Don't look for the latest FW.Hey yall, just wondering is "V2.820.15OG001.0.R.210525" the latest firmware?
Don't look for the latest FW.
The two FW from 2021 "fixed" SMD 3.0 but broke the good IVS.
As a result, the SMD is not detecting human as the IVS but the IVS started failing too many times.
There are false positives as well as false negatives.
The IVS is way more important so my advise: stick to Dec. 2020 FW.
Indeed. I have a set of one metre poles in the garage just for this.Be sure to always perform this for best results: IVS/Global Setup - Dahua Wiki
But yes, I see missed IVS events with the July firmware. Just had one occur, completely missed a large garbage truck.
I'm using 4X5442T-ZE and 4X5442E-ZE (8 cams).@ArnonZ both my 5442-ze and 5442-ase 3.6mm are running fine with the latest July firmware, I’ve not noticed any missed IVS events?

Yes, the image looks good enough to trigger IVS when it's just skipping the detection.So far I am not impressed with the IVS triggering with this version of software. Ironiconly, the camera that did not trigger, was the one I calibrated with IVS global setup. Yes, I checked calibration. The others that worked, I did not have time to calibrate IVS yet. If worse comes to worse, I am going back to triggering with BI zones. At least I know where I stand and it worked for years.
I am also not impressed with the new smart IR

@looney2ns :
I am going to change two 5442T-ZE cams with 5849 cams tomorrow.
Though I was asking before, I wanted to make sure that the issue does not exist there.
I was afraid that it might be related to the SMD 3.0 that the 5849 use from day 1.
I'm asking you as the most experienced guy with those two models, as the #1 expert, as the first one to test the 5849 and as someone that DID find the IVS problem with the new FW of the 5442 model.
I do need the IVS more than all other features.
I have 6 Dahua 5442 cameras and upgraded 3 of them to the latest 210729 firmware. I am using IVS intrusion box (human) to trigger Blue Iris. This firmware works good during the day, so far, but testing at night gave poor results or none at all. The cam that did not trigger, had good contrast at night and a good view of a human. I have 7 years experience tweeking Dahua cameras for best resolution, day/night. So far I am not impressed with the IVS triggering with this version of software. Ironiconly, the camera that did not trigger, was the one I calibrated with IVS global setup. Yes, I checked calibration. The others that worked, I did not have time to calibrate IVS yet. If worse comes to worse, I am going back to triggering with BI zones. At least I know where I stand and it worked for years.
I am also not impressed with the new smart IR. That option did not illuminate the area enough to see targets well, even after adjusting shutter, gain, brightness, etc. It seems Way to sensitive. I have disabled smart IR and went with Manual setting.
@ArnonZ or anyone, where can I find the Dec. 2020 FW?
Downloads top of this pageAnyone, know where to find the Dec. 2020 FW? @EMPIRETECANDY
Thanks @Wildcat_1(see my review thread) uses a different FW and currently although still has some issues to fix that I raised, is overall pretty stable and the image is improved too. Have not seen issues with regards to IVS misses on SMD
I'm using 4X5442T-ZE and 4X5442E-ZE (8 cams).
Using the May FW, I started getting my dog caught for the first times in a year.
Not only that, I started missing IVS events.
reverting to Dec 2020 FW, I no longer get any IVS events from my dog (there was one exception when he was walking on two legs at midnight).
Unlike NielK, I didn't (yet) find any relations to the time of day.
I can tell you that it's not "only" me, NielK and looney2ns that saw that phenomena. it was mentioned here few times.
I did not try the Jul FW because I was told in private that the problem exists.
I do not care too much about the SMD3.0 as even when I did use the May FW, it was not as reliable as the IVS for both human and vehicles.
I can tell you that even if you didn't see an IVS performance issues, more likely that you are simply not aware of the events you were missing here and there.
Ref: FW dated 210729Certainly a shame to hear about your experience @handinpalm, I actually find the SmartIR is much more on point in the 7/29 release with the adjustments made to combat washout that was very much present before. Since you stated you already tried global config, I thought of some other areas you might try. Couple of things that come to mind that you may have already tried but will list:
Again, just some additional thoughts. I know you know your way around your cams but if you want a second set of eyes and want me to take a look at the dial in, you know I'm always happy to help where I can. Just send me a DM and we can chat.
- Ensured full reset before and after upgrade ? As I detailed in my findings with this FW in 1 case I had to reset a total of 5 or so times in a row before getting the 5442 to finally start acting right with the FW. I made some notes on a best practice to follow when doing so which reduced the number of resets I had to do. Ending result was more on point SmartIR + SMD/IVS. This issue of the multiple resets I saw across multiple units as I reported
- Have you tried SMD to see if that is accurately capturing Human vs Vehicle targets ? If not try that and see if that is able to capture correctly for you in the same environment. Would also help fault isolate to specific IVS issue or target acquisition in general for your cam(s)
- If setting up through Blue Iris, have you isolated the camera (off of BI) to see what it is/isn't capturing live and to local SD ? For example, in realtime are you seeing target boxes drawn, anything captured to local SD etc ?
- Have you tried adjusting target filter sizes for human's in the IVS config ? Depending on the FOV, distance to target etc, sometimes this can make a big difference on picking targets that were previously not detected. It also forces the camera to re-think what it see's as a target
