5. When there is a time difference between the NVR and the NTP server
| Time Difference | Sync | Remarks |
| 0-1 second | No Syncing | NTP synchronization does not work. |
| 1-5 seconds | Syncing | The RTC and system time are changed to the NTP server time. |
| After a system pause occurs, the RTC and system time are changed to the NTP server time (overlapping intervals occur) | ||
| 5 seconds to 60 minutes | ||
| 60 minutes or more | No Syncing |
