Is there a hidden device in smoke detectors?
Is there a hidden device in smoke detectors? A hidden surveillance camera may be present in the smoke detector giving a clear view and angles of the room without you realizing it. You should look for the lens of a camera. Even if a spy camera has a tiny lens, it will definitely be visible. The lens of the hidden camera is similar to the lens of the mobile phone.
How do you tell if a room is bugged?
Small, discolored areas on wall or ceilings may indicate that a pinhole microphone or small camera has been installed. Switch plates for outlets and light switches that are slightly off-kilter or whose screws are in different positions are a surefire sign that they have been removed and possibly bugged.
