What do you think? Is there a surveillance camera?

The way to check whether there are surveillance cameras is to use infrared scanners and detectors.

1, using infrared scanner

Infrared scanners can detect the existence of micro cameras more accurately. It uses the reflection principle of infrared rays to detect whether an object has a circuit board. If there is a circuit board, it may be a pinhole camera. When buying infrared scanners, we need to choose products with stable signals and high sensitivity.

Step 2 use a detector

The detector is a special equipment for detecting wireless signals, and can also detect popular pinhole cameras. It has the characteristics of long detection distance, fast scanning speed and fast response speed. Especially for those devices that are not turned on or exposed to the sun, the effect of the detector is particularly remarkable.

Ways to avoid being photographed

1, choose a regular hotel

Choose regular hotels or well-known hotel chains, try to avoid renting houses or private apartments, and better protect your safety and privacy.

Step 2 carry a peep detector

Carrying professional goggles, bugs and other peep detectors can prevent the installation of some pinhole cameras and improve the awareness of prevention.

3. Check the hotel room regularly.

Check the things in the room regularly, and check the holes in the windows, locks and doors. If you find anything unusual, you should report it to the hotel management in time to protect your own safety and privacy.
