Hello everyone. I've been working on this all morning and I'm lost. I have a controlled room inside another room. I had a badge read on the interior room at 5:30 am this morning, but no one scanned in the 'outside' room for at least 48 hours leading up to it. I've looked at the video of the camera aiming at that door and I've got nothing. So, either someone is tele-porting into the interior room or I have a ghost.
OR: (my current theory).
The badge reader that is on that door is an OLD prox reader (say 10 years). The wiring leading from that reader to the node is about the same I'd assume. System is S2. Now, the reason this is sticking out to me is because my system is calling it an 'unknown' card/person. I've been getting these unknown reads on this reader (but not the one on the outside door) randomly for some time. Randomly meaning literally at all hours of the night and day, from 11pm to 5am, on weekends when no one is here, etc.
So, is it possible that I've got a short in the Wiegand wires from the reader to the node, or a rat chewing on the wire and causing the short and inducing some sort of Wiegand signal that the S2 node is trying to interpret as a card read?
Or should I call Ghostbusters?
