Akuvox - R20B4 IP video door station - multi-user - 4 doorbells with RFID badge reader

Communicate with your visitors or open the door to them with your smartphone, from all over the world.

The connected video doorman allows you to see in real time who rings at the door of your home even if you are away. Connected to your internet box, it is installed instead of a traditional doorbell and allows a visual verification of the visitor's identity.

When a visitor rings the doorbell, you will receive on your console Akuvox , your smartphone or tablet, a push notification or a call notifying you of the presence of a person. You will be able to see who the visitor is in HD and wide-angle as well as talk to him. The doorman can of course be used at night thanks to his night vision.

The Akuvox doormen are SIP and ONVIF compatible. You will be able to recover the video stream on your SIP phones or secure your video recorder for example.

This model includes an RFID badge reader and an NFC reader to control the opening of an electric striker or lock from RFID cards or badges or from an NFC-enabled phone (Android).

The RFID badge reader or NFC reader is paired with one of the relays equipping this intercom. It can thus direct any type of electronic aperture by impulse. The relay is bidirectional and bistable.

Up to 5 call buttons

The R20B comes in different versions ranging from 2 to 5 buttons. Simply choose the version that corresponds to the number of families present in the building. Each button will call a different user.

Access your video doorman wherever you are

The IP connection allows you to stay connected 24/7 with the images transmitted by the video doorman.

The 1080p camera provides you with high-definition videos to see who arrives outside your front door directly from your smartphone (iOS or Android compatible) or from a tablet.

Built-in infrared LEDs provide quality night vision in any circumstance.

Interact remotely with the visitor

The two-way audio link allows you to interact live with the visitor.

The video doorman has several relays that you can activate remotely from your Smartphone, for example to open a garage door or an electric striker.

This doorman includes an RFID reader, it is possible to distribute badges or RFID cards between the different users authorized to access the site, whether it is a company or a private home.

The cards or badges can be configured from the web interface ofAkuvox in order to assign to each time slot and individual action plans.

For example, badge 1 allows access to the site from 6am to 8am and opens the portal. Badge 2 allows access to the site from 9am to 6pm and opens gate and door.

Compatible SIP

Doormen and Akuvox screens are truly SIP compatible. You will then be able to configure your Akuvox equipment to make SIP calls, for example by using your SIP account. Thanks to this, your doorman will be able to call a landline or a natel, for example.

Cloud access and subscription

Akuvox products can be used with or without a cloud. Access to the Akuvox cloud is through the SmartPlus smartphone app. For example, it will allow you to receive video calls, operate relays, generate temporary QR access codes, view visit history, trigger photo taking, etc.

If you purchase a video intercom and a screen from us at the same time, we offer you the cloud for life. Unlike the license you can purchase on our site, the version we offer does not include the possibility of making calls on fixed lines.

If you don't want a screen, you can choose to purchase a cloud license for a year or you can purchase a cloud license for life.

These licenses are valid for one residence/family, up to a total of 4 cloud users. Beyond 4 users, a subscription of 2 CHF per month will be required per additional user (for the 5th, 6th etc.).
