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

BTW, if you think that setting the the "3D & 2D NR Levels" to ZERO means no NR, that is still NOT the case ... as even when they are both 0, toggling the "3DNR" button does a fair amount in a low light scene when you are "pushing" the camera.

If you set NR to zero it seems likely given the way AI-ISP is probably working that it's going to apply NR anyway as it can't perform it's improvements without, either that, or it's going to also set AI-NR to zero in which case you're going to get a completely unprocessed picture which has the potential to be terrible if the AI still applies the same levels of gain (assuming that's what it does).

The big questions I'd be asking is does setting it to Zero turn off or reduce the overall NR processing, or does it actually force it to apply more AI NR to make up for the fact the picture is probably more noisy in the 1st place? It's possible you could get more AI NR by setting manual NR to zero.

The question is does this happen and if it does, is the quality better under AI NR or a combination of manual & AI NR together?

Is there also a sweet spot between manual and AI NR combined?

Does reducing the manual NR setting affect only the AI-NR processing or does it also affect the levels of gain that might be applied?

Putting together a list of bugs/things that need resolving on the 54Pro ZE model using latest 1127 firmware, for my own reference and maybe others can add to, or expand on:

● Reduced quality output in B&W at night.
● Poor quality output in colour at night (smearing, artifacts, ghosting on lighter colours and vehicle lights).
● Low light sensitivity in both colour and B&W seems poor generally, compared to S3 series at least.
● Inconsistent frame quality during daylight hours - over 20-40 frames, 10-20% are sharp, the rest very average.
● Sudden exposure changes mostly in darker conditions both B&W and colour (normally when a vehicle or larger object passes through the scene).
● Using firmware 1127 sub stream is darker on resolution below 1080.
● Issue with auto white light illumination (staying on during the day?).
● NR still applied even when toggled off.

Pretty sure others might have flagged IVS issues, I am not up to speed on these as mostly been focusing on image quality output for my own testing so far. Please add anything else, might be useful for @EMPIRETECANDY to see it all in one place. :thumb:

****Something you may not know and is demonstrated here, there is a difference in image settings between having IVS OFF and ON

Make sure you are making your settings with IVS enabled and know that if you disable IVS, your exposure and other settings will be changed by the camera without your input

This thread explains it and humbled me as I wasn't aware and learned something new. Thanks to @Zoltán Szabó @laurscr and @wittaj for bringing this to my attention.
I'm betting there are others who don't know this.
I don't find it useful, frankly I think its dumb and can easily lead to unnecessary images issues
It does this in both B&W/IR and Color modes. Even more dramatic in B&W

Thread 'HDW5442TM-AS – Washed-out image with IVS on latest official FW – Is downgrade to SmartIR possible?'

Hi Everyone,


I have several IPC-HDW5442TM-AS cameras. All of them have been running the latest Smart IR firmware by EmpireTechAndy:


V2.840.15OG00D.0.R.220818


On one of them – an older HDW5442TM-AS model – I decided to switch to the newest official Dahua firmware
(hoping the updated IVS algorithm would reduce false alarms):


General_IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.840.0000000.30.R.250227


The upgrade completed successfully and I fully reconfigured the camera manually (no config import).
The Algorithm Version changed from 1.0.7 →...


Check out this video. The first 15 seconds are with my settings and IVS enabled. Then I turn IVS OFF. Can you see what it does to the image?
You will want this to be full screen to really see the noise introduced.

And the settings the camera chose when I turned IVS OFF

I get the explain.

IVS saves a separate set of web configurations when it's on and off. This mainly involves the function of multiple sets of intelligent image parameter configurations. Each intelligent scheme will have an independent set of image configuration parameters. When switching intelligent schemes, the image configuration parameters will also switch to the previously debugged parameters, which helps to improve the intelligent effect.

I'm just making sure I have IVS set and enabled before I bother making any settings.

