That’s a scary situation. I wonder how could someone maintain access to cameras without your WiFi login information? Maybe if the DVRs have cellular access, but I haven’t heard of those before. What an interesting problem. You mentioned your kids, but do you think you’ll ever feel like you’re not being watched?

OP said there's a server room in the basement, so if they are just using the servers as they were and connected that equipment to their network, then the guy could potentially access them.

The easiest way to be sure you’re not being watched is to cut power to them, at the camera itself if you’re really concerned.

True, but it seemed that OP was implying that he wasn’t sure he knew where every camera was. He clearly seemed to be concerned that there was a hidden camera in the clock. What do you suggest for that situation?
