Yes as Andy said, I’m working with Dahua on the FW improvements needed per my video feedback. Will post updates soon and where work may still be needed.

Just letting everyone know, I'm still testing this one (bullet cam first) and recently tried 2 new FW updates on the unit featured in this review. There is still work that's needed on the alignment so I've captured further data and fed this back to Dahua. I've also again made recommendations to allow for manual alignment of the lenses in the GUI. I'm expecting the next FW in November so will keep you posted

Looking forward to trying it out. I'll post my thoughts and clips up too.

Well, mine just arrived, the turrent version.

It feels like I've missed something somewhere, but at the moment, at night the resolution looks like the equivalent of 1080p... or slightly worse.

Both at 2688x1520

IPC-HDBW5442R-ASE-NI (my existing long term settings)

Then here, trying to align the settings between the two. Shutter 1/25, BLC, Natural, 2688x1520.

Then, here from the "Main stream" at 2688x1520, and then "Sub stream 2" at 1920x1080, from the same camera ... they look too similar ... o_O

Hope this is either firmware or my stupidity. Looking at the video feeds without noise reduction, the pixels and noise looks larger than my existing camera ... definitely more like 1080p pixels.

What is your codec and bitrate?

Use H264
smart codec off
CBR
bitrate 8192

for starters and then adjust bitrate up/down until the image improves or degrades.

Awesome video!

I do have a couple of requests for future videos: 1) can you zoom the 5442 to more closely match the 5449 focal length? I think that will help level the playing field and make it easier to compare. 2) In your nighttime comparison with the 5442, I appreciated the fact that you kept the 5442 in color mode and you definitely need to continue doing that in any future videos. However, would it be possible to include some comparisons with the 5442 set to IR mode too? I'd like to see how well the 5449 compares to the 5442 in IR mode as well as color mode.

Thanks for getting this together. I know it takes a lot of time to do this.

@Wildcat_1 Any update on a night comparison with the 5449 (Dual colour) and 5442 in IR mode. The IR quality of the dual cam seems less detailed than I was expecting, based on your previous videos of IR cameras in that location. I would love the IR quality of the 5442 with the additional color overlay, but if I am trading off IR quality then I am not sure the 5449 is better (for me).

Funny you bring that up, I’m actually planning on closing out with that video in the next day or two along with a comparison of turret cams vs bullet cam on Dual Lens and will include the 5442 overlay as I usually do but in IR this time. To set expectations you absolutely will see a difference when comparing traditional IR vs fusion tech due to the continual lean towards looking for color and overlay provided by the 1/2.8” etc. Stay tuned !

I picked up the 5449 Dual Color and was hoping to install this weekend... question though... if I install above my garage door I was thinking of putting it below the flood light in the picture. The flood light is on a sensor and stays on all night. Would this cause problems with the cam?1636145591266.png

Well, 2 things I would point out, 1) putting it under the floodlight (assuming directly underneath) is really too high, aim for 7-7.5’ max. 2) if the floodlight is truly sensor driven (I.e motion activated) then you do run the risk of causing ‘bloom’ to the cam as its potentially washed out briefly when the floodlight comes on and cam has to adjust. Therefore constant light so you can dial in the cam for the FOV would be more ideal so you don’t risk the bloom effect of the motion flood that could impact your ability to capture usable images.

No what I meant is the light is on a dusk to dawn sensor so when it comes on it stays on all night long....I saw a neighbors house across the street and he has a bullet cam located above his flood light but mine doesnt have that much room between the eave and the floodlight fixture so I figured I would install directly below it but didnt know if having the lights above the camera would cause issues
