How to distinguish smoke from cameras? The most direct way is to see if the red dot is a camera.

There is a difference between smoke and a camera. Friends with strong security awareness will definitely worry that it is the camera that flashes the red light in the hotel instead of the alarm, which will reveal their privacy.

The most direct way to distinguish smoke from cameras

1. If it is a smoke detector, it will work normally and blink every 5~ 10 second, but the camera does not have this function and will not blink all the time.

2. If you look at its appearance carefully, you will find a difference. Generally speaking, smoke detectors are fully enclosed, with only one square sensing window. But the camera is surrounded by perspective windows, surrounded by black wire, mainly for the convenience of monitoring.

3. From the comparison of internal power lines, it can be found that smoke detectors generally have four lines, and these four lines are similar. But the camera has only two wires, one is the power cord and the other is the video output plug.

Will not be installed on the lamp. Monitoring on the road is generally installed in conspicuous places to show the deterrent effect, such as telephone poles.

Whether the camera depends on whether there is a lens or not, there are only sensors! Generally speaking, many cameras installed in hotels will not be seen by you except for normal monitoring, including some infrared sensors, which are the red dots you mentioned.

The probe with a red dot in the middle is a camera. The red dot is not only a sign of electrification, but also an infrared sensor. Generally, it is not easy to see during the day, but it can be seen clearly at night.

There is a red dot after the hotel turns off the lights. Could it be a camera?

If it is a camera, the red dot will always be on. Generally, the red light emitted by the camera is the infrared light of the infrared LED next to the lens, which provides illumination for the lens in a dark environment.

If you can't see the red dot when you turn off the lights, continue to turn off the lights and rest.

The red dot is not necessarily a camera, and the red led also emits red light. Bright red light is light from red LED, and dark red light is light from camera.

After turning off the lights, you look around with the camera on your mobile phone to see if there are any bright spots. If there is, it's from the camera, but without the camera, it doesn't mean there is no camera.
