What is the noise in Xiaomi monitoring?

There is noise in Xiaomi's monitoring for the following reasons:

1. The camera sound of the mobile phone is turned on. When the camera sound of the mobile phone is turned on, the camera will make a shutter sound. The solution is to turn on the camera settings of the mobile phone and turn off the camera sound in the settings.

2. There is something wrong with the connection between the mobile phone camera and the mobile phone motherboard. The camera doesn't open properly, resulting in a hissing sound. At this time, you need to go to the after-sales maintenance service center to repair and check the camera with relevant certificates such as mobile phones and mobile phone purchase invoices.

3. There is an error in the mobile phone system. After the mobile phone system error, the camera can't turn on normally and make a sound. At this time, the solution is: turn it off and then on to see if the camera is abnormal, or reset the mobile phone to solve the problem of mobile phone system error.
