How video intercom systems work, the features that actually matter, and how to choose the right one in 2026.
Video intercom has become the default choice over audio-only for most new installations, since seeing a visitor before responding is a meaningful security improvement for very little added cost. But not all video intercoms are the same — resolution, field of view, and how the video is delivered (wired panel vs. mobile app) vary significantly between systems.

Quick answer: A visitor presses a call button on an entry station with a built-in camera; the resident or staff member sees live video and audio on a wall panel or phone app before deciding to let them in.
The entry station houses a camera, microphone, speaker and call button (or directory, for multi-tenant systems). When triggered, it connects to an answering device — either a dedicated wall-mounted monitor or a smartphone app — over wiring or the property's network.
Quick answer: A mobile app lets you answer and release the door from anywhere; a wall panel is simpler and doesn't depend on a smartphone or internet connection.
Mobile app answering is increasingly the preferred option, especially for households or businesses where someone isn't always near a fixed panel. That said, a wall panel remains a solid, dependable option and some properties use both — a panel as the primary answering point, with app access as a backup when away.
Residential systems are usually a single entry station paired with an in-home panel or app, sometimes tied to a gate.
Commercial entrances often pair a video intercom with access control for visitor screening at a staffed or unstaffed lobby.
Multifamily buildings need a directory-based system supporting many units — see our apartment and multifamily intercom guide for how this works at scale.
