Eliminate expensive, outdated wall intercom monitors!
I build cutting-edge Mobile Intercom and Smart Doorphone Systems that ring residents directly on their iOS and Android smartphones with ultra-low latency live video whenever a visitor arrives.
Key Capabilities:
- Instant Live Video Calls (WebRTC & SIP): Zero noticeable delay video and crystal-clear duplex audio over cellular and Wi-Fi.
- One-Tap Remote Door & Gate Unlock: Securely release electromagnetic strikes or motorized gates straight from the call screen.
- Native Call Experience (VoIP Push): Rings like a regular incoming phone call via iOS CallKit and Android ConnectionService.
- Security & Concierge Bridge: Internal calling between residents and security guards/receptionist consoles.
- Missed Visitor Snapshot Vault: Cloud storage for visitor photos and timestamps taken upon ring events.
- Hardware Agnostic: Integrates with standard SIP outdoor stations (Akuvox, Dahua, Hikvision) and smart IoT relays (Shelly, ESP32).
Tech Stack:
- Client App: Flutter (iOS & Android) with CallKit & WebRTC
- Media Engine: Janus Gateway / Asterisk / mediasoup
- Push: Apple Push Notification service (VoIP APNs), Google Firebase (FCM)
