Face Recognition is a video analytic that offers facial recognition, event triggering, and alarms in Aimetis Symphony.
You create a profile, add images of the individual's face to that profile, and set whether the profile is blocked or allowed. When Face Recognition matches a face in video to a face associated with a profile, it can trigger an event.
If the Face Recognition icon is not visible in the toolbar, customize the toolbar to make it visible.
In the Client interface, a blue square surrounds a tracked face and a red square surrounds a tracked face that triggers an alarm.
You can configure Face Recognition in the Server Configuration interface.
1. Add a camera as per instructions in Device - Network (IP) Cameras or Video Servers.
2. Select a license from the Analytic License Requested list and click Update License.
