Extra Info
Starlight+ Technology – Superior Low-Light Clarity
Equipped with a high-sensitivity image sensor, this camera delivers clear, full-color video in extremely low-light conditions, down to 0.005 lux. It’s ideal for environments where lighting is limited but color detail is still critical, such as alleys, car parks, or perimeter zones at night.
PFA (Predictive Focus Algorithm)
Dahua’s Predictive Focus Algorithm (PFA) maintains fast and precise autofocus even during zoom adjustments. Whether the subject is moving or you're adjusting the lens remotely, the camera delivers sharp, uninterrupted video at every zoom level—especially useful in active surveillance zones.
Auto-Tracking – Intelligent Target Following
When motion is detected, the camera can automatically lock onto and follow a person or vehicle across its field of view. Based on preset rules, it dynamically adjusts pan, tilt, and zoom, making it perfect for live monitoring or incident tracking in open areas or long corridors.
AI-Powered Perimeter Protection
With smart tripwire and intrusion detection, the system uses AI classification to distinguish between humans, vehicles, and irrelevant motion like animals or trees. This ensures accurate alerts and reduces the burden of false alarms in sensitive or high-traffic environments.
Smart Compression (H.265+)
Utilizing H.265+ intelligent encoding, the camera reduces video file sizes by up to 70% compared to traditional formats—helping lower storage costs while retaining high-quality video for forensic review or long-term retention.
Built-In Cybersecurity
Security features include:
- Encrypted video transmission
- Secure boot to prevent tampering
- User account locking and access control
These protections help safeguard the device from unauthorized access and cyber threats, making it suitable for enterprise-level installations and data-sensitive applications.
