Thanks Wildcat,
first, the official specs of the NVR are mentioning: "4 channel video stream face recognition / 16 channel picture stream face recognition ( with FD camera) "
If I understand correct, I can get either 4 channels of face recognition using "normal" ip cams OR 16 channels of FR using FD cams.
As far as I understand, those cams support face detection and face capture so I can have as many as 16 of them supporting the FR.
That way or another, I do not need more than 4 of the cams to give me face recognition.
Actually, if I'd be lucky, I'd be able to use 3 of them with FR. do not forget that for FR we are talking about the right distance, the right height and I guess also the right angel.
Not experienced as you are, but still, I believe that if you mount a cam "right" to be used for FR, you compromise much more than "just" ANPR.
I guess that in most cases, if you want the FR to work as expected, you more or less dedicate the cam to FR with the way you mount it.
Anyway, if the tradeoff could start and finish with ANPR, it could be more than great. I do know that you guys like that feature very much but in my case, no camera is supposed to be pointed to the straight line of the street.
Moreover, the cams that are supposed to use the FR are pointing to the gates that are 90 degrees to the street. just by pointing them to the gates I give up the ability to see license plates.
If I could expect tradeoff, it's the IVS VS ANPR. From what I could understand, you need to choose between the two. Not sure if I understood correct though
I was looking for the combination of IVS+SMD+FR [if Human is crossing the fans, if Human is stranger and enters the gate etc.]
