IMO, Motion Detection detects too much, which can cause too many marks on the time line where motion technically happened, but it wasn't anything you were interested in. I second TechBill's suggestion to look at using IVS.
I've had the best luck with drawing a shape around an area (driveway, porch, sidewalk, etc) and using IVS > Intrusion, with both the Crosses and Appears options checked. This will cause an event in your timeline if someone crosses the perimeter of the shape you drew, or if they suddenly appear within the shape (i.e. the camera didn't identify them until after they crossed the perimeter, so to the camera, they just "appeared" within your shape). You can also define minimum and maximum size for the objects. I have to use a minimum size to reduce the false alarms caused by bugs that fly close to the camera at night. For me, IVS gets it right 95% of the time, which is leaps and bounds better than how Motion Detection worked out for me.
). for my nvr I have the problem for irregular date stamps when using date dst. I will try it now with week dst, but i only can see it in october, if it happens again. These are all international models.
