Intercoms continue to provide secure, localized communication across hospitals, airports and residential buildings. Today's systems are typically IP-based with video, mobile app support, PoE installation and stronger encryption. They improve visitor screening, emergency coordination and operational convenience. When selecting a system, prioritize network compatibility, vendor update practices and accessibility features, and plan for ongoing maintenance.

Why intercoms still matter

Intercoms remain a core part of building communication and security. Once limited to audio-only desk units, modern systems add video, network connectivity, mobile apps and integrations with access control. That evolution keeps intercoms useful in hospitals, airports, multifamily housing and many other settings.

Common use cases

Hospitals and airports

Facilities use intercoms for quick, localized communication between departments, secure entry points and emergency paging. Intercoms sit alongside mass-notification systems to speed triage and coordinate staff during incidents.

Apartments and multifamily buildings

Residents use door-entry intercoms to screen visitors without leaving their unit. Video-capable units and mobile apps let residents see and speak with visitors, then unlock doors remotely when appropriate.

What has changed: technology highlights

Modern intercoms are largely IP-based and integrate with building networks. That enables features such as app-based calling, cloud device management and SIP-compatible telephony connections.

Most new systems support video with higher-resolution cameras and wide-angle lenses. Power over Ethernet (PoE) simplifies installation by carrying power and data on a single cable.

Security and privacy have also advanced. Systems commonly use encrypted connections and support firmware updates from vendors to address vulnerabilities. Many intercoms integrate with access control, elevator recall and CCTV so a single event (for example, an authorized entry) can trigger related systems.

Benefits in practice

Intercoms improve convenience and safety. In residential settings they reduce unnecessary contact and give residents control over who enters the building. In institutional settings they speed coordination, support localized emergency announcements and can provide an audit trail of access events.

Video-capable intercoms reduce uncertainty about a visitor's identity. Mobile integration means staff or residents can respond even when they are away from the building.

Buying and deployment considerations

When choosing a system, prioritize compatibility with your existing network and access-control infrastructure. Check for PoE support to lower wiring costs. Evaluate how the vendor handles software updates and data protection.

Also consider accessibility features - large buttons, visual alerts and compatibility with hearing-impaired support tools - so the system serves all users.

Maintenance and lifecycle

Treat an intercom system as ongoing infrastructure. Plan for regular firmware updates, physical cleaning of camera lenses and periodic review of access logs. Working with a qualified installer or building-systems integrator helps ensure the system stays secure and reliable over time.

FAQs about Intercom Phones

What's the difference between legacy and modern intercom systems?
Legacy systems were analog and audio-only. Modern intercoms are usually IP-based, offer video, integrate with mobile apps and building access control, and use encrypted network connections.
Can I answer an intercom from my smartphone?
Yes. Many IP intercoms support mobile apps or cloud services that route calls to smartphones, allowing users to see visitors and unlock doors remotely.
Are video intercoms more secure than audio-only systems?
Video adds identity verification, which reduces uncertainty, but security depends on proper configuration, encrypted communications, timely firmware updates and strong access controls.
Do intercoms help during emergencies?
Yes. Intercoms provide localized alerts, enable quick coordination among staff and can integrate with wider emergency-notification systems to speed responses.
What should I check before buying an intercom system?
Verify network compatibility (SIP/IP), PoE support, vendor update policies, integration with existing access control, and accessibility features for all users.
