To maintain image clarity when the red and blue alarm lights are activated, the eufyCam S4 is designed to automatically switch from color night vision to black-and-white mode. This is because continued use of color night vision under active red and blue lighting can result in significant image degradation, including loss of detail and reduced visibility. The black-and-white mode ensures optimal contrast and preserves critical visual information during alarm light operation.

If you have any other questions regarding the eufyCam S4, please don't hesitate to contact us for assistance.
