Firmware for newer dahua cams as well as detailed specs available here

[Perimeter]

I have an IPC-HFW2231S-S-S2 and found two different actual FW files.
DH_IPC-HX2XXX-Molec_MultiLang_PN_V2.820.0000000.49.R.220815
DH_IPC-HX2XXX-Molec_MultiLang_NP_V2.820.0000000.49.R.220815

Their only difference is the PN vs NP. What does it stand for? PAL_NTSC and NTSC_PAL ? Is the first letter the reset default?

That is correct. It doesn't matter. When you specify the country at initialization it will set the correct one. If not it is just a toggle.

What kind of Chinese logic is that anyway. Different firmwares just for two different default settings??

I just saw it on the link that you yourself posted. There's a new one there from Aug 2nd.
Not sure if Andy has a different one.

There was another General HX5XXX one posted there on July 28th (although the README only lists "HFW52XX,HFW54XX").
Andy said he would post a new one here soon, but that was over a year ago.

My apologies if this has been asked - I have not read all 12 pages of this thread.

I have two questions related to firmware identification. The first is general while the second is camera-specific.

1. Both Dahua's and EmpireTech's firmware listings include two different dates. EmpireTech has "Build Date" and "Lastest Time". For Dahua's site you can see the build date at the end of the filename and then a "Last Update".
How is the build date related to the other date? What has changed since the build and why isn't that considered a new build? Once flashed to a camera, only the build date is readable. How would anyone know which update it is?

2. I recently got an IPC-B52IR-Z12E-S2. It came with "V3.100.0000000.5.R, Build Date: 2023-05-09" flashed. Looking for updates reveals these available firmware versions.

From Dahua with a note about "S3" IPC-HFW5241E-Z12E - Dahua Technology
- DH_IPC-HX5XXX-single-RiemannMultiLang_PN_Stream4V3.100.0000000.6.R.230802.zip

And from EmpireTech where I am similarly confused regarding "S2", "S3", or "". The filenames are the same but appear to target a different "architecture" than the Dahua file (Volt vs. Riemann).

Model	Lastest Time	Build Date	Filename
IPC-B52IR-Z12E / IPC-HFW5241E-Z12E	2023-07-18	2023-04-25	General_IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.840.0000000.25.R.230425.bin
IPC-B52IR-Z12E-S3	2023-09-11	2023-08-02	General_IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.840.0000000.25.R.230425.bin

Which version is correct for my camera? I'm leaning toward Dahua's Riemann given the "V3.1" that matches what is currently flashed.
Is there a difference between the two EmpireTech files given the different "Lastest Times" and "Build Dates" that would make one compatible with my camera and the other incompatible?

quelqu'un a déjà essayé le nouveau firmware et le logiciel PTZ ?

Bonjour à tous, je cherche le dernier firmware de la caméra : DH-SD59220S-HN. Je n'arrive pas à le trouve. Bien que ce soit du matériel ancien et que votre question soit ancienne, si quelqu'un pouvait m'aider, cela serait sympa.

I just tried to download the firmware for Dahua IPC-HFW2441T-ZS and got the "Not Found / The requested URL was not found on this server.". I then tried some other cameras and it was the same for them, too.
I'm not sure how long this has been broken like this for, but here's what I found out:

Original (broken) link on Dahua's website is:

https://www.dahuasecurity.com/asset/upload/uploads/cpq/SWR/2564467/M/DH_IPC-HX2X4X-Taylor_MultiLang_PN_V2.840.0000000.15.R.240323.zip

I then went to archive.org to see how URLs looked like when they were still working. They were indeed different so I changed the first part of the URL which then worked and gave me the file:

https://material.dahuasecurity.com/uploads/cpq/SWR/2564467/M/DH_IPC-HX2X4X-Taylor_MultiLang_PN_V2.840.0000000.15.R.240323.zip

Hope it helps someone.
