditional WIFI. Point to point devices, like the Ubiquiti Nanostation Loco 5AC work in pairs to create a wireless link between the devices. They are inexpensive but DO require 24V POE rather than the 48V POE that the cameras use. Ubiquiti has in-line converters to adapt 48V POE to 24V POE. A CLEAN line of sight is required. "A few trees" isn't going to reliably work.
