Way long time ago relating to use of Axis CCTV cameras and WIreless covering a large area used wireless bridges for a commercial CCTV view of multiple warehouses and a large fenced in area for commercial construction do whats (with a high fence - barbed wire).
Before installing this system and reason for installation was that one day a truck rolled in the yard rolling over the fences and stealing a few large job site (gas and oil job sites) generators valued at a few thousand dollars (over 100K worth).
Really above the issue related to creation of the willy nilly infrastructure of the site (it was a permanent location).
I did see a lot of this with same company and implementation of security post issues which is truly a mickey mouse to do business.
I have seen this methodology of wireless CCTV and WAP's used for camp grounds etc...
For residential today you can do similiar at a reasonable cost.
Here you would utilize the network port on the camera and connect it to a wireless device and directional antenna going to your home.
Years ago (early 2000's) created a double DD-WRT router wireless bridge to the neighbors house a few hundred feet away for their internet access. Basically it was a dedicated Linksys DD-WRT router with directional parabolic antennas made of paper and aluminum creating a bridge between the two homes.
For one camera with wireless you could install a dedicated and directional WAP pointing to the camera. You can also make directional parabolic antennas on each end for better wireless. Seen this done using an old direct TV dish.
