The interesting thing about security methods is that there’s a way around all of them. The only way to make something truly theft-proof is to make it totally inaccessible to anybody, including yourself. If people can reach a thing, people can steal a thing. As soon as it was announced that the wreck of the Titanic had been found, an expedition was planned to go out there and take some stuff.
Back when I was a stand-up comic, I used to videotape my act occasionally. If I couldn’t lock my camcorder to a pole or something, I would use my cable-lock to elaborately secure the camcorder to its own tripod. It made the whole package harder for a thief to conceal, but also forced the thief to steal both the camera and the tripod, when the camera was all they wanted. Shrewd!
