The new keyless Digicode keypad integrates a revolutionary technology based on sound analysis. Very small sensors placed on almost any type of material can identify the location of a sound and translates it into a digital key press, no longer using mechanical keys. This innovative technology and high-tech design create opportunities for use in special environments, such as architectural sites, or prestigious buildings and environments. Despite its design and technology features, the keyless Digicode still offers a high level of security for the user.
