What distinguishes the transponder module?


Integration in letterbox and co.

Thanks to the 2-wire bus technology, the integration of the Busch-Welcome® solutions is also possible in letterboxes, bell panels or door side panels. The basic audio module with microphone and loudspeaker can thus be easily combined with an additional camera and offers you the option of button expansion up to 99 buttons.

Make your door communication complete: outdoor stations

The transponder module can be integrated into the outdoor stations of the Busch-Welcome® system. With our modular outdoor stations, you can assemble your outdoor station individually and according to your needs.
