Intercom

A video door phone intercom is a communication system that combines the functionality of a doorbell, intercom, and video camera. It allows for two-way communication and visual identification between a visitor at the door and the occupant inside the building. The system typically includes an outdoor unit with a camera and microphone at the door, and an indoor unit with a display screen and speaker for the occupant to see and communicate with the visitor. Video door phone intercoms enhance security by enabling remote monitoring and control of access to residential and commercial premises.
