> For example, you might need to setup a camera in some outdoor spot that's too far for a wired connection to be practical (Ethernet only runs so far, and I ain't aware of very many cameras that use fiber), in which case a wireless connection and a solar panel might very well be the way you'd have to go.
Cameras that use fiber exist, but you could also just use an ethernet camera and a fiber to ethernet converter.
> Also, wired connections (especially outdoor ones) have a tendency to be vulnerable to things like wire cutters or fiber-seeking backhoes.
I once encountered a survivalist who would always carry a length of fiber optic cable with him, that way if he was ever hopelessly lost in the wilderness he needed only to bury the fiber and a backhoe would be along promptly to dig it up.
One solution in those cases is to use directional wireless, which is harder to jam, but then you're back to not needing 5G.
If it's important enough you can also attach a storage device directly to the camera so that if there is a temporary network interruption the data isn't lost.
Of course, you also have the trouble that the cameras themselves tend to be vulnerable to things like rocks. Securing something which is out in the open is hard.
> given that a wireless jammer is a much more sophisticated attack strategy than, say, some snips or an "accidental" strike by some piece of equipment
Jamming wireless is not really that sophisticated. It's both easy an inexpensive to do it. The main impediment is that the legal penalties can be rather severe, but criminals are not well known for their fastidious adherence to the law.
