No it will not work, don't make any try or else brick your PTZ. Only for the SD49225XA-HNR or SD49225XB-HNR.Hi, does anybody know if is there a firmware to enable auto track on Dahua SD49425GB-HNR?
Is no chance to find a firmware for SD49225XA-HNR-S2 to work auto traking?
Now i have: 2.812.0000007.1.R, Build Date: 2021-07-13
PTZ Version 2.401.0000000.64.RHNZ 200219 34642

Onest, i thought S2 is newer model. 
Unfortunately is too late to be returned...it past 14 days.
P.S. Because of hardware of S2 is not possible to flash the firmware? In the future is not any luck?![]()

Hello! The link is no longer valid unfortunately, could someone upload it again?
Andy's website link for the SD49425XB-HNR firmware still works. I just tested a minute ago. Once you click on the firmware you choose it will open another page, and then make sure to click on the arrow icon on the top right corner on the new page to download the firmware.Hello!
