Intelligent Features

IVS Perimeter Protection

• Tripwire detection

• Intrusion detection

• Fence-crossing detection

• Loitering detection

• Abandoned and missing object detection

• Fast-moving detection

Face Detection

Supports face detection, optimisation and high-quality face snapshot capture. The camera can detect facial attributes and expressions, enhance captured face images and generate customised face cutouts.

Supported snapshot modes include:

• Real-time capture

• Quality-priority capture

• Preferred image selection

WizTracking

Automatically tracks detected targets and records detailed movement trajectories.

SMD 4.0

Uses intelligent human and vehicle classification to reduce false alarms caused by irrelevant movement.

AcuPick

Works with compatible backend devices to accurately match people and motor vehicles across live and recorded footage, allowing targets to be located quickly.

Auto Patrol

When an IVS rule is triggered, the camera rotates to the target position and continues patrolling according to its configured presets.
