    T54PRO-ZE Field-of-View (and change in aperture/exposure) as focal length changes

    Yes @bigredfish it's totally normal ... I was just characterizing what the "curve" looked like using "real" data. Thanks for chiming in @wopi82 as your testing is superb.

    Review - EmpireTech IPC-T54PRO-AS 1/1.8" CMOS 4MP WizColor

    Thank you @wopi82 for the detailed and informative reply to various comments from folks. Yea, I remember your ISO stuff from the 4K-X review ... I thought maybe they made this easier ... since comparing against "reference" images is a lot of work, especially if you are looking at "adjusted"...

    That's pretty darn good! P.S. I noticed @guykuo you are from Sammamish, WA ... as someone originally from that area (with family still there), how's the GAR (Gogzilla Atmospheric River) treating 'ya? LOL the rain on audio is a hint. Hopefully you aren't too low/close to the flooding rivers.

    Providing a pointer here in case anyone didn't see it that @wopi82 posted some excellent stuff on the T54PRO-AS here.

    Review - EmpireTech IPC-T54PRO-AS 1/1.8" CMOS 4MP WizColor

    Yea, "core imaging performance" is the foundation ... I hope Dahua Engineers/Management read what you wrote. And yes, as you point out, unknown how much of this is due to global political situation that hasn't allowed advancement in the base sensor technology.

    Review - EmpireTech IPC-T54PRO-AS 1/1.8" CMOS 4MP WizColor

    First, GREAT to read your review @wopi82 ... as others have said, I welcome you chiming in more often. WRT the PRO looking WDR'ish/Plasticy: Did you try setting Backlight HLC=1 (yes, just ONE). This can make a surprising difference often times (you'll get "true" black back) - suggests to me...

    B54PRO-Z4E first impression

    The 54PRO seems (generally) "better" than the 5442-S3 for STATIC content ... with it having issues on DYNAMIC content ... so my "Pig-Pen Dust Cloud" is a catch-all expression that would encompass noise/ghosting.

    B54PRO-Z4E first impression

    Yes ... and great examples - I like how you did an excellent job showing it. I was just pointing out that it appears on the 4K ... and seems like a similar phenomena on the 54PRO, but much more pronounced. I would think(?) that the final codec/compression is similar (between the 5442-S3 and...

    B54PRO-Z4E first impression

    Nice lights! Would you agree that with 1/166s shutter speed, the "Pig-Pen Dust Cloud" persists longer than that? Just pointing out it "exists" with the Color4K ... but I'm guessing that if you put a 54PRO with similar settings, the "Pig-Pen Dust Cloud" would be "bigger" and "longer lasting" ...

    B54PRO-Z4E first impression

    Curious what the 3NR setting is on the first color camera where the dude drives his pickup across the grass. It's a good capture ... but you can see the "Pig-Pen Dust Cloud" behind it as it goes from right to left ... but it's fairly short/quick compared to the extreme examples I've posted in...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    I don't want to sound like a Dahua fan-boy, but I'm pretty encouraged by what I see in the 54PRO (versus the 5442-S3) and the improvements in the firmware ... both visible and IR. Yes, we don't know if gain=70 on the 54PRO is the same as gain=70 on the 5442 (and if there is a "extra" AI boost)...

