V2000 do not keep time after reboot when sync to pc or manual time setup
The V2000x series do not keep time on a power cycle. They revert back to 1-1-1970 when power is cycled.
The V2100 series cameras do keep the time on a power cycle.
The Synchronize with PC is a onetime event. Even manually setting the time is reset to 1-1-1970 when power is cycled
Valerus doesn’t need the time synchronized to record.
Valerus also has an NTP server included. You can sync the camera to Valerus NTP.
You would need to set the time in the camera in the following conditions-
- Using the event scheduler in the camera.
- Recording to SD card. The camera needs the correct time/date for the filename on the SD card.
- Creating a self-signed certificate. Time must be synced before certificate is created.
- Using the OSD to display the time/date.
