I just discovered with the toolbox that both devices are on FW version 1.000.0000.0.R
On the international Dahua site I found newer versions of the FW for these devices, DH_VTOXXXXD-G_MultiLang_PN_SIP_V4.400.0000000.9.R.20200326.zip & DH_VTHX421H_MultiLang_SIP_V4.410.0000000.4.R.20200221
Is it safe to just upgrade or are there risk involved which are more then normal when upgrading the firmware?
