Algorithm Management; Face Picture Comparison; Face Grading Configuration - HIKVISION iDS-6700NXI-I/FA Series User Manual

Auto Update
After a round of training is completed, the device would automatically update the algorithm
according to the preset time.
Note
● Training Task is enabled by default.
● Enabling Training Task would occupy one engine, so the number of available channels for smart
analysis may decrease.
● When the algorithm is upgrading, the number of false alarms may currently be increased.

7.3.2 Algorithm Management

If the video scene is changed, or the alarm accuracy is not as good as it used to be, you can restore
it to previous version or the original version.
Go to Smart Analysis → AI Training → Algorithm Management to manage algorithm.

7.4 Face Picture Comparison

The device supports the face picture comparison alarm and face capture for the connected camera
based on face recognition feature.
Go to Smart Analysis → Engine Settings → Engine Configuration. Configure at least one engine
usage as Facial Recognition. Refer to Engine Configuration for details.
Note
The chapter is only available for certain models.

7.4.1 Face Grading Configuration

Face grading is used for face picture selection. According to pupil distance, tilt angle and pan
angle, it only uses face pictures which satisfy grading requirement for analysis. Larger pupil
distance, smaller tilt and pan angle, better it would be for analysis.
Steps
1. Go to Smart Analysis → Engine Settings → Face Grading.
