Since the invention of the door intercom system, Siedle has focused on achieving continuous improvement. We have been working towards this goal for over 70 years with passion, commitment and the quest for perfection which is reflected in each and every one of our products.
Hearing, speech, door release – the classical intercom system forms the basis of all door communication. At Siedle, this basis offers a starting point for expansion and upgrading. Four design lines and countless style variants address every conceivable requirement and personal preference.
