Extra Info
Face Detection – AI-Powered Identity Recognition
Powered by advanced deep-learning algorithms, this camera can detect, track, and capture facial snapshots in real-time. It also gathers facial metadata such as age, gender, expression, and face angle, enabling smarter event filtering and targeted surveillance. Users can configure the system to prioritize high-quality snapshots or filter faces based on orientation, making it ideal for access points, attendance systems, or targeted monitoring in high-traffic areas.
Perimeter Protection – Accurate, AI-Enhanced Alerts
Equipped with Dahua’s intelligent perimeter protection features, the camera supports tripwire, intrusion detection, loitering alerts, and object classification (distinguishing humans from vehicles). These features significantly reduce false alarms by ensuring alerts are only triggered by relevant motion — perfect for securing fences, gates, facility entrances, and sensitive boundary zones where response time is critical.
People Counting – Business Intelligence from Foot Traffic
This feature enables the camera to count people entering, exiting, or dwelling within a specific zone. Useful for gathering operational data in retail stores, events, transportation hubs, and corporate lobbies, it helps organizations monitor crowd density, optimize staffing, comply with occupancy regulations, or generate business reports. Counts can be exported and analyzed daily, monthly, or yearly.
Smart Codec & Video Performance – Streamlined and Flexible
With support for Smart H.265+ compression, the camera efficiently reduces bitrate and storage use while maintaining video clarity. It also offers three simultaneous video streams, allowing for flexible recording and live viewing options — such as sending high-resolution footage to an NVR while streaming a lower-resolution feed to mobile or cloud services.
Reliable Housing – Built to Withstand the Elements
Constructed with a full metal enclosure, the camera is designed for long-term durability. It carries IK10 vandal resistance to endure physical impact and IP67 weatherproof certification to protect against rain, dust, and harsh outdoor conditions. This rugged build ensures stable performance in public spaces, perimeter walls, and exposed environments.
Flexible Storage – Multiple Options for Data Retention
The camera supports hybrid storage configurations, including up to 256GB microSD card storage for local backup, Dahua Cloud, FTP, and NAS (Network Attached Storage). This versatility allows users to tailor recording setups based on their infrastructure — ensuring continuous footage is captured even if the network temporarily fails.
