How to detect whether there is a camera in a hotel room?

The method for detecting whether there is a camera in a hotel room is as follows:

1, you can turn on the radio of your mobile phone and walk around the room. If there is a camera, the signal of the wireless camera will interfere with the sound quality of the radio, but this can only detect the wireless camera. If it is wired, this method is useless.

2. Turn off all the lights in the room, and illuminate the cameras in sockets, corners, decorative paintings, televisions and other places where cameras are easy to install, and the cameras will reflect light. This is a very simple physical method, but you must pay attention to observe it carefully.

3. After turning off the lights, you can also use the mobile phone camera to see the surrounding dark places, because the dark pinhole camera needs infrared light, and the corresponding red dot can be seen on the mobile phone camera.

The locations where pinhole cameras are easy to hide in hotels are:

Television, router, set-top box hole, smoke alarm, air conditioning outlet, ceiling corners, chandeliers and other hidden places, hanging shadows, wall socket switches. Pay special attention to the alarm clock, speaker, water dispenser, air purifier and other equipment facing the bedside, as well as toiletries in the bathroom and bathroom.

Photographers may hide waterproof cameras in large-capacity shampoo and bath bottles. If residents just squeeze the shower head, they can't find the camera. But if you shake the bottle, you can feel the camera inside.
