With Generate motion data for smart search enabled, the system generates motion data for the images used for motion detection. For example, if you select motion detection on keyframes only, the motion data is also produced for keyframes only.
The extra motion data enables the client user, via the smart search function, to quickly search for relevant recordings based on motion in the selected area of the image. The system does not generate motion data within areas covered by permanent privacy masks, but only for areas with liftable privacy masks.
Motion detection threshold and exclude regions do not influence the generated motion data.
You specify the default setting of generating smart search data for cameras on the Tools > Options > General tab.
