To configure alarm actions for different groups when faces detected.
Enable Alarm: Tick the checkbox of the group(s) you want to enable alarm function. If the checkbox isn't
enabled, no actions specified for the group such as alarm notifications will be actioned by your NVR.
It is strongly recommended that the "Enable" checkbox for the "Stranger" group remains ticked. This
allows your NVR to save the images of every single face detected, including those that do not match any
existing face profiles to the database. You can use these captured face images later to create or improve
face profiles in the Allow List & Block List groups.
Policy: This setting is non-configurable for the three preset face groups. If a customized group has been
created, you can set the policy of your customized group to either Allow or Deny.
Similarity: Set how closely, in percentage terms, the detected face must match a face profile in the group
to be considered a recognized match. The default threshold is 70%. A higher percentage of similarity will
result in fewer false recognition results.
Alarm: Click the button setup
