Hi Guys,

2 of my 8 Dahua cameras keep defaulting back to H265 where I need H.264 to be compatible with the Home Assistant plugin WebRTC. I don't remember having this problem with other video parameters in the past. Assuming this isn't a firmware bug specific to a model is there something I'm missing that needs to be done other than selecting the save option after changing back to H.264? I can't find any option to copy the current configuration to the power up defaults. Any assistance would be appreciated.
 
Try setting it in Internet Explorer. Not Edge, not chrome with the IE add-on, but plain ole Explorer baked into Win10.

Some of these cams are that dependent on the right browser for the settings to hold.

I have this problem with 6 pcs Dahua EZIP cameras from 8, all are the same model and firmware.
I think I fixed once few camera by reset to factory default, now I don't have the time to reset them all so at this point I am using secondary stream H264 for HA.
 
@wittaj,
I was doing this on a Ubuntu box with Google Chrome. I took your advise and switched to a Win 10 box with IE and same problem, H.264 didn't "stick".

@MyDaHua,
I will try resetting to default and recovering from there when I get a change. As you mentioned very time consuming.
 
I verified I was using IE on my Win 10 box. I changed back to 264 hit Save 3 times then Refresh. It stuck at 264. After reboot it switched back to 265.

Ugh, that sounds like something wonky in the FW. Hopefully a factory reset fixes it.

Which model is it and we will see if anyone else has the same problem?

SD49225T-HN with 2.622.0000000.7.R.R4.2510.9A.NR, Build Date: 2018-04-04

IPC-HDW4231EM-ASE with 2.640.0000002.0.R, Build Date: 2018-05-23

I won't be in the position until next year with shot-gunning this problem with possible later firmware versions. I'll just turn off my weekly camera reboots and fix after any power outages.

I have had luck using Pale Moon 32 bit on Win10, and Brave (based on Chrome) on Linux Mint. The Brave on Linux works on almost everything, except for setting and reading one bit of data from a Dahua SD49225XA-HNR. As @wittaj says, IE under Win10 works every time, or almost every time - seems like rarely I have something that I have to try twice, but then it works.

Well I started this thread now 7 years ago. I don't remember the details but I can write where I'm at now.

I just checked the 2 cam's I listed above (The 2 that were defaulting to H.265). One is set to H.264 while the other is set to H.264H. Several years ago I switched to Brave Browser on Linux. It allows me to change every setting but some of my cams don't display live video where the Adobe plugin is required. It's fine for me since I have monitor right next to Brave showing me Live video output from my NVR. My best guess was that Brave on Linux solved this problem. I'm not a Windoze user so I can't help there. There may be other solutions.
 
While taking the time to document my camera network, I realized I had a Dahua NVR I bought for testing and it's just been sitting on my network.

Just posting my fix incease someone else has a similar issue.
