I built a streaming webcam showing the view from my downtown Oakland apartment in November 2012. I used a Raspberry Pi (Model B Revision 1.0) and the Raspian Wheezy (2012-10-28) image. For the webcam/web server software, I used MJPG-streamer. The problem with MJPG-streamer is that if the images/stream is available on the internet, then anyone can access the software.
Recently my Raspberry Pi began to lose the WiFi connection. In researching various solutions, I disabled WiFi power management on the Edimax EW-7811Un nano-size USB WiFi adapter. That didn’t solve the problem. I switched to Ethernet but the connection still dropped.
The checkwifi.sh script worked great, but then I had an issue with the video stream image oscillating. The image would continually go between light and dark and the only way to stop it was to restart MJPG-streamer.
I’ve had a webcam serving live images using WebCam2000 running on my Macbook. I recently bought a new webcam, a Creative Live! Cam Chat HD (it was cheaper, $25, when I bought it August 2012). The previous webcam I was using, a Vivicam 3350B (I bought it on Woot! for $8.50 in 2005), didn’t have a Windows 7 driver and I was using Windows XP Mode and Windows Virtual PC – it was a little cumbersome.
When the Raspberry Pi was released, I thought it would be a great webcam server. I ordered one from Allied Electronics last July, but they never had stock. When Adafruit started selling them, I bought one.
I made a change to have MJPG-streamer serve a single image instead of a stream. Instead of using http://raspberrypi:8080/?action=stream, I used http://raspberrypi:8080/?action=snapshot. I use a script to reload the page every 10 seconds. In mjpg-streamer.sh, I set FRAME_RATE=”10″ You really don’t see much action unless it’s windy.
Once the Raspberry Pi was setup, I used puTTY to connect to it, so I can start mjpg-streamer and do other things without having the Raspberry Pi connected to a monitor.
