How to detect if there is a camera in a hotel room

1. The method of checking the camera is very simple, because the pinhole camera can work at night, and in order to take the required picture, it requires the assistance of infrared rays. So after entering the room, close the curtains, turn off the lights, and use your mobile phone to scan every corner of the room. If there are red dots on the camera screen, turn on the lights to check whether it is a camera.

2. Cameras are usually installed in bedrooms or bathrooms. Although you can’t be 100% sure about all of this, you should still check these places. Start simple: think about where to place your camera. To find something out, you have to think like the other person. So, you should check the room and choose those angles that are best for viewing. Pay special attention to the upper corners of the bedroom, walls near the bathroom, and the bed, etc.

3. Use the wifi function of the mobile phone to test whether there is a pinhole camera. Turn on the WIFI function of your phone to search for nearby hotspots. If the name of a hotspot with the strongest signal is a0.c0.a1, etc., take your phone and walk out of the room about 20 meters to see if the signal weakens. If so, Note that there is probably a wireless pinhole camera.
