Can I tell zoneminder to switch active camera every n seconds (by opening a different /dev/videoN file or by running a shell command)?
If so, how will motion detection behave when input image suddenly change?
Desired behaviour is to virtualize the channels of one capture device as multiple devices. Reuse last captured frame while the channel is inactive. Skip a couple of frames while switching.
Code: Select all
12fps, switch each second.
