DAHUA IPC-HFW2449TL-S-PRO Demo
- Thread starter eryigit
- Start date
Polish demo, where they compare WizColor 2449-PRO with 5449 Full Color and some 3549 TIOC in worst possible scenario: FULL DARK environment (NO LIGHT at all).
there is no 5442-S3 in comparison, but it will generate even much darker image that 5449 Full Color in this test (F1.6 vs F1.0 aperture - so 2x less light on sensor in 5442-S3)..
At the end they show also TIOC-PRO on some very alpha WizColor firmware (not available publicly)..
Please be aware that this is TOTAL DARK environment (forest), where our beloved 5442-S3 will show almost nothing in Color mode...
The new AI-ISP tech can create full color static picture for pleases where 5442-S3 will generate very dark almost no usable image.
WizColor / AI-ISP are using high dynamic gamma / color manipulation (very advanced HDR tech from mobiles) and high 3D noise reduction.
I see this on 3449 TIOC-PRO cams (on factory pre WizColor firmware), which at the same places as 5442-S3 generate much brighter and much more color-full static image that 5442-S3 (using the same shutter settings - so this is not long exposure)..
The main issue stay with movement, which in almost no light situations are very ghosted (very high use of 3D-NR) and noisy..
But for that those cameras have hybrid light - where white light can be activated by human/car motion detection in no light situation.

Meaningless.
I can take a lot of current cameras and make them look bright and colorful at night
a- with long range shots
b- brightly lit distant lights
c- no closeup faces
If overview in color is what you need, its fine, so are dozens of other cameras in the scenes portrayed in that video
The purpose here was to explain that the camera we are talking about has a wider aperture than other cameras. Of course, other models of cameras can capture images similar to those of the camera we tested for night vision.
The approximate distance the camera sees is 220M

So help me make sure I'm understanding.
Is the 2449 not using white lights at all?
None of the 3 are using their white lights?
yep, this polish test was done with illumination turn off on all cams..

Wow. I'd like to test one to replace my 4K-X
@EMPIRETECANDY can you get me one of these? 3.6mm OR 6mm

It would have been great had they tested all 3 with the LEDs on, that's how they'll really be used.
Looking closer at the 2449TL on a bigger screen on the Polish vid, it's not useful video with zero light, as expected without the LEDs, no camera is in color
On the Turkey vid it shows it does pick up light really well, but at distance with bright ambient light.... Having video of it closer in at usable distances (3-25M) with ambient light or the LEDs on would be helpful
I agree at distance where detail is less important, it is a light monster, with the caveats that @steve1225 mentioned.

What you mean this is a problem
Dude was barely moving. It would be useless in a home environment set up like this.
i booked a turret 2 weeks ago, said can be ready at Nov.20th.

I should have saved a cap but I saw a shot where he had 4 hands, two up two down by his side, and a pinkish blob for a face. Gold

I’ll buy it off you if nobody else does. But with very little light here, except one spot facing the street with a weak ass 1950 street light, I’m afraid it will look a lot like the Polish clip.
It would be great to test it against the 4K-X
Find another video on youtube in Czech. Google translate of the summary.
"Dahua WizColor – the latest technology for obtaining a color image even in minimal lighting. It combines an extremely bright lens (F1.0), a powerful AI-ISP image processor using artificial intelligence algorithms and a large image sensor. Thanks to this, the resulting night image has a significantly better rendering of the colors of the captured objects, more details are available and blurring of moving objects is minimized. Due to the better use of weak light sources (e.g. moonlight, diffused city light reflected in the sky), monitoring distances are not limited by glare and a full-color image is available for the entire scene.
The IP camera in our video is also equipped with WizColor technology - Dahua IPC-HFW2449TL-S-LED-0280B-PRO from the WizSense series."

@bigredfish please be aware that 2449-PRO is a very low-end line..
Plastic enclosure, weak SOC / processor (it can do only 20FPS for full resolution, for 30FPS You must crop image), some very basic AI (firmware is only 70MB so AI models are small)..
3449-PRO (Color4M in Andy shop) can be better.
Metal enclosure, much more powerful SOC, some crazy features not available on other models (like second stream in 720p or 1080p or all TIOC features
, speaker, nice set of LED's (IR, white, blue/red), 220MB firmware size - so AI models looks more like 5442..I want to do review / video comparison of 5442-S3, 5449-ZE-S2 (I have second generation available in Europe), old Color4K-T and 3449-PRO (TIOC-PRO) next to each other, without and with motion activated white LEDs on TIOC-PRO.
But I wait for final production ready WizColor firmware for TIOC-PRO.
Dahua promised on page about WizColor technology that firmware for October, but they as always didn't released it yet..
I have some never version not released to public but without Release Notes so I don't known is this with WizColor/AI-ISP tech or not..
ps. does 4k-X and 4k-T differ in video quality (as I understand different SOC & firmware)? I have only 4k-T..

That video doesn't make it any better.
He has a phone shining in his face and still can't get good recognition
As @bigredfish said, we can make any camera look great with a static image with a slow enough shutter.
Sure this looks impressive with basically no light, but when you have played with these enough, you can tell the lack of "sharpness" in this photo and just off colors shows it is being pushed to the max. I am sure motion would be comparable to Reolink blur.

I have both of the 4K models, I don’t see much difference in picture quality, except there is a difference in focus range. Both older models in 3.6mm
The biggest difference I see is in the FW. The newer bullet (I have 2) with latest fw is much noisier than the original (‘22 fw)
I’ll test them side by side hopefully this weekend
