@Mint St8t Farm Hi, actually I am logging into the camera interfaces directly. I can make the configuration changes there or within Wave, which then sends them to the camera. Either way works and its bi-directional. Both ends are showing the 2 top resolutions that go over 5MP and I wonder why the firmware would include that if its not valid for the model. Perhaps Hikvision made a generic firmware for various models including 6MP and just assumed that plonkers like me wouldn't use a resolution that the camera doesn't support 😝

I wonder if its somehow scaling down but Wave does display the stream info as being 3072x2048. Or maybe its just displaying what it thinks its set the resolution to. Anyway I'm glad you pointed this out and I'm dropping all my cameras to 2944x1656, which seems to be the max to stay under 5MP. I can't see any loss in quality so I'm fine with that. Thanks for your help. Alex

@Andy DyDy PS. I'm using WiseNet Wave as my NVR and I have the option of doing the camera settings in its web interface or within Wave and that flips the settings. At either end 3072x2048 is a valid option.

@Andy DyDy Ah! That's a very good observation. 🤓. Thank for doing the maths. Funny that it didn't complain before when in landscape 3072x2048 However I'm setting the resolution directly in the web interface and you would think that only valid resolutions would be listed by the camera's firmware. Now you're making me wonder if I've somehow got the wrong firmware in it !

After months of wondering about this and not finding any explanation for this message, I have found an answer (sort of). The reason I want to retain portrait mode because that covers the specific areas much better. It seems the Rotate option fails if the resolution is set to 3072x2048. Anything below this and you get a Save successful" message and the stream rotates by 90 degrees. Unfortunately for me, this is in the wrong direction and the images are now upside-down but I can deal with that by getting up the ladder and rotating all the cameras 180 degrees. (For reference, the correct way up needs to be with the the camera lens above and IR below.) Its a pity the Rotate function doesn't give the option of 90/180/270 degrees. So to confirm, I'm using 3072x1728 H256+ and that's okay. Just a bit narrower than the images were before. I hope this information may be useful to others.

I'm using 3 turrets (DS-2CD2355FWD-I) in portrait and I want to rotate the streams rather than turn the displays in the client app. If I try the Rotate option in the web interface I get this message for a second and nothing happens. "Encoding performance reaches its limit". I tried Googling for that but not much useful found. Turning off H265 didn't help Anyone have any ideas?
