The Challenge

Design a system that allows tenants to communicate with guests at the building entrance using live video and audio, while also managing gate access and verifying identities with facial recognition. The solution had to work across different devices and platforms, including dedicated intercom hardware and mobile phones, while ensuring reliability, low latency, and privacy.

The Solution

We developed a cross-platform communication system powered by WebRTC, enabling real-time video and audio between tenants and guests. The solution includes a React Native mobile app for residents, an intercom app installed on Android-based devices at building entrances, and a Node.js backend managing signaling, authentication, and access logic.

Facial recognition was integrated to allow residents to receive visual identification of guests before opening the gate. The system architecture supports dynamic call routing, permission-based access control, and fallback mechanisms to ensure reliability. Everything was designed to work with minimal setup, secure connections, and a responsive user interface that feels immediate and intuitive.
