The DoorBird D21DKH is a multi-tenant IP Video Intercom system designed for use in apartment buildings and multi-dwelling units. Installed at a front entrance or gate, visitors will be able to use the name directory to find and call residents.
Â
Residents will use the free DoorBird iOs or Android apps so they can see who’s at the entrance, listen in and have a two-way voice conversation. When connected to an electric strike or gate operator, the gate or door can be opened remotely by the resident.
Â
DoorBird features high-quality 720p video and full duplex two-way audio. The system provides full-color video during the day. At night, it will automatically switch to night mode which allows it to see in pitch black with its built-in infrared LEDs.
Â
The built-in RFID reader can be used with DoorBird cards or tokens to allow residents to automatically open a door or gate when they present their credentials.
Â
The D21DKH can also be used with SIP systems, has an open API, and can integrate with Control4, Crestron, RTI, URC, and many more.
Â
Please note: The Doorbird station no longer comes with a flush mount back box or a surface mount back box. These must be purchased separately and are needed for installation.
