We know a guy whose regulator was likely stolen out of his room by a pool guy who had been admiring it the previous day. The resort initially refused to even give him a report for his insurance. He finally got the report by refusing to leave the doorway of the shuttle on the way to the airport.I've often thought about getting a cheap mini motion activated cam for when I travel, just to add another level of protection - or at least accountability. If nothing else, I'd throw it in the safe for when I'm traveling with a bit of cash. I've had something similar happen at a casino hotel. Unfortunately, no hard proof.
Since then, I have thought about using a charging cube with an internal camera in the bathroom where we normally keep our gear.
