In normal lighting conditions, LED light is not detected. Nevertheless, with proper darkness, you will be able to detect this type of light. It is also necessary to consider that different clocks that incorporate the hidden camera do not have the same design. (1)

This means that some clocks may include a hidden camera without a flashing LED light. It is a good way to start detecting and checking for a hidden camera in your clock.

2. Using a Flashlight

The difference is that a flashlight can be a much more efficient way to check your clock for a hidden camera. It is important to detect any kind of reflection when using the flashlight.

A flashlight used in the dark is more than enough to be able to detect any kind of reflective surface or any kind of small illumination. The reflective surface should be very small and round like a camera lens. When the reflective surface is much larger than a simple camera lens it may not be a hidden camera.

3. Making a Phone Call

The cell phone signal when making the call will have some minimal interference as well as static noise. It is advisable to walk around the room keeping the call active at all times. To check if your clock has a hidden camera, a phone call should be made next to the clock.

To correctly detect the interference, the person could approach and move a few meters away from the clock. As the cell phone with the active call is close to the clock the interference should intensify.

The opposite situation should happen when the person moves away and continues to talk on the phone. The interference should decrease if there is a hidden camera in the clock.

4. Bug Detector
