Answer

You do not write which PICO2000 card you have. If you have the one with one BT878 chip then the method is.

You need 4 thread config files. In all 4 you use the same video_device /dev/video0. But in each thread you have a different input number. Probably 0,1,2,3. Or 1,2,3,4. This makes Motion run in Round Robin mode.

If the card is the expensive one with 4 BT878 chips then Linux should find 4 video devices /dev/video0 ... /dev/video3. And then they all use input 0 or 1.
