NVR4000-AI/ANZ series is a new generation of network recorders that
offers powerful decoding capabilities, and strong bandwidth. It features
high-precision face recognition, perimeter protection, and SMD (Smart
Motion Detection), which can distinguish target vehicles and humans
from other types in real time. When connected with select IPC cameras,
Quick Pick technology becomes available, allowing human and vehicle
targets to be easily searched for and picked out. This network recorder
is not only cost-effective, but also compatible with a wide variety of
third-party devices, making it a great choice for small and medium-sized
businesses.
Face DetectionFace 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 RecognitionDahua Face Recognition technology extracts the features of captured
faces and compares them with those in face database to recognize the
person identity.
Perimeter ProtectionAutomatically 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 PlusWith 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 SearchSupport 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.
Heat Map by CameraDahua heat map technology is used to display the crowd density and
people appearance probability. Export and display the crowd status by
different colors. Generally, the crowd status is the statistics of people
quantity in space and time dimensions.
ANPR by CameraWith deep learning algorithm, Dahua ANPR technology can recognize the
number plate information of vehicles in the image with ANPR cameras.
Support blocklist/allowlist mode, searching target vehicles from recorded
video.
Quick PickDahua Quick Pick technology can enable users to quickly pick up the
human/vehicle targets that they are interested in, which facilitates
retrieval from SMD events.
