How do I prevent my security cameras from being stolen?
There's a couple of ways to play this, depending on how easy it is to get above/behind the mount point above the camera


Attach a smooth-face bolt to the bottom and put the nut above/behind. If you're mounting to a soffit or plywood, this is the best way to do it because you have no native access to loosen the bolt from the outside. All you see is the smooth face
Use a one-way screw. Not impossible to remove, but not doable with hand tools


Use a non-standard screw head. Star bits are a bit harder to come by than Phillips or straight. There's even some rather exotic heads, with the goal being security through obscurity


Mind you, there's nothing to stop a determined thief from drilling the fastener out and taking the camera (which would involve noise), but these ideas should make it more difficult than using a regular pocket screwdriver.
