4.6 Advanced Features
4.6.1 Smart Search
The Smart Search feature refines the loaded video footage based on motion detected within a user-defined region.
To perform a Smart Search, you must first define or “mask” a motion
detection region. To do this, click Show Mask and draw on the playback
image. Any time a clear area is clicked on, the mask is expanded. Alter-
natively, when a masked area is clicked on, the mask is removed. Click
the Smart Search button to perform the search. Once the search is com-
plete, only video frames that contain motion in the masked region will
be loaded for playback.
Note: If there is more than one masked region (i.e. two or more
disconnected masks), the Smart Search will load video frames
that contain motion in any of the regions.
Show
Mask
Shows/hides the Smart Search mask. A mask can only be edited when the Show Mask button is latched on.
Mask
Offers some quick options for modifying masks:
Clear – Erases all masks on the image.
Select All – Masks the entire image.
Invert - Swaps clear and masked areas.
Note: The Show Mask button must be latched on for these options to be available.
Sensitivity
This slider controls the sensitivity of the motion detection algorithm used by the Smart Search function. To the left is
less sensitive, requiring larger change in motion; to the right is a more sensitive, detecting smaller movement.
Smart
Search
Performs the Smart Search. Video frames that do not contain motion in the masked regions are removed from the
loaded footage. Use the buttons to skip back/forward to the next Smart Search frame.
Reset Removes all Smart Search masks and restores the originally loaded footage.
Visual
Track
When enabled, the Visual Tracking feature tracks moving
objects by the placement of white corners around the
object.
Analytics Displays a menu where Video Analytics information can be overlaid on the playback footage.
