Enable video streaming

Video streaming is diabled by default. To enable video streaming, edit /etc/config/mjpg-streamer and change option enabled "0" to option enabled "1" 
Note: Microsoft LifeCam HD-5000 support resolution up to 1280x720,  I'm using option resolution "1280x720" for my case. 

config mjpg-streamer core
         option enabled "1"
         option device "/dev/video0"
         option resolution "640x480"
         option fps "5"
         option www "/www/webcam"
         option port "8080"

Restart the router, you are ready to stream the video.
 
  • start on boot
    /etc/init.d/mjpg-streamer enable
  • start mjpg-streamer right now
    /etc/init.d/mjpg-streamer start
  • Stop mjgp-streamer
    /etc/init.d/mjpg-streamer stop
 

Nanavigate to http://192.168.1.1:8080, you should see the following screen
