Extra Info
WizSense Technology
The WizSense series is Dahua's AI-powered product lineup, offering an independent AI chip that enables precise human and vehicle detection. This technology ensures fast and accurate surveillance data processing while significantly reducing false alarms. It simplifies security management, making it accessible to businesses with various levels of surveillance needs.
Face Detection & Recognition
With the ability to manage up to 10 face databases and store up to 200,000 images, Dahua’s face recognition technology helps identify individuals based on their facial features. This is perfect for access control, attendance systems, and enhancing security where knowing who is present is critical. It’s paired with face detection, which ensures high-quality snapshots for more reliable recognition.
SMD Plus
Dahua’s SMD Plus technology ensures more accurate motion detection by filtering out irrelevant movements like wind or animals, allowing the system to focus on human or vehicle targets. This helps reduce unnecessary alarms, ensuring that operators are only alerted when significant events occur.
Perimeter Protection
With perimeter protection, the NVR intelligently filters out unwanted triggers like rustling leaves or animals and ensures that human and vehicle movement is accurately detected. This is particularly useful for larger outdoor environments, like parking lots and property boundaries.
AI Search Functionality
Dahua’s AI Search allows you to search video footage by metadata, making it faster to find specific individuals or vehicles. Operators can upload a face image to compare with recorded footage or search by vehicle plate numbers, improving efficiency when reviewing large amounts of footage.
ANPR and Quick Pick
The ANPR (Automatic Number Plate Recognition) function allows for easy vehicle monitoring, supporting up to 20,000 license plates. It also works in conjunction with Quick Pick technology, which helps security teams quickly identify and retrieve vehicle or person events from SMD.
