I purchased an Empire Tech NVR5208, and while everything definitely looks like Dahua NVR there are some very obvious things not the same. The whole events section is missing from the UI etc. I did download the DH_NVR5XXX-I_MultiLang_V4.001.0000000.2.R.200814 firmware from Dahua and uploaded the DH_NVR5XXX-I_MultiLang_V4.001.0000000.2.R.200814.bin into the firmware upgrade section of the UI. It rebooted, but the UI wasn't updated. Anyone have any ideas on how to get the NVR fully functional?
