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

For completeness, here's the Histograms for those two sets of images above.

There's a noticeable right-shift in the (top) 1509 pics ... whereas the (lower) 1656 is much closer.

I'm not sure this really tells 'ya much (except that the metering was brighter in the earlier 1509 which had more sunlight) ... since the scene is different (bummer I don't have 'em side-by-side) ... so the "Mark I Eyeball" is probably a better judge.

Yes, ZE is vari-focal ... both set at zoom=550 (on a scale of 0 to ~2,500) ... but as noted before, the focus numbers are not that close ... about 1640 & 1740 ... so make a slight difference in FOV. And yes, it's an overview camera as shown.

Here's a comparison a little more than an hour before sunset. Looking at the histogram in Photoshop, the metering is much closer. I set the White Balance to Auto because it was also closer ... albeit still some difference and maybe some saturation boost in the 1022 Firmware ... which I think is a more pleasing picture. Everything set identical - 5 msec shutter, 100 Iris, ZERO Gain/NR.

can u post these 2 pictures separate as well as the animated gif you have.

Here 'ya go - PNG's straight from the web interface - had to resave as JPEG's because the 2nd PNG would upload, but not "take" ... for reasons unknown, that seems to happen sometimes - they are almost 10MBytes!

From Alekk's pic compare the new one now not such blue and get sharper on grass and the street trees not too white, pic is sharper, watch on the grass.

Now that you mention it @EMPIRETECANDY, there is a blue shift in the histogram - the 1022FW shifts to the left compared to 0827FW.

Again, the scene is different (bummer I don't have 'em side-by-side anymore) ... so it's not directly comparable.

Ah yes...the grass is greener on the other side

@EMPIRETECANDY : Minor suggested documentation update and/or change in setting behavior.

So during my daytime tests, I have set the NR (Noise Reduction) to 0 ... AND ... toggled 3D NR OFF ... which seemed redundant since the level is to set to zero anyway. Turns out that doesn't appear to be the case!

This is easily seen in a semi-static scene with both the 0827 and 1022 firmware. Set 2D/3D NR to ZERO and toggle it off. Then use some exposure settings (with lots of gain) that generates a fair amount of noise in the image.

Then toggle "3D NR" to ON ... but leave it as zero - the image cleans up quite a bit!

And THEN you can move the slider from zero to 100 there is more "improvement" ... obviously the tradeoff is that you are blurring any motion.


After saying WTF, I went to check the documentation ... the latest I could find was - Web 5.0 Operations Manual 1.2.5 - revision history says released August/2025.

On page 20, it talks about the various exposure settings. While it has separate "3D NR" and "levels" explanation boxes, to me it's not clear that enabling 3D NR (but setting levels to ZERO) actually "does something" .. which I found surprising.

BTW, that is the only place that "3D NR" is talked about ... and "2D NR" is not mentioned anywhere in the document.

I think it would be worthwhile to describe the difference - I assume 2D works on a per-image basis (classic NR such as Photoshop does) whereas 3D NR operates with multiple frames ... which it does say.

And it seems like the "3D NR" Button is redundant ... if you have set it to ZERO, it should simply skip that section of code ... which I think is the desired behavior ... rather than whatever it's doing now.
