Device node for external camera
 

Hi!

I have an external IP camera which serves video at
http://192.168.1.20/mjpeg.cgi. Actually I have 5 of them with different
IPs, but that's beside the point... :-)

I want to use the program "motion" for motion detection. However it
requires input from a device node such as /dev/video0.

How can I create such a device node so that it corresponds to my IP camera?

I would first check if yoru device is supported by "motion" and given that
your are using a network camera, this may help:

Just uncomment netcam_url string and assign it a value in ~/motion.conf
It's a great program - though masking can be a little fiddly. Enable the
web interface and you'll find the documentation is more accessible
through it.
You can also edit through the browser interface - default is
http://localhost:8080 - there's a thread for each camera (I run several)
NOTE: you can change the http options in motion.conf so that http is
available externally (don't forget uncomment the password option).
You'll also need to be in the motion group.

Cheers

Device node for external camera
 

Thank you! So how do I specify multiple cameras in the same conf file? Never mind, with what you told me I can look it up in the docs.
