Aren't wired cameras fine as long as you use a virtual LAN network for them and don't place them inside?
Axis P1204 has a small camera sensor separated from the camera body by a 25' cable, which makes it easier to enclose and secure the camera body. Not seen that elsewhere, must be a proprietary protocol on that cable, e.g. RPi camera sensor cables can only be a few cm.
It is build like a tank and fully aluminium. If you mount it right you easily can hold a person from it. I bascially made a hole through the wall for the cables and mounted it directly to the outside wall.
For now im quite confident that nobody will be able to remove it without much fuzz
