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 and
recognition 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 and capturing, 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 identity.

Perimeter 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.

SMD Plus
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

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.
