Hardware/electronics issues can cause fires from overheating
Facial Recognition software is not working at the level it should be (misidentifying people)
Solutions:
Leave vents to allow for cool air flow throughout the system
If it still overheats and is missed through testing, then the owners who encounter this will be compensated with a replacement.
Conduct extensive testing on the facial recognition software and the durability of the camera.
Have a "repair shop" for the locks and have an auto detection policy that determines the status of the camera to ensure that no one is using a faulty/broken camera.
