    HDW5442TM-AS – Washed-out image with IVS on latest official FW – Is downgrade to SmartIR possible?

    HDW5442TM-AS – Washed-out image with IVS on latest official FW – Is downgrade to SmartIR possible?

    Hi Everyone, I have several IPC-HDW5442TM-AS cameras. All of them have been running the latest Smart IR firmware by EmpireTechAndy: V2.840.15OG00D.0.R.220818 On one of them – an older HDW5442TM-AS model – I decided to switch to the newest official Dahua firmware (hoping the updated IVS...
