Create face databases with up to 20,000 images containing attributes such as gender, age group, and expressions.

Configure the NVR to compare captured faces with the database for identification.

Perimeter Protection and SMD Plus
To enable Perimeter Protection and SMD Plus:

Set up rules for filtering out false alarms and categorizing motion detection targets.
Adjust settings to improve alarm accuracy and reduce unnecessary notifications.

AI Search and Heat Map
To utilize AI Search and Heat Map features:

Use AI search to quickly find videos based on target attributes and event types.

Display crowd density and people appearance probability using the heat map technology.

ANPR by Camera and Quick Pick
To benefit from ANPR by Camera and Quick Pick:

Enable ANPR technology to recognize vehicle number plates with blocklist/allowlist modes.
Quickly pick human/vehicle targets of interest for easy retrieval from SMD events.

Series Overview
Dahua Lite series NVR is easy to install, cost effective and compatible with a wide variety of third-party devices, providing a great solution for small and medium surveillance systems. It is ideal for home safety, supermarkets, warehouses, educational institutions, and financial institutions.

Functions

Face Recognition
Dahua Face Recognition technology extracts the features of captured faces and compares them with that in face database.

Perimeter Protection
Automatically filters out false alarms caused by animals, rustling leaves, bright lights, etc. Enables system to act secondary recognition for the targets. Improves 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
With AI search, operators can search for videos by the attributes of targets and event types, which helps them to quickly and efficiently investigate where and when targets appeared and events took place.

Heat Map by Camera
Dahua 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.
