|Experimenting with the use of webcams for security.|
A USB webcam of the model "Logitec Quickcam Zoom" is also available for this project. Using VLC you can access it's output using this command:
vlc v4l2:///dev/video0 --fullscreen
A Ethernet camera of type TP-Link TL-SC3130G is permantently installed in the bar area of Den Bunker. Accessing this camera can be done from any browser, we in the space just browser to http://10.98.71.25/. Direct access to the streaming images is also available through VLC (and other players). This camera supports two different types of video-streams although not both simultaneous.
For a MPEG-4 videostream "Settings > Basic > Camera > RTSP" has to be set to ON in the web-interface.
vlc rtsp://10.98.71.25:8554/video.mp4 --noaudio --fullscreen
To be able to enable the Motion JPEG stream on this camera you have to set "Settings > Basic > Camera > RTSP" to OFF.
vlc http://10.98.71.25:8070/video.mjpg --fullscreen
To do the aggregation, capture and motion detection of video data we plan to use Zoneminder. At the moment I can configure both camera's to work in Zoneminder but not at the same time.
On Ubuntu 10.10 Zoneminder can be installed straight from the repositories.
sudo apt-get install zoneminder
After this you should be able to load zoneminder at http://localhost/zm. If not you may need to change the following lines in the file /etc/apache2/sites-enabled/000-default. Find the line:
and change it to read
Similarly change the line:
After these changes you need to restart zoneminder ans apache.
sudo /etc/init.d/zoneminder restart sudo /etc/init.d/apache2 restartNow zoneminder should be available at http://localhost.
For the USB camera the following settings were used:
Path: /dev/video0 Capture: Video 4 Linux 2 Channel: 0 Format: PAL Palette: YUV420 Width: 320 Height: 240
For the network camera using Motion JPEG:
Protocol: HTTP Method: Simple Name: 10.98.71.25 Port: 8070 Path: video.mjpg Colours: 8 bit greyscale Width: 640 Height: 480
This link was very useful setting up this system:
