Setting the Time

You can set the time in Settings - System - Time and Date.

It can be set to an accurate time through time synchronization (NTP, RFTC, GPS, Windows).

Time synchronization with NTP

Time synchronization is possible through a time-synchronized NTP server. Time synchronization can be performed by setting the synchronization mode to NTP, entering the target IP, and pressing Synchronization When you automatically check time synchronization with the server, it receives and synchronizes time information from the NTP server at the specified time. (NVR supports NTP servers by default; time synchronization between NVRs is possible.)

GPS Time Synchronization

If GPS time synchronization is available, GPS is displayed as shown in the picture above and the reception rate is displayed on the right.

Select time synchronization mode as GPS and click Sync to synchronize time.

If GPS signal reception rates fall between high-rise buildings where GPS signals fall, weather effects, etc., they may not be synchronized.

System policy on time change

If time goes backward, that is, past the time of the current system, restart the program unconditionally. It does not restart if time goes forward, but in any case, if time changes, network connections and recordings are interrupted before time changes and restart after time changes.
