e-PTZ

IVS (protecție perimetrală)

Intrusion, tripwire, fast moving (the three functions support the classification and accurate detection of vehicle, animal and human); loitering detection, people gathering, parking detection, privacy protection. Supports long- distance mode. Supports self-learning, it filters out false alarms.

Detecție față

Face detection; track; snapshot; snapshot optimization; optimal face snapshot upload; face enhancement; face exposure; face attributes extraction including 6 attributes and 8 expressions; 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; privacy protection

Recunoaștere facială

There are two modes: General mode and counting mode. General mode: Face detection; snapshot; snapshot optimization; optimal face snapshot upload; face enhancement; face exposure; face attributes extraction including 6 attributes and 8 expressions; face snapshot set as face or one inch photo; snapshot strategies (recognition priority and optimization snapshot); face angle filter; optimization time setting; privacy protection. Supports adding 5 group face databases; registering person one by one or in batches; setting face similarity; and supports face comparison with the face database containing up to 200,000 face pictures. Counting mode: Offers advanced customer counter, filters out specified faces from the face database, and exports reports both before and after removing duplicate faces.

Detecție echipament de protecție (PPE)

Triggers alarms when the detected object matches or does not match all of the configured attributes (workwear, safety helmet, cap, face mask, apron, gloves, shoe covers, boots, safety vest, and seatbelt). Supports self-learning, it detects the different colors and styles of workwear. Supports privacy protection.
