The holistic concept of the Busch-Welcome door communication system offers convincing solutions for numerous application areas and specifications. Individual details and differences in shape make this design unique, but its design vocabulary is reduced to the essentials and dispenses with the unnecessary. The high-quality colour camera of the Busch-Welcome video outdoor station has a particularly wide diagonal viewing field of 104 degrees. It switches over to day and night mode automatically. Infrared LEDs provide additional illumination for the visual range, to ensure that visitors are recognised also in the dark.
