Door Phones Buying Guides and Features

Door Phones can be directly incorporated into Telebroad's PBX system, allowing for handling of guests and workers traffic into an office without need to invest in an additional system.

Please note that a compatible door latch need to be installed in order for the Door Phone to be able to open a door remotely. This is not done by Telebroad, but by a knowledgeable locksmith.

Extra requirements for installation


See our installation guide for more information on these.


ATA - A device that enable analog Door Phones to connect to regular IP network/phones.

SPA 112 - is a type of an ATA device made by cisco. 


SRC-1 - enables an analog phone to securely control a doorstrike or gate controller at a remote location. The SRC-1 contains a feature to eliminates the possibility of someone dialing the activation code through the entry phone using a hand held touch tone dialer.


POE Injector - a device that adds power to an Ethernet cable for consumption by gear operating on Power Over Ethernet (PoE) but is connected to a network equipment that is supporting of POE technology otherwise.   



Explanation of features and terms 


Door Phones comes with several distinctions:

  • Keypad - The most apparent distinction is if a model comes with a keypad or not. A keypad adds the functionality of a guest being able to dial different extensions in an office or workers able to dial a code in order to enter the office. A Door Phone without a keypad can only dial one extension, usually to a receptionist.

  • IP/Analog -  An IP Door Phone can directly interact with Telebroad's PBX system just like any VoIP phone. An analog Door Phone will require an additional hardware to convert analog signals to digital signals in order to achieve the same interaction. IP Door Phone is therefore more economical, but the choice really depends on the wiring that you have running to the physical location of the Door Phone.

    Another advantage of IP Door Phone is POE - Power Over Ethernet. A POE phone does not require connection to a power outlet to operate and instead receives power directly from the Ethernet data line. By nature an analog phone never offers POE.

    Analog Door Phones require a separate purchase and installation of remote controller unit, like Viking SCR1, to facilitates the remote opening of a door.

  • Indoor/Outdoor - The physical built of a Door Phone would determine if it is weather proof and tamper resistant or not and hence if it can be used outdoors on not. A Door Phone placed in an indoor environment (a corridor just outside an office), would not require any special protection from the weather.  A Door Phone that is placed in an outdoor environment does require some additional weather proofing, a rain cover and water resistant keys, as well as a tamper resistant materials and construction.

    Some models offer additional covers that can be attached to them to offer extra weather protection.

  • Camera - A camera enables a Door Phone to send a video image of the guest to the receptionist or other office personnel. However video signals either require additional cabling or an IP connection.
