Dahua DH-SD42212T-HN firmware upgrade issue

[loicremy 0]

Hi,

 

I have an issue when atempting to upgrade this PTZ camera.

Actual software version is : 2.400.0000.9.R.4, Build Date: 2016-05-25

 

I downloaded last firmware 2 files on Dahua website :

DH_SD-Mao-Rhea_Eng_P_Stream3_IVS_V2.600.0000.2.R.20170905.bin

General_SD50XXX-HN-MAIN_MCU_V2.300.0000000.10.R.170926.bin

 

When I started upgrading with first file,after seconds, I got the 'File unmatch...' error, camera rebooted, the software version was the same and all camera functions stayed ok.

 

Unfortunatly, I made the upgrade with the second file, got no error messages, camera reboot but since that, PTZ commands are not working anymore.

 

What could I do to solve that.

 

I noticed the ' (-S2)' mentioned at end of product name on Dahua website. What is the meaning of that mention? Is there a difference with my camera ?

 

Thank you in advance for assistance !
