Extra Info
Compact PTZ Functionality with Pro-Level Control
Don’t let the small form factor fool you—this camera offers true Pan-Tilt-Zoom (PTZ) control, making it ideal for locations where space is limited but dynamic surveillance is still required. It supports up to 8 configurable patrol tours, auto-restores PTZ positions after a reboot, and features smart idle motion behavior to return to a preset or resume a scan path when inactive. Perfect for covering entryways, corridors, or parking areas with one versatile device.
AI-Driven Smart Detection
Equipped with Dahua's AI-powered Intelligent Video System (IVS), the camera supports tripwire and intrusion rules, enabling alerts when a person or vehicle crosses into restricted zones. It also includes Face Detection, which captures and logs facial data for further analysis—ideal for access control points or lobby monitoring.
Efficient Smart H.265+ Compression
With Smart H.265+ technology, the camera optimizes bandwidth by analyzing the scene for motion and adjusting compression accordingly. Features like Region of Interest (ROI) encoding prioritize important areas, helping save up to 70% in bandwidth and storage without compromising critical image quality—especially useful for cloud recording or remote access via mobile apps.
Durability for All Weather Conditions
Engineered for reliability, the camera is rated IP66 for dust and water resistance and IK08 for impact protection. It operates in extreme temperatures from -30°C to +60°C, making it suitable for both indoor and outdoor use, including exposed building exteriors, transport hubs, and warehouses.
