Launched by Dahua Technology, WizSense is a series of AI products and
solutions that adopt independent AI chip and deep learning algorithm.
It focuses on human and vehicle with high accuracy, enabling users to
fast act on defined targets. Based on Dahua's advanced technologies,
WizSense provides intelligent, simple and inclusive products and
solutions.

Series Overview

This AI network video recorder is a highly cost-effective economical
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/exits, and perimeter protection of people and
vehicles.

Functions

1. New User Interface
Local and web interfaces adopt the new UI 4.0 style which caters to 
users habits. Functional modules are divided more clearly and easier to
understand. 

2. Decoding (Smart H.265+/Smart H.264+)
Dahua smart encoding (H.265+/ H.264+) is the optimized
implementation of (H.265/H.264) codec that uses a scene-adaptive
code rate control algorithm, providing more efficiency in the encoding
process and higher video quality, and reducing the cost of storage
and transmission significantly. This NVR supports the corresponding
decoding.

3. SMD Plus
SMD Plus, referred to as Smart Motion Detection Plus, which is an
upgrading version of SMD that greatly improves the alarm accuracy by
loading deep-learning algorithm. It analyzes person and vehicle shapes
based on motion detection and sends alarms only when person or
vehicle intrudes.

4. 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. 

5. Face Recognition
Face recognition is to figure out the captured face with target features,
and compare them with the face database to identify the personnel.
Perimeter Protection
Based on the deep learning algorithm, perimeter protection provides
accurate human and vehicle classification detection. It grealy reduces
false alarms by smartly detecting behaviors such as tripwire and
intrusion according to the detected object in restricted areas (e.g., for
human or vehicle) .
