ssh reverse proxy Raspberry Pi + motion, realizing public network by remote video surveillance

Note: This article is part of the public network remote monitoring needs the cloud server has a public IP were ssh reverse proxy.

First, by means of video surveillance within the network to achieve motion

• ready
  • Plug camera, and then enter the ls /dev/video*command to check whether the identified camera
• Installing motion
  • motion linux is open source, raspberries come in use in sudo apt-get install motionorder to install, easy to install.
• Modify motion configuration
  • Common configuration and meaning

  # Start in daemon (background) mode and release terminal (default: off)
  # 在后台运行。设置为off将在前台运行
  daemon on
  # Videodevice to be used for capturing  (default /dev/video0)
  # for FreeBSD default is /dev/bktr0
  # 视频设备，刚才ls /dev/video*看到的
  videodevice /dev/video0
  # Image width (pixels). Valid range: Camera dependent, default: 352
  # 图像宽
  width 320
  # Image height (pixels). Valid range: Camera dependent, default: 288
  # 图像高
  height 240
  # The setting for keep-alive of network socket, should improve performance on compatible net cameras.
  # off: The historical implementation using HTTP/1.0, closing the socket after each http request.
  # force: Use HTTP/1.0 requests with keep alive header to reuse the same connection.
  # on: Use HTTP/1.1 requests that support keep alive as default.
  # Default: off
  # 开启KeepAlive功能
  netcam_keepalive on
  # Output 'normal' pictures when motion is detected (default: on)
  # Valid values: on, off, first, best, center
  # When set to 'first', only the first picture of an event is saved.
  # Picture with most motion of an event is saved when set to 'best'.
  # Picture with motion nearest center of picture is saved when set to 'center'.
  # Can be used as preview shot for the corresponding movie.
  # 禁用自动拍照保存的功能
  output_pictures off
  # Use ffmpeg to encode movies in realtime (default: off)
  # 禁用自动拍摄视频保存的功能
  ffmpeg_output_movies off
  # The mini-http server listens to this port for requests (default: 0 = disabled)
  # 视频监听的端口，默认8081
  stream_port 1001
  # Quality of the jpeg (in percent) images produced (default: 50)
  # 图像质量
  stream_quality 50
  # Output frames at 1 fps when no motion is detected and increase to the
  # rate given by stream_maxrate when motion is detected (default: off)
  stream_motion on
  # Maximum framerate for stream streams (default: 1)
  # 帧数8，需要先把上面的选项改成on
  stream_maxrate 8
  # Set the authentication method (default: 0)
  # 0 = disabled
  # 1 = Basic authentication
  # 2 = MD5 digest (the safer authentication)
  # 改成1，增加授权验证，访问需要输入密码
  stream_auth_method 1
  # Authentication for the stream. Syntax username:password
  # Default: not defined (Disabled)
  # 设置用户名username和密码password
  stream_authentication username:password
  # Restrict stream connections to localhost only (default: on)
  # 改成off允许外网访问视频
  stream_localhost off
  # TCP/IP port for the http server to listen on (default: 0 = disabled)
  # WEB控制台监听的端口，默认8080
  webcontrol_port 1000
  # 改成off允许外网访问web控制台
  webcontrol_localhost off
  

  • Must be modified daemon onare: webcontrol_localhost off, . The default configuration may have significant Caton, then adjust their own parameters. Finally, the effect can be very smooth.
  • Use sudo motioncommand to enable motion
  • Use sudo killall -TERM motioncan turn off the motion
• test
  • sudo motionAfter input in the browser ip:你设定的端口号（默认8081）to view real-time monitoring. Such as: 192.168.137.30: 8081.
  • Note: At this point only the internal network access.

Second, to achieve the public network remote video monitoring via ssh reverse proxy Raspberry Pi

• Raspberries come in
  • ssh -CqTfnN -R 0.0.0.0:12345:localhost:8081 ubuntu@yourserver(Test.server cloud server is a domain name or ip)
  • This connection is established yourserver 12345 a local port to the port 8081 of pi, after yourserver can use this communication port and a pi.
• On the server
  • ssh -fCNL "*:12345:localhost:12346" ubuntu@yourserver
  • 12346 listens to build a port other client's request, when the 12346 port receives data when the data is transferred to port 12345, then 12345 ports that connect to port 8081 Raspberry Pi to achieve a "proxy" effect. When a browser to access the cloud server port 12346, the equivalent access port 8081 Raspberry Pi, enabling real-time monitoring public network.
  • This method of using the ssh reverse proxy can also achieve the public network remote control Raspberry Pi.
• test
  • After Raspberry Pi open motion, entered in the browser 服务器ip:服务器设置的监听端口（本例为12346）to see motion video.
  • Note: Due to the speed limit, the video may Caton. At this point modify motion configuration, reduce the size, frame rate, image quality, etc. can be eliminated Caton.
