Why Do You Need a Smart Intercom?
Access control systems are usually paired with an intercom function, allowing two-way communication between visitors and residents (or managers).
Modern systems go further by integrating a camera, letting users perform a complete security check with video and audio before opening the door.
Pain Points of Traditional Intercom Systems

Requires Being On-Site
Managers must physically go to the device to respond, which is both inconvenient and reduces work efficiency.

Complicated Installation
Most intercom systems require extensive wiring and can even damage the building structure, making new construction or upgrades difficult.

Limited Access Control Integration
Traditional intercoms are often limited when combined with access control, with poor extensibility and management efficiency.

Insufficient Security
Lacking features such as geofencing and video verification, making it hard to effectively ensure security.
