Compact four button audio intercom panel

Akuvox R20BX4 is a compact SIP video doorbell with four separate call buttons with name plates.

Thanks to its small size, it fits particularly well in locations with limited installation space.

The device is designed for outdoor use and is easy to install. Suitable for use in single-family homes, semi-detached houses, apartment buildings and villas.

The device has a wide-angle camera (110° horizontal, 58° vertical), which provides good visual overview of the entrance area.

Supports two-way IP-based audio connection with echo cancellation function.

Power supply via PoE (IEEE 802.3af), which reduces wiring requirements.

Compatible with SIP and ONVIF standards, enabling connection to various network-based video surveillance systems.

Works with indoor monitor and/or Akuvox mobile application.

Thanks to SIP technology, the indoor unit (monitor or phone handset) can be completely omitted — the call panel calls directly to the user’s phone.

No app is needed for this. You only need to enter into a VoIP service contract with your telecom operator.

Akuvox R20B helps increase building security by allowing you to control who enters and identify visitors both visually and verbally.

The R20B series includes various models with up to five call buttons with name plates in total – this allows one device to serve multiple apartments or users.
