Separate stream for motion detect

I’m considering switching to Blue Cherry because the VMS I currently use has some problems. I tried out BC but couldn’t find a way to give the motion detector a different (lower resolution) stream. This is something my current VMS allows. Does BC have this feature? Where is it hiding?

We have a feature in development, separate stream for live view. But motion detection is performed on the main stream. Stream can be rescaled to lower resolution before applying motion detection, Devices, Settings-> Motion detection settings->Frame downscale factor, please select Experimental motion detection to make it work
