Thanks for the replay. I am not behind a window but the distance is probably over 20ft. It makes sense since it records movement only at the point where the object is nearest to the camera.
But I still do not get the regular "video detection" to move. If I choose to disable PIR go choose both video detection and PIR in the Motione Detection menu I still have to choose in "Events" menu, to choose between PIR or Video Detection. When I choose Vide Detection, the camera sense movement but does not start to record. But when I choose PIR in the Event Menu the camera detects movements and start recording. But it does not record the three seconds before the movement.
