#407: Snaptrap

Rooms in office buildings which are sealed using a keypad lock naturally present a challenge to those people with an interest in seeing what’s inside (possibly even attracting extra attention).

Today’s invention is designed to discourage anyone from speculatively attempting to gain access, by trying a selection of likely n-digit entry codes.

The lock mechanism would be equipped with memory to record the last say 10*n digits entered. If the latest attempts were insufficiently close to the correct code, an embedded digital camera would covertly take a picture of the individual keying them in.

This would allow Security to contact that person later (without mentioning the camera) and remind them that playing with locks is a bad thing to do.
