Camera detector

  1. Jun 10, 2015 #1
    How does a camera detector work? For example inside a room.. how does the equipment tells whether there is a hidden camera with ccd or cmos sensors recording video of you? Does it scan for the ccd/cmos presence or it absorbing the photons or does the detector send laser in every millimeter of the room and scan for uniform arrays in the ccd/cmos?

    A camera detector in the sense of something that detects the presence of a camera? I know of no such device.

    Hidden camera app...

    Video says it looks for reflections from the lens and works even if the camera is off.

    Edit: Google can also find camera detectors that emit pulses of light designed to reflect off the camera lens back to the detector.
