Why would there be anything interesting about comparing a T54PRO-ZE versus ... another ... T54PRO-ZE?!?
Well ... it might provide some insights into unit variance ... albeit it's only two cameras. Plus when I had 'em mounted several feet apart (vertically), I thought I was some softness in the periphery ... so now we can do some serious pixel peeping! ;-)
FYI FWIW is that the first one came directly from China and arrived on 10/3/2025 with the second (logo in the bottom left) ordered on Amazon and arriving on 10/18/2025 - both ordered from @EMPIRETECANDY who (as typical) handled things well and I would recommend. Looking at the serial numbers (that are in Hex), the "newer" one is higher by "17D70" ... which is 97,649. But the difference in the MAC address is only "3F" which is 63 ... and the latest camera being LESS ... so who knows what that means?!? ;-)
Both running 0827 Firmware from Dahua with identical (fairly generic) settings.
One thing I noticed earlier that still exists here (as I suspect it would) it that the both camera's are set to zoom=550 and have very similar field of view (see GIF below comparing them) ... but the focus numbers are about 1645 versus 1745. I was kinda surprised to see that much difference ... albeit I don't think that's a big deal.
I'll have this up for another day or two ... so if anyone has any suggestions for "interesting" things to look at, let me know.
