Hello all,
I've seen many people searching for motion detection plugin and I'd like to suggest you motionEye ( if nobody did before ) at this webpage:
https://bitbucket.org/ccrisan/motioneye/wiki/Home
I'm testing it on my raspberry and seems really awesome; both support for usb webcam and netcam.
Not yet tested on OMV as don't know if packages required could cause some problem.
Requirements are:
enjoy all
