Setting up the correct time is often needed if there has been a time change or settings have not been added for daylight savings.
To change the camera system time, right click anywhere on the main camera screen, and select System, then click Time, and finally select time once again.
Proceed to select the correct time zone, and change the time and date format to your preference.
Time Synchronization: Use this function to synchronize camera time with the NVR. Time sync is enabled by default, and cameras will synchronize time with the NVR after getting online, and then synchronize once every 30 minutes. To enable this, click System > Time > Time Sync.
