Product Features

4MP WizColor Full-Color Imaging

The 4MP 1/1.8-inch CMOS sensor combined with WizColor technology captures clear, full-color video in near darkness, ensuring reliable identification without reliance on constant white-light illumination.

Pan and Tilt Coverage with Auto Tracking Lite

The pan-and-tilt mechanism provides wide-area coverage with smooth movement, while Auto Tracking Lite automatically follows detected human or vehicle targets to keep them within the frame.

WizSense AI with SMD 3.0

Advanced deep learning algorithms enable accurate human and vehicle detection, significantly reducing false alarms from irrelevant motion such as animals or environmental changes.

Intelligent Perimeter Protection

Supports tripwire and intrusion detection with precise target classification, making it suitable for securing entrances, perimeters, and restricted zones.

Active Deterrence with Light and Sound

Built-in warm light warning and speaker support visual and audible alerts, including customizable voice messages, to actively deter intruders before incidents escalate.

Two-Way Audio Communication

Integrated microphone and speaker enable real-time two-way communication, allowing users to warn intruders or interact with people on-site directly through the camera.

Efficient Video Compression

Support for Smart H.265+ and Smart H.264+ encoding reduces bandwidth and storage requirements while maintaining high image quality.

Durable IP66-Rated Design

The weather-resistant housing ensures reliable outdoor operation, protecting the camera from dust, rain, and harsh environmental conditions.
