I updated my NVR5216-4ks2 today from 4.002.0000000.5 to 4.002.0000000.6 (dated 15.11.2022) which I downloaded from dahuawiki.com/images/Files/Firmware Unfortunately does this "new" Firmware not remove the bug which I had reported to DAHUA through dealer and distributor. There is also no release...

"My" dealer seems to have downgraded to another 4.002.x , i will try to check tomorrow.

Firmware downgrade impossible if from 4.002.x to 4.001.y told me "my" dealer in Germany and another outside Europe. That downgrade-block seems to be for technical protection of the NVR. Similarities with other models and firmwares from other manufacturers. At least I came to the conclusion not...

Did you report the problem to the dealer in writing (email) from whom you had bought the NVR? When and in which country had you bought the NVR? Had the problem already been there with an older firmware? My NVR had earlier a firmware 4.001.x from summer 2021 and that older firmware had no...

Hello People! According to info which i have received today from a dealer - who had received the info from his distributor who got the info from DAHUA - has this firmware a fix for the problem reported by ME recently. Means that the NVR should no longer loose the configuration regarding the...

Thanks for the link!!! According to my todays knowledge should this firmware at least fix the problem which I had reported to DAHUA via dealer/distributor, namely the configuration loss regarding external alarm input (at ipcam) after powerloss of NVR. Whether this firmware fixes also other...

Did you rollback from 4.002.xxx to 4.001.yyy ? Did you use the HDMI-interface (with a monitor) or the LAN-port and Weblogin thru the ip-address of the nvr and a windows-pc?

how did you roll-back? I got also a problem and need to t Excuse me, but which interface you mean - HDMI or LAN

how did you roll-back? I got also a problem and need to t Please forgive me that I ask some more questions... USB-stick formatted by fat32? With "NVR interface" you meant the HDMI or the LAN (RJ45) port? The NVR might have more than one USB port - which one you used? What do you mean with...

How did you succeed in downgrading from 4.002.x to t.001.y ? Could you perhaps describe me that step by step? RS-232 card, nullmodem-cable, and software (terminal-emulator and tftp-server) i have already installed on my windows-pc. How to start now from here? Your help would be appreciated very...

In my case: I have configured the NVR5216-4ks2 that it records for a minute the mainstream under h.265 , VBR, maximum resolution and quality to its hdd (wd purple). Trigger to such record is a change (e.g. from nc to no) in the external alarm input at a registered12mp-dome. Later i found out...
