Video vs Audio Intercom: Which to Choose | Queen

Intercoms come in audio and video types. Here is how they differ so you can choose the right one.

Audio intercom

Simple and reliable voice communication, ideal for small homes and offices at a lower cost.

• Lower cost
• Easy to use
• Voice-only communication

Video intercom

Lets you see visitors before opening the door for higher security, and smart models add mobile control.

• See visitors before opening
• Higher security
• Smart models with mobile control

Video or audio intercom: which do you actually need?

Audio intercom is cheaper and adequate where the entrance is already covered by a camera or watched by a doorman. Video lets you see the visitor before opening — and that matters far more for villas, ground-floor apartments, and any door opening straight onto the street. For families with children home alone, video is not a luxury.

The wiring decides more than the choice

In an occupied building, whether you can add video often depends on the existing risers, not the budget. A two-wire system carries power, audio, video and the lock signal on a single pair, which is frequently the only realistic way to add video without pulling new cable through apartments. Ask what is in the riser before deciding.

The recurring fault

"The intercom works but the door won't open" is almost always the lock circuit, not the intercom. Give the lock a dedicated power supply and correct cable gauge and this call does not come back.

The main types, and where each fits

Choosing intercom systems starts with knowing the types rather than the brands — each was designed for a different situation, and matching the type to the situation matters more than the price:

• Audio: cheapest, enough where a camera already covers the door.
• Video: see the visitor before opening — key for villas and ground-floor flats.
• Two-wire: power, audio, video and lock on one pair — the retrofit answer for occupied buildings.
• IP: runs on the network, forwards to a mobile app, scales to hundreds of units.

Below the type, the details decide the result: component quality, correct positioning, and adequate supporting infrastructure. A mid-range choice installed correctly beats a premium one installed poorly.

Before you decide

Ask for a survey before a price — a number given over the phone is a guess that changes on site. For this system in particular, ask what is already in the riser before anything else, and insist the lock gets its own power supply — the "door won't open" fault is always the power, never the intercom. And ask what happens the day something fails: who responds, how fast, and whether the handover left you the documentation to let anyone service the system.
