I am running a Unifi LR wifi 554 feet to an industrial site and streaming 11 cameras 24x7 with zero issues.

There is a long access road to this site so just for kicks I decided to see how far this wifi signal actually reaches. I used my tablet to see when it would actually connect to wifi and be able to ping google. I was able to connect to the internet from exactly 1/2 mile. I was shocked. Now this was a straight road and clear line of site to the antenna but I was shocked at how well this worked. I did a speed test from this distance and got the same speed as if I was right next to the antenna.
For the price this is may be a better solution.
At anothe site for the same client we had to get the Wifi Signal abot 250 feet and then inside a steel building to various devices.I used the same device to get wifi to the building then I installed this in a Lowes Plastic electrical box on the outside of the building
TP-LINK AC750 Dual Band Wi-Fi Range Extender (RE200)

I then ran Ethernet from the extender through the wall and inside the building to a switch then to each of the devices. This has been running flawlessly for the last 7 months.
Maybe this will give you some ideas for your project.
