Thanks for this and Parleys post, I also had a crap picture on my 4MP DS-2CD2047G2 rear camera and took it apart to Re-focus it although the insides were different and required removing 2 mini pcbs to get at the lens the results are much much better Pics below

I agree, a much sharper picture.

Do you have any pictures of what it looks like inside as curious why it was different?

 

[Logan555]

I dont unfortunately but its quite different with the focus ring being right on the end of the lens hence having to remove the lens assy completely from the body and plugging in the little pcbs and power and setting the focus before putting everything back inside the body, It wasnt too difficult just abit fiddly with tiny screws inside. What did surprise me was inside the body was one of those little mosture absorbing bags.

Mine had two of the moisture absorbing bags.

Yes, those bags better replace every 6-8months. though the camera is seal well, but can't be totally sealed. So need those bosorbing bags.

Andy does there exist a 1/1.2” sensor 4MP camera yet ?

not yet, the 4K ones chips also has big problem for the supplying, i think have to wait after 2022 at least.

ADT thinks they own all blue-ish octagons huh?

Time to get your trademark registrations in for more basic geometric shapes before they're all gone!

Just revisited this at a reasonable time of day now that I'm more awake, and the focus improvement looks better front to back.

I think someone should feed this back to Hikvision because the performance of their cameras is being seriously degraded by the looks of it by poor focus setup at the factory.

 

[shapin]

Is the 2.8mm suffer from that bad focus too?
If so what alternative do you guys recommend?

 

[CCTVCam]

Full disclosure I don't have one but from what I've seen I don't think you'll be disappointed with the camera out of the box. It could be better but it's by no means poor to start with.

I wouldn't hesitate to buy one if I had the money to hand.

 

[Parley]

As I said earlier, I have 4 of them. 4 of the 4MM's and one of the 6MM's. Two of the 4MM's were perfect right out of the box. One 4MM and the 6MM I had to take apart and fine tune the focus. It is not hard to do if you are mechanically inclined. However as stated above it is something that the buyer should not have to do. It is a fine camera and I would buy another one if I had a place for it, and that is its saving grace. However I am waiting on the Dahua version to try out.

My 2x 2.8mm have perfect focus.

 

[Maconi]

How much of a close-focus difference is there between the 2.8mm and 4mm in the real world? I had originally purchased some 4mm's based on DORI but I looked over the huge focal range difference between them spec-sheet wise (4.5m vs 7m close-focus). How much worse is the 4mm at focusing on close objects vs the 2.8mm (does "out of focus" mean unidentifiable or just slightly imperfect focus)?

The Hikvisioneurope.com Portal doesn't have a link for firmware 5.5.800_210628. If you don't mind me asking, what version were you able to successfully upgrade to?