But yes if you think you might turn off IVS at some point, you n need to make two different sets of settings. It affects Day AND Night/IR

The 54PRO wasn't very good at animal detection this morning. Deer spent a full 2 minutes in the camera's FOV before detection just as it was exiting. Large scale models are enabled.


Capture.JPG No detection

Capture1.JPG No detection. Loitered here for a full minute.


Capture3.JPG Still not detected, 12 feet from the camera.

Capture4.JPG Finally got it just before exiting the camera's FOV.

I don't think that's the issue here. The issue for me is when the camera first detected the deer as an animal, as shown by when it first put a green box around it. It moved all the way across the FOV from left to right, first detected just before leaving the FOV on the right. This picture is the very first green box.

I think you have a 3D effect going on.

Those boxes seem to be drawn with 2d thinking.

Create a single intrusion box that runs along the bottom of the fence line all the way around, as if you took a square built frame the size of the area and layed it almost flat on the yard

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 the videos at the bottom, both are having issues with "white noise" - can you get this fixed @EMPIRETECANDY ?!? ;-)

More seriously, snow is REALLY tough for any imaging system ... since the RGB values are very similar ... so any compression algorithms will squash any details as they are very slight.
Also, the 5442-S3 has Backlight OFF ... but the T54PRO-ZE has HLC=1 (only one!) ... which seems to increase the dynamic range ... although I think the behavior is a bit different and not as pronounced as earlier firmware, but I no longer have a 2nd T54PRO-ZE to compare directly to.

Also note that shutter speed is 1/100second ... which is fairly slow for daytime ... but figured that would highlight any blurring that is due to differences in camera processing ... although obviously this is NOT a low-light test and Gain/NR was (hopefully!) completely turned off. I didn't look that closely, but both seem decent - welcome others reviewing/commenting.

Interesting, I like the 54Pro better in this case!

On my deer non-identification, I'm trying the suggestions that were offered: Created an intrusion box with appears+cross and changed the tripwires to zigzag, both directions. Also cranked up the individual rule and global sensitivity from 5 to 8, and did the global calibration. I still don't expect any of these will do a thing until the camera puts a green box around the animal.

These changes also broke something. The NVR can't live view the camera any more . BI and smartPSS still can, and the NVR still records ok, with the recordings viewable on the NVR and smartPSS. Rebooting the camera didn't help.

Good job on synching the time and view!

May just be my bad eyes but with the two individual snapshots, first thing that drew my eye was the city name on the plow door and actually reading the letters..... the 542 was easier for me to recognize the letters even th9ugh not as "bright"

There are known inherent differences in the two cameras. Dialing each in to their best image quality better tells me what CAN be with the right settings vs using non-normal identical settings.. Like the tweak you made to the 54PRO. Personal preference, to each his own.

That said, it agrees generally with what I've shown with there not being as much difference in daytime as at night between these two cameras.
Not surprising, Light makes everything better! We could probably take other Dahua series cameras with 1/1.8 sensors and see similar results.
Though the 54PRO is still a smidge softer during daylight in my still captures and video, its close enough that I would be ok with either as I've said..

At night, the 5442 S3 kicks its ass

The other thing folks, especially new users, need to know is that these are setup as effectively "Overview" cameras. Its much easier to see a "good " image when targets are further away than up close. There is less detail at distance. Much harder to get good blur/noise free images closer in with real facial ID. This is why most camera marketing videos show video of pretty skylines.

As a daytime overview camera its damn near as good as a 5442 S3


Biggest thing for me on your test is that I remembered why I moved South in 1977

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 an external IR illuminator ... so I may do some IR testing ... although the rest of you are much more knowledgeable about stuff like that.

BTW, it goes without saying that at night, with the IR light on and the camera in IR, that "white noise" is REALLY noticeable! ;-)

That white noise was fun from age 2-12
We used to make tunnels through the yard when accumulation got to 36” and I had some mean snowball battles with ice forts with the bully across the street. :rofl:

Then at about 12 I learned I could make money pushing that white stuff off of sidewalks and driveways.

Snow sure does play games with cameras. Look forward to your IR testing
