I did tweak the settings for both the day and night profiles but didn't try tweaking the settings after I switched on WDR. I doubt if I'll need WDR here. These are the final settings that I used for the day and night profiles.I also find (Hikvision, Dahua and other brands) that they all need their settings tweaked to get the best at night.
Is it possible to read firmware from one camera and flash it to another?Few days ago I have received these cameras. I have it with two diferent lenses 2.8mm and 3.6mm. Cameras with 2.8mm lens manufactured two months later and have newer firmware than cameras with 3.6mm lens (firmware 2.400.0000.10.R 2015-06-18 vs 2.400.0000.7.R 2015-04-22). And this new firmware has higher maximum resolution of 2688*1520 (vs 2560*1440 in older firmware). So its true 4Mp not 3.7Mp
If you want to get this higher resolution ask you sellers to send you newer firmware.
I moved the camera to a new temporary location. Here are a couple of snapshots, first one with WDR off and second with WDR on and set to the default 50. Finally got some sunshine today. Will post another capture later tonight. Camera has 2.8mm lens.
WDR Off
WDR On (50)
It was sunny when I took both snapshots, but it's possible that there might have been a cloud moving by on the second shot that partially blocked the sun. I'll try again on a clear day with no clouds. Today, it's all clouds and rain.Since there's some puffy cumulus clouds in your shot, do you happen to know if by chance the sun was behind one of the clouds during the WDR shot?
This is an unfair comparison. The HIK shot looks more blured than the dahua because the resolution of the HIK is only 2Mpixels rather than the 4Mpixels of the dahua. The dahua is certainly crispier due to the resolution.This is more of a FOV comparison than anything else. Here is a single frame captured by my 2.8mm DS-2CD2332-I @ 1080p along with a single frame from my 3.6mm IPC-HDW4421C @ 2560 x 1440.
The Dahua turret is positioned about 8" above the Hik.
Thanks! That would be very helpful just to make absolutely sure we're comparing apples to oranges. I know on my Hikvisions (3mp non-WDR) that the image can look perfect while the sun is shining but as soon as a cloud rolls over partially blocking the sun, my yard turns so dark that you almost can't even recognize the plants.It was sunny when I took both snapshots, but it's possible that there might have been a cloud moving by on the second shot that partially blocked the sun.

Next time I'll try tweaking the brightness, contrast, sharpness, etc. with WDR turned on, although I'm pretty sure I won't be using it here.
Since I stated that it was a comparison of the FOV between two of my cameras at specific settings, I don't know how you can say it was unfair. Do the two pictures not demonstrate the FOV seen by each camera?This is an unfair comparison. The HIK shot looks more blured than the dahua because the resolution of the HIK is only 2Mpixels rather than the 4Mpixels of the dahua. The dahua is certainly crispier due to the resolution.
Since we all know that the FOV in camera changes between different resoutions, at least configure the two cameras at equal resolutions.
Here are two more captures. The sun was out and equally bright in both snapshots. All controls with and without WDR are set to the default, which is mid range (50). I haven't tried tweaking the controls while WDR is on yet.Thanks! That would be very helpful just to make absolutely sure we're comparing apples to oranges.

Thanks for the comparison wxman. I have no experience with WDR and didn't know what the advantage was to have it enabled. As you mentioned, it seems like the WDR with the Dahua didn't do much more than decrease the contrast. Must be digital and not be true WDR right?Hmm, very strange how this WDR works. Sure seems like it just reduces the contrast of the image. I downloaded the images and put in a photo editor and can digitally enhance both images to look basically identical. I can't really distinguish much (if any) "range improvement" in the WDR. I must say that I'm disappointed and really wonder if this is "true" 120db WDR like it's supposed to be or just some type of digital WDR.
