Here is the message from a neighbor.
Hi there. I have a concern and think the neighborhood should be aware. A man came by my house yesterday that said he was with the company who installed my security system. He asked me if it was working properly and if I had any trouble with the batteries. My system is working fine so I thought nothing of it until last night. I called ADT today and found out that the company that installed my system is actually out of business. I think this man was going door to door and finding out if people's security systems were actually working. I know lots of people cancel their systems and leave the sign in the yard to make it look like they have a system in place.
The man is middle aged, stout and wearing a brown uniform, complete with hat and clipboard.
