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

    While the upload date may show 2026, I'm pretty sure the latest firmware is 12/17/2025 ... which should be "V3.146.0000000.5.T, Build Date: 2025-12-17" Speaking of which, any mention @EMPIRETECANDY of another update coming?

    2025 New Arrivals From EmpireTech

    LOL that @EMPIRETECANDY is going to have to start a new "2026" thread ... ;-)

    What's in the Pipeline for Dahua's 2026 Lineup?

    I've read elsewhere how the G6 Pro is a "good" camera in low-light ... but based on your experience, the current crop of Dahua's cams (S3) are much better in low light?

    T54PRO-ZE vs IPC-Color4M-TZ

    That's a GREAT side-by-side shoot-out ... I wish all comparisons were as good as this. The 5442 definitely appears better than the 54PRO ... not just in dynamic content (day and night) but even the daytime static content looks better to me. @wopi82 posted it in his review here where he makes...

    You can see the "shadow boost" in all of the images - look at the strip of grass in front of the house and the bushes in the back. As I said, have you tried Backlight HLC=ONE

    Here's a comparison of those two images that show the "fog" I'm talking about. Check out the golf cart, tires, grass, bushes in the back, etc. First animated GIF is your images "lined up" as discussed below - second is the originals you posted. As mentioned earlier, your cameras aren't lined up...

    B54PRO-Z4E first impression

    Have you tried the Backlight HLC=ONE "hack" on the T54PRO-ZE ... that first image with the golf cart especially looks like it has the "fog" overlaid on top of it ... so no true blacks, plus loss of sharpness. Super-simple to test in a static scene - take a snapshot via the web interface, ONLY...

    Roger all that @tmxv4128 and yea, I figured you were a "deranged photographer" (meant as a compliment) as I was. As you know, there is a mantra in our world to "expose to the right" ... since (with RAW), we can often recover/tame those highlights ... but hard to recover details in the blacks...

    B54PRO-Z4E first impression

    GREAT report @tmxv4128. I've highlighted items #6 and #10 because they seem possibly contradictory if I'm understanding it right. I also think there is more dynamic range (with true blacks and better highlight control) ... but when you say "flat response", do you mean the histogram doesn't...

    Assuming similar values (at least shutter speed), the 5442-S3 is clearly superior to the T54PRO-ZE in those pics!

    B54PRO-Z4E first impression

    I'm real interested to see what others show/think of the 1217FW in non-overview scenes ... comparing it to earlier firmware (same camera) and also against the 5442-S3 which is the reference.

    B54PRO-Z4E first impression

    In IR, if I want to do a 6msec shutter speed (iris 100), I'm already at gain of 60, which is pushing it ... and that's my last "dial" to adjust. Sure, I can make the gain even higher on the 5442-S3 to match the brightness of the T54PRO-ZE, but I'll pay the price in terms of increased noise. In...

    @bigredfish : Look at the shadows in the poster image of the Youtube video - there are at least two light source - one on the left side casting the faint shadow behind and to his right, and a stronger light on right side casting the darker shadow behind and to his left.

    B54PRO-Z4E first impression

    OK - I was just confirming that yea verily, that isn't happening with my cameras. Roger that - I've talked about the "Pig-Pen Dust Cloud" ... but I think that might be improved/reduced in the 1217 Firmware - wish I still had the 2nd 54PRO-ZE to directly compare. However, I can compare to a...

    T54PRO-ZE at 1/4000s shutter speed in Color mode ... all you see are the driveway/neighbor lights. Note that I have to set Backlight BLC=1 ... because if Backlight is OFF, there is a shadow boost applied that I've talked about ... but it just adds a smidgen of halo around those lights. Speaking...

    Your neighbor's consumer cams produce a great static image at night because they using a super-slow shutter speeds ... have them set the same as the Dahua and compare!

    Here's the same scene comparing the T54PRO-ZE (FW1217) versus the 5442-S3 in COLOR As discussed ad-nauseam above, there is a dark scene ... much more so since not in IR, so the IR illuminator doesn't help out. Our settings here are (OMFG!) 20 msec shutter, 100 iris, 100(!) gain, and 50/50...

    Good points @bigredfish in your post a few back ... because yes, capturing motion is the ultimate objective. But if camera #2 can capture a "better" still image (at "similar" settings) than camera #1, it probably is going to do better in video. And even if it's not "acceptable" (we always want...

    Yea, shine two flash lights at the same target and they will be additive ... Added: If you are comparing (just) sensor/lens/processing between the two camera's, then ideally you would want an external IR illuminator (located equidistant between 'em) to provide the same light. However, that...

    Regardless of the distance, I'm just suggesting if you are comparing, the FOV could be more similar to minimize any differences from that.

    Roger that and good luck with your testing @bigredfish BTW, the Field-of-View of the 5459 is wider than the 5442 - very obvious in the vertical as you did an excellent job lining up the top, but look at the bottom. Not as obvious in the horizontal, but still wider. This would contribute to...

    B54PRO-Z4E first impression

    I got that ... but if you are trying to do a straight-up comparison of the exposure between the two cameras (or different firmware), you have to force-set the same settings. And ideally I would UNDEREXPOSE the image slightly ... so there is no doubt (with THOSE settings) that the camera is...

    B54PRO-Z4E first impression

    FYI that you need to set a VALUE for shutter/gain/iris ... NOT a range ... since the camera can then play with those variables so the overall exposure is similar. I.e. I set gain to ZERO, Iris to full open, and then played with a specific shutter speed until the image is under-exposed. Then do...

    To echo what @tmxv4128 said about the 1217 firmware being brighter, here's the T54PRO-ZE compared against the 5442 with the exact same settings. Shutter speed is forced to 1/4000s, Gain is 0, Iris is full open, and NR is zero and toggled off - i.e. I tried to make a straight shootout of the...

    FYI FWIW that I had no issues applying the 1217FW to my T54PRO-ZE - differences from 11/27FW in BOLD below. It's daytime here ... at a very quick first look in daylight, images appear similar, although may have been some slightly improved tonality changes ... albeit hard to tell since the...

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

    @EMPIRETECANDY : any chance of getting some sort of explanation from Dahua on this? Seems like a significant change for just an HLC=1 adjustment.
