The hotel fire has been flashing red. Is it a camera?

It's a fire sprinkler, and there will be a flashing red light, which means it works normally. Most hotels have this kind of equipment.

Check whether there is a camera in the room, as shown below:

1. Turn off the lights in the room, draw the curtains, and leave the room in a dark state without any light.

2. Turn on the camera function of the mobile phone and slowly walk around the room, focusing on the dead corner of the room, ceiling, TV, air conditioning and other places where pinhole cameras may be installed.

3. If there is a red dot or a red print on the screen of the mobile phone, that is where the pinhole camera is located.

4. Turn on the light for inspection, dismantle the pinhole camera found, and keep the storage parts well.

Precautions:

1. Press the test button for at least 3 seconds, and it will send out a crisp and loud pulse alarm signal.

2. This means that the detector really works, the LED flashes quickly and gives an alarm at the same time.

3. You can also test the detector by blowing air into the detector cavity. (Do a test once a week to prove the reliable operation of the detector)

4. Do not install the ground with high temperature and humidity, otherwise it will affect the sensitivity.

5. In order to keep the sensor working efficiently, it is necessary to clean the sensor every six months. First turn off the power supply, then gently sweep away the dust with a soft brush, and then start the power supply.
