They probably have several checkpoints to scan every hour or half hour, I’ve seen places with RFID checkpoints that security has to tap on a regular basis. The idea is that security has to not spend the whole night at the desk.
Now they are likely looking for people breaking in, not a small octopus breaking out, so it might not get noticed.
