Example of using python to remotely monitor camera screenshots

This article describes how to remotely monitor a python camera. The example includes the control camera and the method for writing data to the Windows registry, you can refer to a remote monitoring program recently written in python. The main functions are as follows:
1. Use email to control the functions
2. You can send the screen to your mailbox
3. You can use a camera to obtain images. These images are uploaded to qiniu.
4. Auto Start

The Code is as follows:

Camera_capture ()

Note:
1. My sending mailbox is sina and the receiving mailbox is QQ. This is because I can bind a QQ mailbox.
2. The accept_mail () Listener's mailbox is my own receiving mailbox, which is my QQ mailbox
3. when the screen is listened to, the screen starts and is sent to the mailbox. Because the latest email is listened to, when the image is sent with the mailbox, the obtained Email Subject is not screen and should be stopped, at last, only one screenshot is taken and the listener continues. However, due to network issues, the sent emails may be delayed. Therefore, there may be a lot of captured images.
4. when I listen to camera, the camera will be used. If I change while I <10 to I = 1, it will keep the camera and invalidate other commands, So I <10, 10 commands are obtained each time.
