In California, a security alarm technician has to pass the fingerprint check by the licensing bureau...I am sure other states do the same thing...
This guy added his name to the accounts without permission...Make sure only your name is on the account...
I used to put people in jail EVERY day who’s fingerprints were already in the system. The notion of having their fingerprints in the system does NOT preclude them from criminal conduct!
I checked that only my name is in the users list, and added my son. I also (I think) managed to set up the camera so that I am not constantly spying on my son as he moves around the house. While it's fun for now to tease him about the unforgettable and riveting video of him picking up a cat, that does get old fast. Except if he is at the front door, I can keep spying on him...
