I get these too, but from a different kind of burglar. The 3 letter agency kind. And they do it better. They plant them in tree bark and take bark from the tree they intend to place the camera, doll up the device, then come again later to place it. Blends perfectly. And they put it above reachable height so you just can't walk up and yank it off - you need a small ladder. Like they used to install it.
I've got them on telephone poles, neighbor's properties whom are coven, on trees, rocks, you name it. They use low volt wifi to link to a repeater that then boosts the signal back to a local router, again a neighbor. I have purchased spy gear at detecting this stuff, so the signal, is detectable and there.
If you look, the tell is bark missing from the backside of your trees, so it's less likely you'll stumble over that fact.
Audio and video, on every angle, inside and out.
The life of a many decade, gang stalked victim, still walking around to tell the tale.
