pinkoos Posted March 19, 2019 Share Posted March 19, 2019 Lilin cameras connected to a Zuum NVR The timestamp coming from the NVR is correct However, the timestamp (which is stamped on the camera feeds) is not correct We've gone into each cam's configuration page and tried both the options of syncing the time with PC and syncing the time with an NTP server Works for a few hours and then the time messes up again (off by 5 to 6 hours usually) We're at a loss of what is going on This all started after DST here in the US Quote Link to comment Share on other sites More sharing options...
Matt Lowe Posted March 19, 2019 Share Posted March 19, 2019 might try a new dns server like 8.8.8.8 also if they will let you change ntp server might try a new one there too Quote Link to comment Share on other sites More sharing options...
Pounce Posted March 19, 2019 Share Posted March 19, 2019 Go to advanced/system/timer and set the timezone and daylight savings time settings. Ensure you have a good ntp timeserver and that the cameras can reach it. Be sure to tick the radio button for sync every hour. Quote Link to comment Share on other sites More sharing options...

I changed the NTP server from time.nist.gov to us.pool.ntp.org - it worked for maybe half a day or so and then the time messed up again For example, it's 6:34 AM right now, but the cams are showing 11:34 AM Really frustrating issue as we finally got cams that work with our touchscreens, Navigator and NVR but now this problem has cropped up The timestamps are important since if we ever need to use footage for any kind of proof of something happening, having the wrong time printed directly on the video will undermine anything we're trying to prove Quote Link to comment Share on other sites More sharing options...

If you have a bandit assault you and smiles nice for the camera I think the judge is going to maybe be understanding of your timestamp issue on your residential cameras. You are actually better off not having the timestamp. The NVR is probably properly marking the time on the track. 7 hours ago, pinkoos said: Where do I change the DNS server? I'm guessing you probably have access to the manual and the google. Basic>network>general Quote Link to comment Share on other sites More sharing options...

pinkoos Posted April 5, 2019 Author Share Posted April 5, 2019 I updated the firmware for all 4 cams, reboot them and reset the timestamps, but the problem is still there All 4 of them seem to add about 5 to 6 hours around the same time of day, between noon and 2 PM For example, I checked them about 45 mins ago or so (maybe 1:15 PM local time) and they were fine Just checked again (around 2 PM local time) and they all say it's about 7 PM local time Quote Link to comment Share on other sites More sharing options...

pinkoos Posted April 5, 2019 Author Share Posted April 5, 2019 There are two options for my time zone in the cam settings: Central standard and another one that lists a few cities, including Houston. Both of those are -600 GMT (or something like that) And I've checked off Daylight Savings time as well Regardless, I've switched back and forth between the two choices, had DST checked on and off, tried turning off NTP server sync and just syncing to PC, but nothing sticks for more than 12 to 18 hours It's crazy Quote Link to comment Share on other sites More sharing options...
Cyknight Posted April 5, 2019 Share Posted April 5, 2019 MAybe set the camera drivers in C4 to sync time with C4? I think Lilin cams have that option.... Quote Link to comment Share on other sites More sharing options...
pinkoos Posted April 5, 2019 Author Share Posted April 5, 2019 I'll see if my dealer can check if that's available and if he can do that, thanks Quote Link to comment Share on other sites More sharing options...
pinkoos Posted April 9, 2019 Author Share Posted April 9, 2019 After much research and googling online the last week or two I came across a single post on an IP cam forum that mentioned a similar problem and the following potential solution: In the NVR’s System->General settings pane, there is an option to check or uncheck “IPC Time Sync” It had been checked all this time, so I unchecked it very early yesterday morning and, so far, the cams’ timestamps have not messed up. They usually mess up sometime between noon and 2 PM, so the fact that they haven’t messed up since I changed the setting early yesterday morning is a good sign.
