Does anybody even use camera-side zoom? It would seem to have several disadvantages, not least of which would be that you end up recording only the zoomed FOV...
Is camera-side digital zoom usually applied to all streams, individual streams or individual connections? Does everyone use the same basic scaling algorithms or are there significant differences?
Is the correct formula actually Total Zoom = max optical zoom X max camera side zoom X max VMS zoom? .....Ok I'm kidding about that one! ;)
