Please check the following depending on your connection environment:
・If cameras are connected via a recorder:
Ensure that the time zone and daylight saving time settings on the recorder are correct.
Then, try syncing the time with the NTP server using the steps below:

   1. Turn off [Time adjustment] in the [NTP setup] section on the [NTP/SNMP] screen, and save the change.
   2. Turn it back on and save again.

・If cameras are connected directly:
Ensure that the time zone and daylight saving time settings on the camera are correct.
Follow these steps to configure the NTP settings:

   1. Open the [NTP] settings screen under [Network] → [Advanced] on the camera.
   2. Select [Synchronization with NTP server].
   3. Enter the [NTP server address].
   4. Click [Save] to apply the settings.

If the issue persists after completing the steps above, please also check the time zone and time settings of the PC displaying the browser, or the mobile device running the i-PRO Mobile App.

If the issue is not resolved after checking the time zone and performing time synchronization using [NTP Setup], please check whether Network > Basic > DNS Setup on the recorder is set to On.
Also verify that the DNS server address specified by the network administrator is configured correctly. If no DNS server is specified, use the DNS settings of the router (default gateway).

If the issue still persists, as a troubleshooting step to determine whether the DNS configuration is the cause, you may set a public DNS server such as 8.8.8.8 and check the operation, provided that you have permission from the network administrator.
