How to Detect Hidden Spy Recorders

By Marshal M. Rosenthal

A “Spy” video recorder is so small as to be almost undetectable, even when you are standing right up against it. Detect a hidden spy video recorder hidden in the wall or ceiling of your home by using a LED detector. The LED detector bounces beams of LED light off the spy video recorder’s lens, causing a flashing dot of light to be reflected back. This points out the presence of the spy video recorder. There are a number of LED detectors on the market, all operating in a similar fashion to detect a hidden spy video recorder.

Things You'll Need

  • LED detector

Step 1

Stand at the entranceway of the room or area that you want to search for a hidden spy video recorder. Turn the power switch of the LED detector to the “On” position. Set the “Mode” switch to the “Flash” position.

Step 2

Lift the LED detector up to one eye. Look through the LED detector’s viewfinder while closing the other eye. Aim the LED detector at the extreme, upper left corner of the far wall.

Step 3

Sweep the LED detector from the extreme, upper left corner to the extreme, upper right corner of the far wall. Place the LED detector below the extreme, upper left corner and repeat the process. Continue doing this until the entire wall has been covered.

Step 4

Step into the center of the room or area. Aim the LED detector at the extreme, upper left corner of the wall to your left. Sweep the LED detector from the extreme, upper left corner to the extreme, upper right corner of the wall. Place the LED detector below the extreme, upper left corner and repeat the process. Continue doing this until the entire wall has been covered.

Step 5

Repeat the sweeping process with the LED detector on the wall to your right. Repeat the sweeping process with the LED detector on the ceiling above you.

Step 6

Stop sweeping whenever you see a flashing dot in the viewfinder. Remove the LED detector from your eye. Change the “Mode” setting to “Hold and Flash.” Bring the LED detector back up to your eye. Look directly at the wall or ceiling where you saw the flashing dot.

Step 7

Move the LED detector slowly in a circle until you see the flashing dot again. Walk towards the flashing dot until you are next to the wall or directly beneath the dot if it is on the ceiling.

Step 8

Lower the LED detector. Turn the power switch to the “Off” position. Examine the wall or ceiling (using a ladder) to find the hidden spy video recorder.

Tips & Warnings

  • The LED detector works best at close range, since you must be looking through the viewfinder to see the flashing dot of light.
