PIXEL VIDEO SEARCH
The DX8100 allows a user to automatically search any 24-hour period of recorded video for changes in screen pi xels. This feature can be
configured to identify motion events even when motion detection has not been enabled on a camera.
The DX8100 allows sharing of time range search settings between the Thumbnail and Pixel search mode. If you initiate a Thumbnail search, you
can select a preview clip and initiate a Pixel search. The Pixel search mode is based on the same time criteria as the preview Thumbnail clip.
