SMD, face detection, face recognition and IVS cannot be enabled simultaneously.
5.11.2 For Pro AI Series
The faces are fuzzily processed to comply with relevant regulations.
AI module provides face detection, face recognition, IVS functions, and video structuring. These
functions take effect after they are configured and enabled. It adopts deep learning and can realize
precision alarms.

Face detection: The Device can analyze the faces captured by the camera and link the configured
alarms.

Face recognition: The Device can compare the captured faces with the face database and then
link the configured alarms.

IVS: The IVS function processes and analyzes the human and vehicle images to extract the key
information to match with the preset rules. When the detected behaviors match with the rules,
the system activates alarms. The IVS function can avoid wrong alarms by filtering the factors such
as rains, light, and animals.

Video structuring: The device can detect and extract key features from the human bodies and
non-motor vehicles in the video, and then build a structured database. You can search any target
you need with these features. For example, you can search any people who wears yellow short
sleeve shirt. See more details in "5.11.1.4 Video Structuring."
