Well, I guess I could point to my snake enclosure camera (which conveniently covers the front door) showing an entry, or if the perps walk through the house, they would trigger the bunny cams, the other snake cam, or the lizard cam. Plus I have my outdoor cameras, although that is my specific scenario.
I’m sure there is an electronic lock on the market that logs when the door is opened, even if not locked. It would be trivial to look at the lock/unlock log and determine that the door was opened without unlocking. A regular tumbler lock isn’t going to give you that kind of info.
These things are still in most modern phones.–
