Once upon a time, guards doing patrols had to turn keys in various locations along their assigned route, each recording the time the key was turned.

We don’t have something similar in prisons today, using maybe a near-field key fob?

There were cameras in the walkway....That'll tell part of the story. Of course they also likely know how to avoid the cameras.

Wouldn't it be funny if there were 18 1/2 minutes missing.

Many hospitals use automated systems to track nurses doing their rounds, for liability reasons, so they can show that a patient was diligently checked in on during the night.

My home security system triggers on movement, and makes a video segment when movement is sensed.

All these safeguards are worthless, if you don't have a competent manager actually reviewing the logs and dealing with lapses.
