WRT #4, instead of a "push" from the camera to the web server/cloud, you might consider a "pull"- ffmpeg is your Swiss Army knife here. It sounds like you are well aware of security issues ... so yea, make sure you have 'em locked down well. BTW, I have a some IPC-T54IR-ZE-S3's running version...

LOL on dude wearing full Camo-Gear plus Camo-Hat ... is he hoping that will help him blend in with the surroundings so the Owl isn't "spooked" by him ... versus the dozens of other people milling around! ;-) P.S. More Canon cameras? "Big Whites" are probably 70-200, 100-400, and guessing...

Once again, great info @steve1225 - I appreciate that you even mentioned that the image ratio needs to be the same. From my experience (reviews and hands-on) camera lens focal lengths aren't always quite what they claim to be ... but they are usually pretty close. So I appreciate the education...

Thanks a bunch @steve1225 for the great info! Got it that Z4E was fixed aperture through the entire zoom range - sorry I didn't fully realize that. Yes, wide-mildtele is more difficult lens design than mildtele-strongtele. Thanks for the FOV data ... and yes, I should have looked this up. So...

Yes ... i.e. for the same field-of-view, when the Z4E wide open (8mm), what is the "zoom level" on the Z4 which goes from 2.7-12mm. And the REAL question I'm trying to answer is what is the difference in aperture at those settings - i.e. how much does the ZE close-down? Since for the same...

Ooops ... 16->32mm typo fixed in post above - thanks. Good into @wittaj - you would certainly have an excellent "feel" for the difference. To be clear, those are both S3's - right? And when the Z4E is wide-open, what "zoom level" does that correspond to with the Z4? Here's an example of a...

Circling back on the "how does the aperture vary with zoom" question ... and thanks @steve1225 for your info. I'm debating replacing a ZE (2.7-12mm) with a Z4E (8-32mm). The "Zoom Level" on the Z4's go from 0-2275 (wide-tele)... and one of mine is at 400 ... which I suspect is wayyyy wider than...

Great info - is the aperture variation with zoom setting documented anywhere?

WOW - impressive tear-down ... great pics!

Ditto what @joqhith (and @wittaj) said about "cable termination/corrosion issue" ... especially if you don't have the connections WELL protected from the elements. I'm guessing you have a female-female connection that joins the Ethernet cables somewhere up there (totally "get it" that it might...

What I found most impressive how well it did with license plates that are lighted ... AND those that are not. And this is visible light - i.e. not dialing in an IR light for an IR Camera. Well done @Parley!!!

Boy ... that sounds strange ... sorry I don't have anything to add beyond what I wrote in post #65 - was uneventful for both of my IPC-T54IR-ZE-S3's. Hopefully it will "take" this time and you'll end up with the same versions that I noted. BTW, I say "cancel" when asked to open...

To be clear, shoot at EXACT same settings ... so we can see the difference between sensor, lens, and image processing. Sure, gain (and noise reduction) might be different between the two camera's, but exposure is exposure. Thanks in advance! P.S. You probably want to snarf PNG's from the web...

That's pretty impressive by the 4K-X at 1/120s exposure and only 35% gain ... I'm looking at the dark areas across the street. If easy for 'ya to do, be interesting to see a comparison shot (at night) with the 5442's in color with similar settings.

If you only have a single run and want to run multiple camera's, you might consider a PoE extender switch. I got this one a few weeks ago and it's been running with no problem in production - it ran three camera's with no problem - just make sure you size the upstream PoE injector appropriately...
