Extra Info

Face Recognition with Metadata Capture

This camera doesn’t just see — it understands. The built-in face recognition engine stores up to 10,000 faces and provides real-time alerts when matches are found. Combined with rich metadata (like gender, age, masks, clothing), it enhances both search accuracy and forensic review.

Auto-Tracking and Perimeter AI

Using deep learning, the camera follows people or vehicles automatically. It can distinguish between humans, animals, and other movements — minimizing false alarms and focusing on real threats.

Long-Range IR + Starlight+

The 500m IR range makes it ideal for perimeter or highway monitoring. Even better, the Starlight+ tech keeps color detail alive well past normal low-light limits, down to just 0.002 Lux.

Smart Wiper + Environmental Protection

A built-in wiper clears rain and dust, triggered by a rain sensor. With IP67 and -40°C to +70°C tolerance, it's designed to keep working in snow, heatwaves, or storms.

PFA Zoom Focus Algorithm

The camera adjusts focus dynamically as you zoom in or out, always delivering a clear and sharp image without the delay or blur that affects most PTZ cameras.
