*DORI (Detect, Observe, Recognize, Identify) is a
standard system (EN-62676-4) for defining the ability
of a person viewing the video to distinguish persons
or objects within a covered area. The numbers in this
table do not reflect intelligent function distances. For
intelligent function distances, refer to installation and
commissioning manual/project design tool.

classification
Face Detection
Supports face detection, snapshot, and face
enhancement; Supports face cutout: Face, oneinch photo; Capturing strategies include real-time
capturing and quality first.
People Counting
Supports counting the number of people that cross
the detection line, counting the number of people in
an area and queue management. Also, only people
counting that cross the detection line supports the
report function.
