A video door phone, also known as a video intercom or video doorbell, is a security system that allows homeowners or business owners to see and communicate with visitors at the door before granting access. Here's a quick breakdown:
How it Works
Outdoor Unit (Door Station):
Equipped with a camera, microphone, speaker, and sometimes a call button.
Installed near the entrance or gate.
Some models include night vision and motion detection.
Indoor Unit (Monitor Station):
Features a display screen to view live video from the outdoor unit.
Has controls for two-way audio communication, door unlocking, and sometimes recording.
Can be wall-mounted or portable (tablet-style).
Door Unlocking Mechanism (Optional):
Integrated with an electric strike or smart lock.
Allows you to unlock the door remotely via the indoor unit or a smartphone app.
