*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.
Intelligence
IVS (Perimeter Protection)
Intrusion, tripwire (the two functions support the
classification and accurate detection of vehicle and
human), stay detection, loitering detection
Face Detection (Full
Image)
Face detection; snapshot; snapshot optimization; optimal
face snapshot upload; face enhancement; face snapshot
set as face or one-inch photo; snapshot strategies
(real-time snapshot, quality priority and optimization
snapshot); face angle filter; optimization time setting.
SMD SMD 4.0
Smart Search
Work together with Smart NVR to perform refine
intelligent search, event extraction and merging to event
videos
AcuPick
Uses deep learning algorithms and works with back-end
devices to accurately match targets, such as people and
motor vehicles, and search through live and recorded
videos to quickly locate targets.
AI SSA Adopt deep learning algorithms to adjust the parameters
of the image to suit the conditions.
