Simple Detect hidden cameras for video surveillance

Posted by Spokane 2600 Webmaster at May 02. 2016

all night vision cameras share a common “flaw” of infrared lights in the lenses. Although you can’t see infrared light with your eyes, it is what allows a camera to keep up surveillance in the dark. If you think there might be small hidden cameras in your house or business, then you can use your smartphone to find out.

When a room is dark, he suggested turning on your smartphone camera and slowly scanning the room. If there are hidden cameras, then Polstra said you will be able to see the flare of infrared from the covert camera through your phone’s display. If you don’t have a smartphone, but do have a digital camera, then you can use that to look for evidence of being under video surveillance.

He had additional tips for detecting wireless cameras such as using an app to detect a wireless ad hoc network that the surveillance devices are using to communicate with each other. He called airodump-ng an “easy way” to search for wireless cameras, but listed more sophisticated methods such as using Python. Although he proposed several moderately expensive methods, he said an inexpensive solution would be to use a BeagleBone-based system.
