How to check whether it is safe when staying in a hotel?

When a person stays in a hotel, how should he check whether there are cameras and other equipment in the hotel room?

1、

First of all, after entering the hotel, check the overall layout of the room, focusing on whether there are available equipment in the corner, such as monitoring and cameras.

2、

After seeing these corners, we will conduct in-depth inspection and confirmation, block all the light in the room, make the room look like night, turn on the camera function of electronic equipment (more mobile phones), and conduct a three-dimensional and all-round survey of the room. Note: Don't turn on the flash or take photos, just turn on the camera function and view it on the camera screen of the mobile phone.

3、

If you find red or luminous spots on the camera interface of electronic equipment, please note that it may be a pinhole camera. If no abnormality is found, please proceed to the next step for confirmation. (Using infrared principle)

4、

Turn on the broadcast function of electronic equipment, find a program that can be heard clearly, then walk around the room and pay attention to finding some corners. If there is electromagnetic sound, the listening effect is unstable and squeaks appear, please pay attention to the investigation. It is caused by interference, please use the above photography methods for further investigation.

By using the above method, we can check whether the hotel room is safe. I would like to remind you that you must pay attention to safety when traveling, and never try to stay in hotels with particularly low security, because these small hotels may not only lose money, but also have many security risks. .
