So far, my I wanna use the NVR incoming bitrate to service 16384 channels aint working...
Why? It's handy to be able to access that directly, without going separately into the cameras own menu.and Camera/Video Parameters/Main Stream has "I Frame Interval" setting... more disappointment there
I had noticed this problem before but hadn't noticed it was fixed... that's good.On the local menu - Maintenance > Camera. In the camera list Motion detection used to be incorrectly shown as "Not Used" on all AcuSense cameras - it now correctly reports "Used" (where motion is enabled)
Camera/Video Parameters/Main Stream has "I Frame Interval" setting... more disappointment there
My mistake here, you are right, it is handy and it does work correctly... where I actually seen a new issue was on the sub-stream settings page... when I make a change there, sometimes after an NVR reboot the camera's sub-stream max bitrate changes to 4096 Kbps and the sub-stream won't load... I have to log into the camera directly and reset it there... not a big deal just a nuisance.Why? It's handy to be able to access that directly, without going separately into the cameras own menu.
This is the real issue I'm having but I was a bit rushed when I posted this and wasn't clear... using V4.51.025 I was able to run seven 8MP cameras at 16384 Kbps max bitrate and playback was smooth... on the 4.6 versions playback on the NVR stutters unless I lower the bitrate to 8192 Kbps... on another thread, @r44flyer reported a similar symptom:So far, my I wanna use the NVR incoming bitrate to service 16384 channels aint working...
But he also noticed that playback on iVMS-4200 was still smooth and I checked then, and this is the case for me also... so the camera stream is being recorded correctly but playback on the NVR itself stutters... I was hoping this V4.61 release would fix that but it did not.Minor niggle, NVR playback on higher mega pixel cameras jumps at what appears to be the pre-record buffer point and isn't as smooth as it could be.
However on iVMS playback directly from the NVR on a wired network is very smooth.
Yes I remember reading that other thread. I've not seen it on the newer cameras but I do have some stutter issues on a couple of 8MP G1 platform cameras. It occurs during motion as described but only during the day, never on a night. Those cameras are DS-2CD2386G1.But he also noticed that playback on iVMS-4200 was still smooth and I checked then, and this is the case for me also... so the camera stream is being recorded correctly but playback on the NVR itself stutters...

The cameras I have stuttering on are DS-2CD2387G2-LU (G5 series) and DS-2CD2087G2-L (G3 series)... only when set to 16384K bitrate and only on the NVR playback (iVMS-4200 playback works fine).Yes I remember reading that other thread.

I don't have the issue with the G5's. For reference, my DS-2CD2387G2-LU G5's are set to 25 FPS @ H265, 12288K bit rate (VBR), highest quality with the I frame set 25.The cameras I have stuttering on are DS-2CD2387G2-LU (G5 series) and DS-2CD2087G2-L (G3 series)... only when set to 16384K bitrate and only on the NVR playback (iVMS-4200 playback works fine).
I going to try your settings (currently I'm using H.264) ... are your cameras set to PAL or NTSC? Mine are NTSC and I think 24 is the highest frame rate?I don't have the issue with the G5's.

Mine are set to PAL. I briefly had one of them set to NTSC as it reduced some image issues caused by some external LED lights that I have. I always mention it but be sure that in Storage > Advanced that you have Pre-Record at 0 seconds (if you're recording 24/7).I going to try your settings (currently I'm using H.264) ... are your cameras set to PAL or NTSC?

The latest on the portal 4.60.005 is fine.Which firmware version do you think is the best for this NVR?
Thanks for the update @DanUPDATE - Hikvision Support has responded to me saying they were not aware of the issue and they are now testing the firmware at their end, if they can verify the issues reported here they have said they will temporarily remove the v4.61.000 firmware from the I-series product pages until they can resolve the issue.
