I am dead serious about maybe two in those windows. I had never thought about putting a 4K-T up there until your post. You know I have light there. See the still from tonight for the SD12203T-GN.
So now I have the Dahua 4K-T 2.8mm on top and the competing Hikvision DS-2CD2387G2-LSU/SL 2.8mm right underneath it mounted about 7 1/2' high out front. This is definitely producing a lot of looks for people walking by, especially with a gigantic ladder out front with various object placed on different rungs.
@samplenhold Totally agree with Rule #1 now!
There is all sorts of quirks with and variations between these two cameras. I've spent the last couple of hours fighting with the image adjustment controls to get as close to a similar image as possible. I've been testing at night here with street lights, I manually set the shutter to 1/30 on both cameras. For both cameras, the WDR washes out colors. For both cameras, HLC produces the best image for me with both bright areas and dark areas, but I had to turn down the exposure compensation on the Dahua. Without HLC, the text on the box would be super overexposed, or after adjusting image settings the background very underexposed.. Overall I was able to produce a noticeably better night image on the Hikvision.
I also compared the microphone as I was having trouble with all the digital noise in the Dahua 4K-T. The Hikvision actually has some very noticeable background static, but nothing like the noise I was hearing from the Dahua. The microphone is definitely better in the Hikvision, and the Hikvision also adds a built in speaker. They're both not what I would call high quality audio though by any means.
Regarding the focus, I put a box with various sizes and colors of text on it out about 7' high on a ladder. Although the Hikvision DS-2CD2387G2-LSU/SL specs show a 4m to infinity depth of field, the Hikvision's close focus is quite noticeably better than the Dahua 4K-T's.
Anyhow, I think the right thing to do here would be to start a new thread for a comparison of the Dahua Color 4K-T and Hikvision DS-2CD2387G2. To be continued...
I have some compare here for hikvision color4k and our 4K-T. I have confident ours 4KT/4K-X can do bit better than those colorvu camera. Sure the colorvu cameras also are very good.Today made some compare for the IPC-Color4K-T with Hikvision 4K DS-2CD2087G2-LU. Has some compare here, both cams all in default and 1/1.2cmos
1. hikvision is aggressive colorful, the shelf blue are not the real color(esp when all light is on), even the wall become a silver. And the door is more a brown white color , it shows a little green, from our compare, 4KT pics can be more to the real color. But some guys may love the vivid pics If they just watch from the pics.
2. Low light wihtout any illumninator, the Color4K-T is bit better than hikvision one.
3. Build in LED light on, From our team's watching , dahua do better too.

Door becomes a little green. Shelf blue become very deep blue.

REAL light situation, with all lights off by iphone12, So you will see both cams are good for full color even no external light.

hi @Wildcat_1For reference, my testing are through managed POE switches
Now make sure to modify that 1 star review on AliI just got my second camera from Andy, and I want to say thank you for the quick delivery. I chose the 4k-t 2.8mm in black, and I must say it looks fantastic. I also managed to get my hands on two NC800 cameras that were accidentally listed on Amazon for £99, so I had to buy them too lol.
It occurred to me that the firmware on the NC800 is identical to that on the DS-2CD2387G2-L(U), making it simple to upgrade to the most recent Hikvision firmware.
When comparing the nc800 and 4k-t, I discovered that the results were very similar to what I saw in wildcats Comparison video between the 4k-t & DS-2CD2387G2, for me the 4k-t is a better camera with its manual shutter and gain settings and for my needs at capturing number plates at night with a faster shutter speed it was able to give a good overview is well where as the nc800 would struggle at that shutter speed making it too dark to use.
Interesting because I find the POE+ connects reduce any interferenceThe noise that was in the audio captures I posted was with the camera connected to a new PoE+ switch. Surprisingly with the power supplies the noise was about half as loud.
Yes I absolutely advocate for managed switches. To be fair I use those in deployments anyway but even personally I have a complex NW infrastructure. I use for segmentation and security across different traffic profiles and in the case of cams, yes, isolate and then control bandwidth as well. Also the logging functionality is incredibly useful toohi @Wildcat_1
A bit off topic, but do you find the managed POE switch better for your needs?
Do you use it to ease the traffic of the cams on your LAN? security?
I was thinking about BI computer with two NICs that would be the gateway from the LAN to the cams. does that make any sense? is that how you're using it?
At least these issues are firmware related instead of hardware.For the Issue pixel & chip processing issue of the 4K-T , we have another newer firmware to be released very soon, has some good improvement based on the 20220923 version for the pics.
Right now can do the testing, anyone want to try just send me DM.
