When the mobile phone is connected to the computer, USB devices and webcams will appear. What's the webcam for?

Camera means that your mobile phone has a camera function and can be used as a video! Network camera is an intelligent product with independent IP address and embedded operating system to realize network monitoring. It can be directly connected to the network through local area network, DSL connection or wireless network adapter. The network camera includes lens, filter, image sensor, digital compression controller and embedded operating system. The new webcam can also be equipped with other more advanced functions, such as dynamic monitoring.

Composition

The network camera first collects images (these images can be regarded as composed of light in different bands), and then converts them into photoelectric signals. These photoelectric signals are converted from analog state to digital mode by the network camera, compressed and transmitted to the network.

A camera lens focuses an image on an image sensor (CCD). Before these images reach the CCD, they must pass through a filter. This process will filter out some infrared light so that only the right light can be displayed. The CCD then converts this information, which consists of optical signals, into electrical signals. Then, these electric signals are converted into digital signals and transmitted on the network.

Your mobile phone is similar to mine. In fact, these problems are not your mobile phone, but your computer. When a USB device on the computer is incompatible with the mobile phone, it can't be connected, that is, the mobile phone can't be used as a mobile hard disk! Usually there will be a prompt to connect the device under the taskbar. You can disconnect the interface you are using and use another interface. You got it? Take a good look at it next time,

In addition, your mobile phone can't be turned off when connected to the computer (if you want to exist in the form of a disk) like other people's mobile phones. After turning it off, it will become just a charging method, which is a common problem! -go back and read the instructions much more clearly than what I said here, DEBA·DEBA! However, it means that there is generally no such thing. Let's continue to listen to me!

Generally, when connecting to a computer, if it is used as a disk, it should be the first one, so that songs, materials and so on can be saved. Catch the rest yourself, and experience will tell you the truth! Good luck!