    Yea, your examples have been great ... for instance, LOL that you too are "Pigpen from Peanuts with a dust cloud" behind 'ya! ;-) Plus your stuff and others are much more representative of typical use cases versus my "scene" shots. And LOL I obsess over the Pixel-Peeping! ;-) I wasn't...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    What do you think of the COLOR video? Below is a GIF of them with the two JPEG's pulled from the video. The 54PRO blows away the 5442 - especially in static content. Not just brightness/color, but look at the sharpness of the shirt/bag in the driveway, the trees to the right and across the...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    I did look briefly at the on-board IR ... but I'm very confident that it's not as powerful as the 10-Watt Tendelux DI10 ... and for THIS SCENE, I need all the light I can get ... plus widely dispersed. Obviously for close-in-work, you want the onboard light to "work with" the camera ... but I'm...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    BTW, back to the Tendelux IR Illuminators, I agree with others that the light distribution seems pretty even. In fairness, my situation is "best case" ... as it is mounted at the top of the house ... so it's a "long" distance to the target which reduces "distance squared" issues ... and looks...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    Oh what the heck, here's the videos. Again, this is an unfair test as it is wayyyy too dark. Please read the explanation/disclaimers about this REALLY DARK scene in my earlier post ... where I closed with "I think they reinforce what I've said that the static content is better with the...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    Since we are currently talking about IR illuminators in this thread, I'm kinda reluctant to post a T54PRO-ZE versus 5442-S3 comparison (maybe more appropriate in the other one) ... but here are the images above combined into an animated GIF without and with IR light. Please read the...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    So @wittaj asked the very good question of (basically) what is the existing light at a "reasonable" shutter speed of 1/120s ... since the first thing photographers do is look at what we have to work with ... and then decide how much "light we want to bring to the party" This is a DARK SCENE ...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    In answer to the question of where I mounted the Tendelux DI10 IR light, a picture is worth a thousand words. Having said that, if you look carefully, you'll see a "triangle" pattern of holes drilled a little further back from the edge of the roofline. There is where I originally put it ... but...

    WOW ... I stand corrected ... that's a pretty sharp license plate!

    B54PRO-Z4E first impression

    Is that a @tmxv4128 image enhancement on the license plate?!? As someone who fiddled with LPR cameras several years ago for our HOA, the plates really do "light up" with an IR illuminator ... and if there is LPR processing on the camera, it may further enhance it (plus put the the...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    Here's a pic just after I installed the DI10 ... the middle of the driveway is about 50 feet away from the camera ... so while this is lit up decently (albeit slow shutter speed with lots of gain/NR - still fiddling with the 5442-S3), more light is always better. I don't "really" need to light...

    Review- EmpireTech IPC-T54IR-ZE-S3 4mp Varifocal Turret

    I believe the field-of-view is basically the same for both - right? I've debated getting the bigger DI20 ... I don't expect it to turn night into day (in the IR spectrum) ... but in your experience, is it a LOT more that ends up making a significant difference?

    Dahua WizColor 5x59-PRO and SmartLight 5x59-IL new series

    Average annual snowfall here is almost 100" ... but we get a lot of sun, so the non-shady parts melt down. Didn't mean to imply it's just about "pretty pictures" ... since yea, gotta be able to capture movement ... and you/others have done some great testing in that area. As you well know, the...

    Dahua WizColor 5x59-PRO and SmartLight 5x59-IL new series

    @EMPIRETECANDY Agreed that the 54PRO is warmer (both are set to Auto White-Balance) and I like that look. Ditto that I too see more details on the trees and foliage in throughout the picture - might be some AI processing going on there(?) as these can be very difficult for sharpening...

    Roger all that @bigredfish ... and sorry if I traumatized you with the snowy picture ... better not scroll down! ;-) As implied, I don't consider this a good test of cameras ... but I couldn't wish attempting some humor saying WTF with all the (white) noise in the video ... I just mounted...

    Dahua WizColor 5x59-PRO and SmartLight 5x59-IL new series

    So here's a "snowy" comparison between the T54PRO-ZE (running 11/27FW) and 5442-S3. They are vertically separated by just less than a foot ... and I've tried to frame them similarly. Both have same parameters of 10 msec shutter, 100 iris, 0 gain, 0 2D/3D NR (and toggled OFF). As you can see in...

    Speaking of the 5442 ... and sorry if I missed someone pointing it out ... but @EMPIRETECANDY has new firmware for the "IPC-T54IR-ZE-S3" on his website that was uploaded in mid-November. I'm currently running "V3.142.15OG003.0.R, Build Date: 2024-12-21" ... with the new "IPC" file saying...
