So back in the day the way you’d burn out a security camera was to swap out the diode in a pointer with a CD/dvd burner laser. They’re practically invisible and can pop baloons or start fires from about 50ft. Then the real trick is to get underneath the camera, you can reach just into the field of view and the lens will make sure enough of it gets to the camera to damage it. To an uninformed observer it just looks like you’re trying to light a smoke or tie a shoe or check a text.

Things have changed since then, but I can’t imagine that much.
