Series Overview
This AI network video recorder is a highly cost-effective product,providing functions such as local live view, multi-Screen display,real-time storage on local HDD, fast operation by mouse, and remote management and control. This product is suitable for face detection andrecognition at entrances and exits, and perimeter protection of people and vehicles
Face Detection
Face detection is to detect if there is any human face appearing in the video
This technology adopts a deep learning algorithm to support face detection, tracking, optimization andcapturing, and then output the best face snapshot
Face Recognition
Dahua Face Recognition technology extracts the features of captured faces and compares them with those in face database to recognize the person identityPerimeter Protection
Automatically filtering out false alarms caused by animals, rustling leaves, bright lights, etc. Enables system to perform secondary recognition for the targets. Improving alarm accuracy
With intelligent algorithm, Dahua Smart Motion Detection technology can categorize the targets that trigger motion detection and filter the motion detection alarm triggered by non-concerned targets to realize effective and accurate alarm
AI Search
Support AI seach by metadata of different targets or uploading face pictures to device and comparing them with recorded faces by similarity
Enable operators to quickly and easily search through multi Channels and long duration, efficiently find out when and where a person of interest appeard.
Smart Fan The NVR is equipped with a smart fan to achieve high cooling efficiency
It automatically turns on or turns off according to CPU and ambient temperature
-
The fan is long-lasting and low noise, reducing maintenance costs and improving the user experience
