2.800.0000013.0.R, Build Date: 2019-12-02

Guys - it's weird that cameras I've had for 4 years (untouched with no settings changes) are now malfunctioning with showing correct time when DST changes occur. See below screenshot for my settings but on blue iris which also hasn't been updated in years, the camera shows 1 hour behind since March 10. 5 other cameras (same model, firmware) and purchased from Andy at the same time don't have this issue. So far, I did a reboot, also clicked Sync PC that only helped temporarily

Thanks

Back in August it seems you had similar issues. At that time I asked you what was the device with the same IP as above, 10.6.6.168 and you replied it was "your firewall".

I would think that should be a NST time server name or the IP of your BI server running NetTime or similar.

Camera time

Guys - oddly enough, out of all 6 Dahua cameras purchased all from Andy, only one has only recently started giving me time zone issues. Super odd given nothing has changed and it's worked perfectly well for over 2 years. Same software running on all cameras too. Any troubleshooting I can do...

Ok but not sure why that would help. NTP does not handle time zones. All time data handled by the NTP protocol is in UTC

I take it then that you have NOT tried it.
I live in the U.S. as well, in Central Time Zone and it works great.:cool:
 
Can you give me the IP address of the NTP you use, I'll give it a shot. A few firewall rules I have to enable first but let me try

0.nettime.pool.ntp.org but it's 1 of 4 in a pool used by Nettime...which I urge you to try, it works very well.
 
Bigger problem now - the new NTP server doesn't stick. I tried hitting Save 5-10 times, did multiple reboots, just can't get it to stick and the old NTP server has stayed there. Maybe I have to do a software upgrade but know that it's best to erase all settings and set up as a new camera to do an upgrade and even with that, I could possibly brick it

Before you upgrade f/w, consider 3 factory resets as mentioned by @wittaj last year:

Can you give me a link to his post? I looked into his profile and various posts but can't find upgrade instructions anywhere

What browser?
 
So far so good. I had 2 problematic cameras
  • Camera 1- upgraded to latest version and connected to the same firewall NTP server and it's pulling time correctly
  • Camera 2 - did all the steps but forgot and confirmed it but realized at the end that I forgot to upgrade LOL. I kept it as-is to see if factory reset thrice simply fixes the issue but if it doesn't, I'll repost on this thread in 6 months so we have some real data
Btw using a firewall for NTP isn't considered unreliable. I just like to take out as many dependencies as possible such as a Windows app. I do have 5 cameras (both Dahua and Amcrest) that have been pulling time correctly for years from this firewall

Thanks
 
Update - factory reset didn't do it and I'm now upgrading Camera 2 that I forgot to last time. I have 3 other cameras and wondering if I should just get those done or wait if they develop the same issue. They were purchased at the same time from Andy. Curious why only some cameras develop this issue
