Hi There are motions sensors in the room that turn on the lights so its never dark enough to detect the light. I believe the camera is in the smoke detector and there is something glinting in there but it isn't red. I have attached an image. Could this be the camera?

There is a small grey opaque dome in the ceiling of the office where I work. There is a flashing red light inside. I think this is a camera. (In other areas there are obvious CCTV cameras but these are not in grey opaque glass...) Could it be anything else though?
