Advanced AI & Intelligent Features

Perimeter Protection (8 Channels)

Automatically filters false alarms caused by animals, rustling leaves, and bright lights. The system performs secondary recognition of targets, dramatically improving alarm accuracy and reducing nuisance alerts.

Face Detection (4 Channels)

Deep learning algorithm supports face detection, tracking, optimization, and automatic capture of the best face snapshots. Detects 6 attributes: gender, age, glasses, expression, mouth mask, and beard. AI search enables filtering by channel, time, and face attributes.

SMD Plus - Smart Motion Detection (8 Channels)

Categorizes targets that trigger motion detection and filters alarms by human or vehicle detection, eliminating false positives from irrelevant movement. Enables precise forensic search by target classification.

People Counting

Accurately tracks and processes human body targets to calculate enter/leave/in-area statistics. Integrates with management platforms to generate comprehensive yearly, monthly, weekly, and daily reports for business intelligence.
