Python implements remote camera screenshot function

Mar 11, 2017 am 10:37 AM

这篇文章主要介绍了python操作摄像头截图实现远程监控的例子,例子中包含了控制摄像头、写入Windows注册表方法等,需要的朋友可以参考下

最近用python写了一个远程监控的程序,主要功能有:
1.用邮件控制所以功能
2.可以对屏幕截图,屏幕截图发送到邮箱
3.可以用摄像头获取图片,这些图片上传到七牛
4.开机自启动

            camera_capture()
Copy after login

 

注意:
1.我的发送邮箱是sina邮箱,接收邮箱是qq邮箱,这样做是因为微信可以绑定qq邮箱。
2.accept_mail()监听的邮箱是自己的接收邮箱,就是我用的qq邮箱
3.当监听到screen时,开始屏幕截图并发送到邮箱,由于监听的是最新的邮件,当图片发送带邮箱时,获取的邮件主题不是screen了,应该会停止截图,最后只会截取一张图片,继续保持监听状态。但实际由于网络的原因,发送的邮件会有延迟,所以,实际截取的图片会有很多张
4.当监听到camera时,会用摄像头截图,如果把while i<10,改成i=1,会让摄像头一直截图,并使其他命令失效,所以我i<10,就是每获取一次命令,截图10张
