About day length time profiles
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 servers 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.
Create a day length time profile
1. Expand the Rules and Events folder > Time Profiles.
2. In the Time Profiles list, right-click Time Profiles, and select Add Day Length Time Profile.
3. In the Day Length Time Profile window, fill in the needed information. To deal with transition
periods between lightness and darkness, you can offset activation and deactivation of the
profile. The time and the name of months are shown in the language used your computer's
language/regional settings.
4. To see the location of the entered GPS coordinates in a map, click Show Position in
Browser. This opens a browser where you can see the location.
5. Click OK.
