These are typically small handheld devices that fit in a pocket or purse. They send out a laser while you look through the special viewfinder. If the laser detects a hidden video camera lens (even less than 1 mm in size), the lens “glows” through the viewfinder, like cat eyes glowing in car headlights.
These detectors are especially useful for locating cameras at a further distance or cameras that may not be transmitting wirelessly (not sending an RF signal), but instead are recording to an internal DVR.
The ad for this one reads: With the flip of a switch, the Laser Hidden Camera Finder Pro allows you to locate all sorts of cameras by simply looking through its lens. Just look through the magnified viewing port to pinpoint the locations of any hidden camera lenses up to 50′ away. Under 4” long, it’s the perfect size to drop in a bag so you can always know when someone has an electronic eye on you.
