Keep in mind Hik's Lux ratings for this camera are a t F1.6 (colour Lux 0.05)
Hik 4MP exaples here are rated 0.01 @ F1.2 (bigger iris) however this PTZ out performs the 4MP.
The new 3 & 5MP are 0.005Lux @ F1.2 (more iris light) so you can't directly compare them on paper although a rough conversion, there is about 0.8 iris difference - i.e. F1.2 is about 80% more light then F1.6 so if you adjust the Lux rating by 80% then we're looking at 0.008Lux for this PTZ - dosn't seem so bad to me...

Way better then the old 3MP's, I had those all over and the 4MP was better then those making colour night vision a real possiblity - the jump in night time IQ with this PTZ which may well share the same or similiar sensor as the new Easy IP3.0 camera's is a similar of not bigger leap.

Yeah I live on the Wirral, the lights on this street are those dim amber sodium lights (you know the ones that start of red when they first come on) - old fashioned concrete lamp posts - one every hundred yards or so.
But don't let the pictures fool you - the street looks better illuminated under both the 4MP camera and PTZ shots then in real life, reality is about half of what the the 4MP looks like.

Interesting Bick. I recently got a camera (different model) and the IR cut filter failed within a week. It is a DS-2cd2542fwd-is. One out of there I bought failed. Thinking Hikvision may have a manufacturing issue on some of their newer cams.
Strong argument for buying from dealer. Returning my camera bought on AliExpress is economically unfeasible.

What are the symptoms of it failing- particularly it fails with the filter disabled? I'm guessing if it fails with the filter switch on you lose night IR capability?
I got it working yesterday. There is an on/off checkmark option on the camera's config page (not BI's config, but the camera's config page). Then make sure the trigger setting are appropriate to catch movement -- and autotrack works.
That's the button. I adjusted the motion sensor setting way down (on trigger tab) in BI and that got it working. Min object and contrast way down and .5 min duration.
On the trigger tab, hit the config button next to motion sensor. Should have two sliders for min object and contrast along with a value for min duration. I'd take a pic, but don't have a print screen on this computer.
