The case file

Someone entered the clinic after closing. The logs below are all verified -- the order has to be reconstructed. What happened first?

The clues

1. The alarm log shows the alarm tripping at 8:16 PM, before the side-door sensor tripping.
2. The phone log shows the cleaning crew's check-in call being logged at 8:07 PM, after the records-room motion sensor firing.
3. The door sensor log shows the side-door sensor tripping at 8:24 PM, before the pharmacy door sensor tripping.
4. The camera log shows the hallway camera flagging motion at 8:12 PM, after the cleaning crew's check-in call being logged.

Who did it?

1. the pharmacy door sensor tripping
2. the hallway camera flagging motion
