Audio vs Video Intercom: What Is the Difference?
The right choice is not only about adding a screen. Entrance count, door lock, existing cabling, mobile access and the way the site is used all affect whether audio or video is the better fit.
Core difference
What changes between the two systems?
Both let you communicate with a visitor, but the verification level and available features can differ.
Video intercom
Adds a live visitor view and helps you confirm who is at the entrance before opening the door.
Door release
Both can support door release when the lock, controller and power arrangement are compatible.
When to choose each
Match the system to the real workflow
There is no single intercom type that fits every project.
Choose audio when
- Voice communication is the main requirement.
- The site has a simple entrance setup.
- You do not need a live visitor view.
- You do not need video-related features.
Choose video when
- You want to see the visitor before opening the door.
- The site needs multiple monitors or entrances.
- You want mobile integration on supported systems.
- Stronger visitor verification is important.

Yes when the intercom, lock or controller and power requirements are compatible.
Can a video intercom connect to a mobile phone?
Some systems support app calls, notifications or remote door release when the required network and account features are available.
Can existing intercom cabling be reused?
Sometimes. It depends on cable type, condition and the architecture of the new system.
