How to use

Connect the DoorPhone 20-2W to the building’s 2-wire intercom line according to the installation instructions and ensure power is supplied. Configure household assignments and indoor station connections so each household receives separate calls. Install the companion mobile application on a smartphone, pair it with the DoorPhone unit using the app’s setup workflow, and grant required permissions for live video and notifications. Use the indoor station or mobile app to answer calls, view live video, and operate door release functions. Recorded video and snapshots are stored on the device’s internal memory and can be reviewed via the indoor station or through the app if the firmware and app support playback.

Usage recommendations

For reliable operation, install the external unit in a sheltered location protected from direct weather exposure, follow recommended 2-wire cable specifications, keep the companion app and device firmware updated, and configure user permissions separately for each household to maintain privacy. Regularly check available internal memory and back up important recordings if long-term retention is needed.
