Extra Info
ePTZ (Electronic Pan-Tilt-Zoom)
Electronic PTZ allows the camera to digitally pan, tilt, and zoom within its field of view — enabling it to track multiple targets or zoom in on specific areas of interest without physically moving. This smart feature is especially valuable for real-time threat monitoring, offering the benefits of PTZ functionality at a lower cost and with fewer mechanical parts, reducing long-term maintenance.
Smart Motion Detection (SMD) 3.0
SMD 3.0 is Dahua’s next-generation motion detection powered by AI. It filters out irrelevant motion such as rustling leaves, small animals, or shifting shadows, focusing only on events triggered by people or vehicles. This greatly reduces nuisance alarms and enhances the accuracy and reliability of surveillance alerts.
Starlight Technology
With exceptional low-light sensitivity down to 0.001 lux, Starlight Technology allows the camera to capture vivid, full-color images even in near-total darkness. Unlike traditional IR-only night vision, this ensures enhanced clarity of faces, clothing, and objects at night — ideal for environments with minimal lighting like alleys, side entrances, or large yards.
AI-Powered Perimeter Protection
This camera supports intelligent perimeter monitoring features such as tripwire and intrusion detection. Backed by AI, it can distinguish between humans and vehicles, significantly reducing false alarms caused by animals, weather, or lighting changes. It’s ideal for securing boundaries, entry points, or sensitive zones with high accuracy and minimal manual intervention.
Smart Compression (H.265+/H.264+)
To optimize storage efficiency and reduce network load, the camera employs Smart H.265+ and H.264+ compression. These technologies maintain high image quality while using intelligent scene analysis to compress static or low-activity regions more effectively, saving significant storage space in large-scale deployments.
Comprehensive Cybersecurity Features
Security is built-in from the ground up with advanced features such as trusted execution environment (TEE), secure boot processes, encrypted firmware, HTTPS for secure web access, and strong user authentication protocols. These protections ensure your video data and device configurations remain safe from tampering or unauthorized access.
Q&A
