All, I finished my testing of this 09/08 FW and wanted to give you all an update on my findings.
Overall,
this FW definitely improves on the camera responsiveness (doesn’t feel as sluggish as 7/09 & 6/11 in menu or under strain)
+ the adjustments to AA that I mentioned earlier are a BIG benefit to PQ here. However, there are still some critical issues so I thought it would be easier to revise the original bug list (9 items) + the extra 3 I raised to Andy after continuing my original test. This way I can easily show whats fixed vs outstanding.
Bug List Filed With Dahua - Updated for 09-08 FW
1. SD Cards Could Not Be Read + FIXED
2. IVS Rules Would Not Capture / Trigger Video = FIXED
3. IVS Rules Would Not Allow Appears & Cross To Be Selected = FIXED
4. Object Monitoring Rule - FEATURE WILL NOT BE ADDED BACK UNTIL LATER - TO BE FAIR THIS IS A BONUS SO NOT A BIG ISSUE IN MY OPINION
1. Object Placement Would Only Trigger Recording On Boxes Consistently, Not Other Items
2. Object Removal Would Not Detect An Object Being Removed From The Scene
5. Camera Would Not Adjust Correctly For Contrasting Scene/FOV Where Shadow Area + Well Lit Existed In Same FOV - Affects Day & Night Scenes (ref. WDR in day video) = Partial fix in shipping FW but next fixes expect in ‘Wildcat tweaked’ version = FIXED
6. Illuminators on Auto Would Only Come On When Target Was Within 2-3ft of Camera = FIXED
7. Illuminators Turn On & Off Briefly When Set To Manual And Target Is Close To Camera = FIXED
8. Custom Video Bitrate Does Not Survive A Reboot = FIXED
9. WebPlugin Used on Color4K-X Impacts Older 4K Plugins Causing Blank Screens in IE and Re-Download Prompts. Impacts 1831/2831/5831 models = STILL NEEDS TO BE FIXED - EXPECTED IN WEB 5.0 FUTURE RELEASE
10. Exposure settings (primarily when using variable rate) would revert on logout on 7/09 FW = FIXED
11. Frame rate anomalies (31 frames seen in 30fps caps etc) on SD card + NVR recordings = STILL PRESENT, NEEDS TO BE FIXED
12. Auto Gain Circuit (AGC) & Auto Iris too aggressive = STILL PRESENT, NEEDS TO BE FIXED
I mentioned # 11 before and what I saw when I analyzed numerous captures. Some people had asked about this and even Dahua wanted further information showing this was actually a thing. and whether this could be possible. I can assure you that it is and actually in testing night time on the 2.8 for 09/08 saw it in action again. I’ve created 2 clips (in the video below) to show what happens here. 1 clip is where there is an extra 2 frames added (32fps when set to 30fps) and then a 2nd clip that shows frames missing, 27 fps (still when set to 30 fps). I’m only seeing this on the 4K-X cams and it is definitely on cam as it affects both local storage capture (SD card) + stream to NVR. I've tested this many different ways across various pieces of kit both with isolated NW configs (monitoring traffic etc at the same time), multiple SD cards and while the issue is random in nature, its definitely still there. This doesn't mean every second will have this OR that every cap will see an issue BUT it is still present (has been and I've confirmed on 6/11, 7/09 and 09/8)and needs a fix. I've communicated this latest update and video back to Dahua engineering for further analysis and made
@EMPIRETECANDY aware too, thanks Andy !
As mentioned, I’ve captured 2 x 1 second clips to show this in action. I know some may say I take this job too seriously BUT in doing it this long, I like to think I’m detail oriented
. I've reduced the speed and overlaid a frame counter for you to assist. This issue either points to performance related on cam (i.e. gets to a bottleneck) OR encoding algorithm. As I see potential ‘blips’ on both in code, will need Dahua to run to ground as I’ve highlighted with them.
