Hi there,
I've a dahua DHI-NVR5232.
The system shows the version as 3.200.0000.4 build: 2014-11-4.
I asked support for the firmware I've to download from their website; http://www1.dahuasecurity.com/firmware_171_1.html
They said i should use DH_NVR5xxx_Eng_P_V2.616.0000.0.R.20150316
I downloaded it but the system says "Upgrade failed".
Any ideas? Anyone has a link for correct firmware.
