Niko Access Control - Digital - What to do if the external unit switches to night mode during the day?

The external unit will switch to night mode by itself based on the light intensity measured.
If the external unit has been placed in an environment where there is not much daylight, the image may switch to night mode during the day.

With software version 2.0 or higher, it is possible to switch over to Astro Clock mode using your smartphone or video indoor unit. The external unit will switch over to night mode at sunset and will switch back to day mode at sunrise.

The Astro clock can be adjusted to fit the ephemerides of your location.
