sweet found it thanks. i will look at ivs, but jsut need movement for mow until i work ivs outOn the NVR its under "Alarm" see screencaps below.
I still recommend you use IVS which is far superior. And make all setting changes on the cameras themselves, not the NVR.

Setup MD on each camera itself. Don’t try and do it on the NVR. Look under “Events”
