How to check whether the hotel has installed a camera?

Check whether the hotel has installed a camera, as shown below:

1, mobile phone scanning code: When entering a room, first turn off the lights and draw the curtains, and keep certain dark conditions. Turn on the camera of the mobile phone and scan it carefully and slowly in every corner of the bedroom. Once the screen of a black mobile phone glows, it is likely to be a small camera.

2, strong flashlight inventory: use a flashlight to check all exposed holes in the room, such as ventilation holes, power plugs, etc. If there is a hidden pinhole camera, you can find the return light according to the direct light of the flashlight.

3, infrared glare flashlight inventory: Because the camera's shape is curved, infrared glare flashlight can have a more prominent bright red back light.

4. Anti-sneak shot APP: This kind of APP is also called camera detector. The key working principle is to detect whether there is a camera connected to the same WiFi.

This kind of APP also has some shortcomings, that is, not all sneak shots are connected to WiFi applications. Some cameras store the candid photos in a memory card for temporary storage, which will not be immediately transmitted to the terminal equipment. At this time, the anti-candid mobile phone software can't be found out.

5, check the electrical law, the current pinhole camera, small size is not easy to find, but relatively speaking, it also consumes a lot of electricity, so it may be placed next to electrical equipment, such as TV sets, air conditioners, electric fans, etc., so it is necessary to carefully check, turn off the power when sleeping, lights and other electrical appliances are off.
