    What do the specifications included in the door phone mean?

    Card reader

    The card reader will allow a user to unlock the door or gate by using a keyfob or access control card.

    SIP Protocol

    The SIP protocol is a well-known protocol to transport audio and video streams over a network or Internet between different devices or applications.

    Video door phone

    The video door phone is a device to identify somebody willing to enter a property, like an apartment building.

    Power over Ethernet / PoE

    Some routers, switches, or stand-alone devices can deliver electricity over the network cable. That avoids the necessity to run electrical wiring and brings money and time savings.

    How can you live without a LED display keypad SIP Video Door phone?

    How do you secure your apartment building?

    You aren’t always available. You could be working, doing groceries, sleeping, having fun, relaxing, or anything else. You would need a concierge to identify and evaluate every single person willing to enter your building. That could prevent burglars, muggers, door-to-door salesmen, or any other unsolicited person.

    How do you get to know who is really in front of the door?

    Sometimes you just don’t want to wake up, get out of your place, or just meet anyone. But how do you avoid unsolicited persons if you don’t go and see them by yourself?
    How to answer someone ringing at your door if you are out for groceries or at work?
    With a traditional intercom, it is difficult to know who is speaking effectively. Is he a real UPS delivery man? It would be nice to see you.

    What happens when you forget your keys? Or if you invited someone but you’re not available?

    You or your guests get stuck outside, waiting for somebody to open the door. You can also bother different neighbors to help you and open the door.

    What are the options of analog door phones?

    Do you remember how life was before smartphones? A mix of mechanics and electrical interaction to be able to communicate with a single person on the other side. Today installed door phones are still the same technologies for decades, making them difficult or impossible to connect to smartphones, computers, or the cloud.

    Why do you need a LED display keypad SIP Video Door phone R20A?

    The card reader will identify the user and open the door in a microsecond

    With a key fob, an RFID access control card, or even a Smartphone with NFC, you can identify any registered occupant of the building. The system will then automatically unlock the strike of the door to let the user come in.

    Connected to the Cloud, the R20A door phone makes it easy to manage and communicate

    Thanks to the SIP protocol and the computer-style technology, this door intercom can communicate on a computer network and enjoy all the digital options. The Cloud centralizes all the different door phones and door stations in one place so the manager can monitor, set up, and operate from anywhere.

    Have a video call with your guests

    What seems like a standard and simple feature is still quite new to the intercom market. However, a video call is much more convenient for identifying your guests and for sharing any visual communication than a simple audio call. Depending on your station, the guests could see you too or not. And thanks to computer technology, as new individual video doorbells, you will be able to perform this live video call from anywhere, as far as you are connected on the Internet.
