The cleanly designed metal Qbus door entry units
can be linked to the Navigator displays or other
receivers that support the SIP protocol.

Qbus door entry units are vandal-resistant
and waterproof (IP65) and use the SIP protocol.
They can be integrated with the Qbus Navigator
displays or with other SIP receivers such as
Gigaset, Polycom or Grandstream receivers.
An app to enable viewing door entry unit images on
a smartphone will be available in the near future
