NVR configuration : Configuring schedules : Setting the sunrise and sunset time
 
Setting the sunrise and sunset time
When specifying schedules, you can use specific day and time, or the sunrise and sunset time.
To get the sunrise and sunset time
1. Go to Schedule > Schedule > Settings.
2. Enter the latitude and longitude values of the FortiRecorder and camera location.
3. Click Calculate to retrieve the sunrise and sunset time. A few days’ sunrise and sunset time will be displayed.
 
When using a combination of sunrise/sunset and the specific time, if the time cross the boundary of sunrise/sunset, the schedule has no effect. For example, if the sunrise is at 8:00AM and you set the schedule from sunrise to 7:00AM, the schedule has no effect.
