Intelligence

IVS (Perimeter Protection)

Tripwire; intrusion (support the classification and accurate detection of vehicle and human)

SMD 4.0

Less false alarm, longer detection distance

Smart Search

Work together with Smart NVR to perform refine intelligent search, event extraction and merging to event videos

Quick Pick

With AI NVR, quickly pick up the human/vehicle targets that users are interested in from SMD events

AI SSA

Adopt deep learning algorithms to adjust the parameters of the image to suit the conditions.
