Face Recognition = Face Capture + Face Comparison
If the face capture is performed by AI2 cameras, we will have face recognition in X channels, where X is the number of -XFACE containing your reference. To make a face comparison, a face capture is required, so it is important to know the number of channels that the recorder has available to make face capture.
