Face Recognition:
Dahua's Face Recognition technology extracts features from captured faces and compares them with a database to identify individuals.

Perimeter Protection:
This feature filters out false alarms caused by animals, rustling leaves, or bright lights. It allows for secondary recognition of targets, improving the accuracy of alarms.

SMD Plus:
Dahua's Smart Motion Detection (SMD) technology uses an intelligent algorithm to categorize targets and filter out non-relevant motion detection alarms, resulting in more precise and effective alerts.

AI Search:
AI Search allows for the quick identification of targets by searching metadata or uploading and comparing face pictures with recorded images. This feature facilitates efficient multi-channel and long-duration searches to pinpoint when and where a person of interest appeared.

Heat Map by Camera:
Dahua’s heat map technology visualizes crowd density and the probability of people appearing in specific areas. It uses color coding to display crowd status, offering statistical insights into the number of people present over time and space.
