The main features of ドアホン include the ability to answer visitor calls through your smartphone, monitor the entrance and sensor camera with video and sound, receive notifications from devices connected to the TV door system, and control devices like electric locks and air conditioners from your smartphone.

It is important to note that this app cannot be used with standalone TV door systems or smartphones that are not compatible. Additionally, the smartphone must be connected to your home Wi-Fi for the app to function. To answer visitor calls, the app must be launched beforehand.
