I mentioned in a previous post that I was seeing some peculiar DNS issues/errors with a bunch of my Dahua cameras. This happens when I login to the problematic cameras. After entering my login credentials, there is a pause followed by a small "DNS Error" popup window. I can still get into the configuration screens, but I cannot see the camera image while I'm in there... it makes it impossible to configure things like motion detection zones and overlays.
I did some detailed analysis of all 17 cameras on the network and it appears to be happening with just two particular models (affecting 8 total cameras in my network). Furthermore, it seems likely the problem is due to a firmware issue.
Here are the Dahua camera models involved:
MODEL: HNC5241EN-IR-28
FIRMWARE: 2.400.0000.10.R, build : 2015-06-18
------------------------------
MODEL: HDBW4421E
FIRMWARE: 2.400.0000.7.T, build : 2015-12-09
-------------------------------
I have 3 additional HDBW4421E cameras with newer firmware that are working fine - no DNS problems
2.400.0000.28.T, Build Date: 2016-04-13
Can anyone point me in the direction of where I can find Dahua firmware updates in general, or for these cameras, in particular? I played Amazon roulette and the seller is no longer reachable. I really like these cameras, with the exception of the buggy ones I am dealing with.
Many thanks in advance for your advice!
