When you place cameras outside, you must often lower the camera resolution, enable black/white or change other settings when it gets dark or when it gets light. The further north or south from the equator the cameras are placed, the more the sunrise and sunset time varies during the year. This makes it impossible to use normal fixed time profiles to adjusts camera settings according to light conditions.
In such situations, you can create day length time profiles instead to define the sunrise and sunset in a specified geographical area. Via GPS coordinates, the system calculates the sunrise and sunset time, even incorporating daylight saving time on a daily basis. As a result, the time profile automatically follows the yearly changes in sunrise/sunset in the selected area, ensuring the profile to be active only when needed. All times and dates are based on the management server's time and date settings. You can also set a positive or negative offset (in minutes) for the start (sunrise) and end time (sunset). The offset for the start and the end time can be identical or different.
You can use day length profiles both when you create rules and roles.
