Surveillance cameras can be found in public areas and stores as readily as in the buildings of private companies. Protecting one's privacy from a surveillance camera is a difficult proposition because any invasive attack on the camera can be seen as a criminal act or a violation of private property. The most sensible method for blocking a surveillance camera is to to discover its presence by means of an electronic device designed for this purpose. You can then block the surveillance camera from photographing you by the simple act of moving away from its line of sight.
Move the selector switch of the Laser Multi-Sweep Hidden Camera Detector to the "Laser" tab. Bring the device up to your eye and look through the eyepiece as you sweep back and forth across each of the walls of the room or space where a hidden surveillance camera is suspected.
Video of the Day
Repeat the process of sweeping the Laser Multi-Sweep Hidden Camera Detector back and forth across the ceiling and the floor of the room or space.
Stop sweeping the detector back and forth when you see a bright point of blinking light appear in the eyepiece. This is a reflection off of the lens of the hidden surveillance camera.
Change your position relative to where you saw the bright point of light. Sight the detector at the area where you saw the bright point of light. Approach the bright point of blinking light until you come to the hidden surveillance camera.
Move the selector switch of the Laser Multi-Sweep Hidden Camera Detector to the "Audible Detection" tab. Adjust the intensity knob until a green LED begins to flash. Sweep the detector around the room or space in a slow arc as the device senses the radio-frequency (RF) signal that is being used by the hidden surveillance camera.
Move in the direction that causes additional green LEDs to light up from an increased RF signal. Stop moving when the alarm sounds to indicate that a hidden surveillance camera has been found.
