On your review thread it states
*Note that in most of my tests I allow the motion activated flood lights to come on a this is how I run them normally. For this test, Ive turned the motion floods off because, well, this camera simply doesn't need them!
Out of the box on default AUTO settings the light pickup is pretty intense.
*Note: there is no floodlight on.

Hmmm I'll have to go back to the review photos. It could have been set to 1/60. I can assure you the image in the comparison is how I run them currently. I think with the motion flood the 1/60 setting was too washed out..

Here's the post with the comparison of the 5442 ASE and the 5442 NI from that review.
Note in the compare photos the 4th color set down, at 1/120
When the floods kick in it was too bright at anything slower than 1/120. I'm sure ive tweeked it since that test a year ago, but you'll see very similar to what I show last night at 1/120

Well Andy, when the varifocal camera comes out next year I will be spending some money with you. I need to save my money for the rest of this year so that I can afford my 2022 camera purchases. I can see at least 6 cameras.
My neighbors will be receiving some upgrades.

In those pictures that you referenced the detail down the street is better with the new Dahua 4K camera. I notice the same thing with my 4K Hikvision that is in the front of the house.
In playing with mine more, I think if someone has any available light, like @EMPIRETECANDY suggests, it might be better to run this camera with the LEDs off.
But in a complete pitch dark area, like midnight with heavy cloud cover so no stars, aimed at dark grass with out "reflective" concrete or buildings around it to bounce off stray ambient light, you will be surprised how well and bright this camera performs with just the LED lights in a completely dark location.
Put it on the front of the house where there may be streetlights, neighbors porch lights on, light bouncing off the street and driveways and homes, and this camera absorbs every bit of that light and makes use of it - much better than any camera I have seen.
Normally in my testing, once I start getting faster than 1/60 shutter, with each incremental jump in shutter speed, you see the image get darker. I didn't see that with this camera and initially I thought it was broke, so I jumped to 1/4,000 shutter just to confirm the shutter was working! It is amazing how fast of a shutter you can run with this camera.

Again these are VERY preliminary and I havent begun to tweek settings, but all at 1/120
Coach Lights ON, LED's OFF

@bigredfish i know you too will have no issues with dialing in but as always if you need any assistance or have any questions, just reach out.

Thanks @Wildcat_1
I’m gonna play with it a bit this week with the wife unit’s help as I’m remote one county away with mom. I need to go back through your testing and try out various setting combinations.
With these initial snaps one can clearly see the difference on the (gray not black) Jeep color, the blue Explorer and the brightness down the street at the same exposure and gain.
Much like the difference between the 5231 series with the 1/2.8 sensor and the 5442 series with the 1/1.8. It’s a another step up
At first blush, this new 1/1.2 sensor can be run about double the exposure and maybe more than that of the 5442 and get the same scene brightness, and at similar exposures it simply produces a brighter crisper image.

Yes as I showed in my test videos you can quite easily push the cam to new highs such as 1/500.
What I would also say is that with the 1/1.2” sensor this is one of the first cams that truly represents the scene accurately. I.e what you see with your eye can be represented (with the right config tweaks and adjustments) closely through the camera at night. That in itself marks a fundamental shift in the power of these cams and the exciting move to usable color images at night and in 4K that will only improve over the next 1+ year !
Still a lot to do in this market segment and improvements can be made as I’ve suggested under the hood to Dahua BUT an incredible start with a powerful and capable camera.
Lastly, this cam also provides enough headroom to adjust for noise, AGC etc as I’ve shown and suggested which is great as you are not boxed in.
As @Parley and i mentioned, the future which holds varifocals and larger sensors across the board means that there are some potentially very powerful and capable cams ahead and this cam allows you to put your toe in the water now

Can I ask a silly question or two? How much would the illumination lighting interfere with a 5442 using IR at night if they both look over a 2 car driveway from opposite corners?
I could use BI to havethe cam using IR detect motion at a distance, and activate the lights thencorrect?
Also when will the 2.8mm be available?

40 m (131.2 ft) (IR LED) For IPC-T5442T-ZE

The lighting from this would not interfere with the IR, but would probably end up improving the 5442 image as it would have more ambient light to work with.
These are not active deterrence lights on the camera nor are they motion activated lights - they are either on or off. If you could figure out the API command to turn them on or off, then you could write something in BI to accomplish that, but that is not the intended use of the LED for these cameras.

I don't think any sort of light would blinding to most intruders ,daytime or night don't matter to them all they are bothered about is where their next fix is coming from.
These things are not very bright at all, which is why up until this camera I said they were more gimmicky than practical. Once you dialed in a shutter to eliminate motion blur, the image got a lot darker as I showed in my video of my other full color camera. But not with this camera.
The LEDs on these would be equivalent to holding a cellphone flashlight up on your house. Bright if you look directly at it, but nowhere near floodlight capable.
It looks about like accent lighting on the house.
