What's flashing red in the hotel room?

It's a fire sprinkler. It's flashing red, which means it's working normally. Generally, hotels have such equipment, and so does our office building. At the end of next year, there will be a building management to check, use pipes to pump, sprinklers will call the police, and then spray water or foam to extinguish the fire.

How to check whether there is a camera in the room;

1. Turn off the light in the room, turn on the camera function of the mobile phone (don't turn on the flash), and use the mobile phone to circle the room. There is no red dot on the screen, which means the room is safe and there is no pinhole camera. Pay attention to the extremely hidden dead angle.

2, the use of professional dog detection tools, can use the principle of electromagnetic induction, at any time to detect the presence of pinhole or eavesdropping equipment, to prevent, focusing on the inspection of objects facing the bed and some flowers and plants.

3. Avoid the entry and exit of unidentified people. Pay attention to whether the doors and windows are closed when taking a bath, and go in and out of public places. Pay attention to check whether there are suspicious people or inappropriate items around.

4. Turn off the power. Because pinhole cameras consume a lot of electricity, photographers may use the power in the room. You can turn off the main power supply in the room, and the pinhole camera will not work normally.
