Artifacts! (not the good kind)

Recently added a Hikvision DS-2CD2185FWD-IS (firmware: V5.6.3 build 190923, Encoding: V7.3 Build 190910) to my Hikvision DS7608NI-Q2/8P NAS (Firmware: V4.30.085 Build 210409. Encoding V5.0 Build 210406)

I have the camera to record on motion only.
I access the NVR using Internet explorer and play the stored motion clips.

The mailman walks up to the mailbox beside the front door. There is a little pixelization in spots as he walks through the frame, delivers the mail and leaves. After the mailman's physical body has left the yard and carrying on his route. His image reappears (headless) and standing frozen in motion in my yard as the camera captures me exiting my front door a half hour later....
In other words, the artifact of the mail man carries over into the next stored motion capture of me leaving my front door.
This is repeatable every time I play the clips.
However, As I forward and start playing only the motion of me leaving my front door, I am missing part of the image of me walking down the walk and turning the corner.

This is only happening on the DS-2CD2185FWD-IS camera not on any other camera I have.
I bought this camera used.

Anything anyone has run across before?

8MP does not work on a DS-7608NI-Q2?
Needs an SD card?
Got taken on the purchase?

How many other cameras are connected, and what is the aggregate bitrate? (NVR has an 80Mbps incoming spec)
What codec is in use on the DS-2CD2185FWD-IS? (h.265+ can be quirky)
Do you see the same symptoms on the VGA/HDMI interface of the NVR? (PC connected over WiFi / maybe struggling with decoding/redering of the video)
 
Cameras are connected directly to the POE ports on the NVR and obtain a 192.168.x.x IP Address handed out from the NVR
I am accessing the playback through the wired LAN 172.29.X.X IP address handed out by my router DHCP server.
The NVR has a static IP address programmed into it.

There are five cameras total at present. Four are DS-2CD2143G0-I and one DS-2CD2185FWD-IS

Things were ticking along just fine for years with five DS-2CD2143G0-I cameras and the older "release 3" firmware (exact version unknown) I upgraded the firmware and changed the one camera.

H265+ is on

On the 4MP cameras Max bitrate is 3072, with the max average bitrate of 1536 Variable bitrate with highest video quality 3072, resolution 2688*1520, Frame rate 30

On the 8MP 16384 max bitrate, Variable with highest video quality, 20 frames/sec (maximum) I had H265+ on but have changed it to H264 max bitrate 16384

Not entirely certain what the camera settings should be. It just seems like there should be headroom with the existing setup since there are only 5 cameras. with only one of them being 8MP
 
I think most of us find the best results when we turn off any "+" on codex's. So try H265, not H265+. Also, while H264 does require slightly more hard drive space than H265, it seems to be a more stable codex and it's generally recommended over H265 for CCTV use. I'd also recommend using a fixed bitrate and not a variable bit rate. Again, this might require slightly more hard drive space, but the results will be much more stable. If you are recording only on motion, I would not worry about the extra hard drive space these changes would make. You would have a hard time even measuring a size difference between the old and new settings.

I'd try those two changes and see if it helps.

And follow the motto of many here - if the cameras are working fine, do not update them. It usually breaks things.

Here are issues I have seen people report here where they were upgrading just for the sake of upgrading:
  • A Dahua Z12E that someone updated and then constantly reboots comes to mind,
  • The Dahua 49225 and 49425 PTZ that loses autotracking with an update come to mind,
  • A Hikvision ANPR camera losing half the FPS and loses the ability to read US plates - those are big deals to have happen.
  • A Hikvision camera that the user lost ability to control the LED light function at night.
  • Hikvision wifi cams that lose ability to work with Hik-Connect if updated.
  • Countless other instances where the camera simply bricked and became useless.
  • Countless examples where the camera went into Chinese.
Don't do it unless it is fixing a problem you are experiencing or adds a feature you really need.

Yup, this came to me too late......

Perhaps my experience can serve as a warning to others.....

My real motivation was security concerns. Perhaps unfounded....

Much has changed with the update. Such as moving fundamental configuration from the NVR itself to the web client.
Most of what I was able to do in the NVR HDMI output is no more....
