How to Use NTP to Synchronize Time

The NTP (Network Time Protocol) is a network protocol for clock synchronization. You may use the NTP to synchronize the time. Check more detailed information below.

Applies to: All Reolink devices except battery-powered cameras.

Note: Reolink battery-powered cameras do not have the NTP feature as these cameras will synchronize date and time automatically once it is connected to the internet.

Since the NTP use the UDP port 123 by default, you may use it to verify whether the UDP port is enabled or not according to the synchronization result.

Via Reolink Client

Step 1. Log in to the device and go to Device > System > Date & Time > Synchronize. If you get a prompt Succeeded, then it synchronizes successfully.

If you want to set up NTP, you can go to Network > Advanced > NTP Setting. Configure the NTP settings as what you need, then click on Save to save the settings.
