I have to go to the hotel.

When couples stay in a hotel, many people suggest playing with their mobile phones before entering the room, mainly because there may be cameras in the room. Look for it with your mobile phone first to avoid revealing privacy. Many criminals will secretly install cameras in hidden places in hotels, and some people use high-tech means to record indecent videos. Even hotel managers can't completely eliminate this phenomenon. So someone reminds you to play with your mobile phone before staying in a hotel, and you should take the advice. This is for your own good.

In order to ensure our own safety and keep our local privacy from being leaked, we should learn more preventive measures. There are many ways to detect the camera when you check in at a hotel. Simply put, the infrared wavelength on the camera is invisible to the naked eye, which provides a light source for the camera to work in the dark, while the camera on our mobile phone has a silicon detector. In this way, we can easily find the camera. Although this detection method is not 100% effective, we can still find some cameras, which can provide some guarantee for our safety.

The specific way is to close the curtains after entering the hotel room and turn off all the lights to make it a closed space with dark light. Turn the whole room into a dark state, then turn on the video function of the mobile phone and scan every place in the room at close range. If you find abnormal light on the screen, you should immediately check whether there is a camera hidden behind. For example, there is a TV across the bed and a vase on the TV cabinet. In addition to these places, the hotel's bathroom water heaters and mirrors also need to be inspected.

Pay more attention to check every corner of the bathroom. After all, your own safety is more important, so you should pay attention. Mobile phone has become an important communication tool in our daily life, but I didn't expect it to play such a role when staying in a hotel. Try it every time you stay in a hotel. Not only couples need to check, but ordinary people also need to check whether there is a camera for their own safety.
