Is it known if the Color4K-T camera is utilizing the newer Sony IMX585, over the Color4K-X's IMX485?
I'm 100% sure that HDW5849H-ASE-LED isn't IMX585
I the answer from the firmware decrypted.
Color4K-X is sure to be IMX485.

I just got the color4K-T installed and after some fiddling of the parameters it gives a very nice image, so i started with the IVS parameters but encountered some strange things, not sure to what this is related but perhaps other people can relate.
So I've got a NVR type NVR5216-4ks2 with some old cameras and the new turret one.
In the past i used to run on motion detection and IVS recording on event to reduce the storage usage but i'm changing towards continuous recording.
Nevertheless my old camera's (5231 & 8232) worked fine on motion and IVS events and I could use the IVS search feature to quickly scroll to all events.
So I changed my color4K to continuous and put IVS rules on the NVR, for some reason i don't see those IVS rules in the camera even though they are there?
The downside of motion recording was the too late recording but was not really an issue for the purpose, now however with continuous recording i'm wondering if the results I see are as intended:
You have to put a recording on the IVS rules otherwise you don't get any bookmark.
If you put a bookmark the NVR still does record a 15second (configured time) time video which stops the video on the normal recording, this leads to potential loosing 1-2 seconds of video data. how can you avoid this?
In general the IVS detection is mostly too late, can you put a minus delay on the detection so you can have at least a video of the whole detection period?
For some reason i can't use the IVS search feature on this camera, this morning it worked for 2 hours then stopped. So does anyone got this working?
Does anyone use SMD actually on this? but it seems the IVS uses the SMD (human/vehicle) to filter out, so that's fine by me either.
Perhaps a bit too many questions but i'm just wondering if this is the expected behavior or if there are still some bugs underneath?
Thanks.

Be sure to setup the camera from within the camera GUI it's self, not within the NVR.
Be sure that you are using Internet Explorer to do the camera settings.
Yes, it is still buggy.

ok i found the ivs page on the camera, didn't look at the "home" tab like on the nvr 
everything seems ok as on the NVR, nvr config is correctly pushed to the camera.
I've checked the IVS search in the NVR and the strange thing is that it seems to be linked to the day/night schedule in the camera for image settings. Anyone else got this also?
Just wondering how anyone else configures their camera to the regard of continous recording as it currently drops a few seconds as it starts to record the ivs event, if i don't configure record i don't get any ivs mark on the timeline.

I record 24x7 and IVS events. I have never found a way to get the minus delay on IVS detection, which would be a huge improvement. As far as losing frames on IVS triggers goes, this was a problem for me a few years ago with the V3 NVR firmware, and it finally got fixed. Has it crept back into the firmware? I'm running a pretty old version of the V4 firmware that's working pretty well for me. On an IVS event, the NVR closes the current video file and creates a new one, then does the same thing again when the IVS event ends. They are in effect using the linux file system to index the events, which I doubt I would do if I were doing the design. I do my viewing with smartPss, rarely using the NVR's web or local interface. I vaguely remember with the web interface that the IVS events aren't visible on the timeline without some zooming. I have a V1 5216-4ks2.
Anyone having any luck with SSA? When I turn it on I get a very greenish image. Full sunshine today and can't see much of what is in the sunshine area. With SSA it would be more decent but color is no good.
Also is everyone having audio issues where it seems to randomy swith between codec or I don<T know what. 1 minute it's ok, (despite not the best audio anyways) and then sort of swithches to a muffled type sound. very weird but annoying when you need the audio.
I'm on V3.0.20.R, Build Date: 2022-09-26

Looks like Dahua has now released a new version of firmware for this as of 01/05/2023. I just loaded it to try to see if it resolves some image digital artifact issues I was having at night with low light and it has majorly improved the low light image quality/3DNR pixelation issues. I am going to reach out to Andy to see if he has an updated version with his firmware that has these same changes in it.

The new 2023 firmware i am asking @Wildcat_1 to test. Has some improvement. Will release soon if good.
Also noticed an improvment in the audio quality, and can now see live views in the camera's UI using Firefox & Chrome.

Applied it earlier today, thanks for the heads up. UI seems a bit more stable and responsive. Audio great. So far so good
I can work with that, but what if you are running Linux? Are you just screwed? My current Dahua's started working much better after a firmware update years ago with Chrome/etc, but what are the limitations on non IE browsers for this camera?
Testing this on multiple units and will report back
You're partially screwed. I've successfully done some camera configuration with a linux browser. How much depends on the browser and the camera and its firmware. I haven't tried pale moon on linux. The windows pale moon operates the 4k-x pretty well, but with very slow response. If the linux pale moon needs a plugin that doesn't work, its usefulness would be very limited. Sorry I never tried it yet, haven't had the need so far.

Andy, is there any news on a variable focal length version yet?
Also, anymore interesting cameras for 2023 with large sensors?

As we used to say on the ship, 'belay my last'.
Audio has reverted back to it's metallic, over driven screeching. First test after update & reboot all good, checked later and back to crapola.
Still no plan on the motorized lens.

Getting the hang of it
Why there is such dependency on internet explorer considering it has been on the list to be completely dead for a few years already? Microsoft already ceased support for it for quite some time, the whole world has moved on to Chromium. It seems odd to me to have such nice hardware with firmware that relies on something that is completely discontinued. Edge based on chromium has been around for 4+ years now, chrome has been around forever.
