Hi,
I updated my camera 00030679.1 XM550_80X50 to General_IPC_XM550_80X50.Nat.dss.OnvifS.HIK_V5.00.R02.20200707_all.bin, but the PTZ stopped working.
When I want to install the old firmware version General_IPC_XM550_80X50.Nat.dss.OnvifS.HIK_V5.00.R02.20190730_all.bin, an update fail is displayed...
