Create a file named cameras.config containing the following:
<camera1_name> <camera1_url>
<camera2_name> <camera2_url>
...
<cameraN_name> <cameraN_url>
You may need to add a username and password to the url, i.e.:
camera1 rtsp://username:password@10.0.0.5/11
Then run:
./record.py
Currently this is only configurable by modifying record.py.
