Government-Grade Video Conferencing Platform Built with WebRTC
The Problem
A government agency needed a secure, self-hosted video conferencing platform that met compliance requirements no commercial solution could guarantee. They required encrypted peer-to-peer meetings, the ability to embed live IP camera feeds directly into conference sessions for real-time surveillance monitoring, and a full observability stack for operational oversight. Off-the-shelf platforms like Zoom or Teams could not satisfy their data sovereignty requirements, could not integrate with existing IP camera infrastructure, and did not provide the deep system monitoring that mission-critical government operations demand. They needed a purpose-built platform where security, compliance, and observability were foundational — not optional add-ons.
Why Building a Government-Grade Video Conferencing Platform Is Hard
Secure video conferencing for government operations combines the real-time demands of media streaming with the compliance rigor of classified infrastructure and the operational visibility of mission-critical systems:
- End-to-end encryption with no third-party trust — government communications require encrypted peer-to-peer connections where media never traverses external servers. The platform must handle encryption, key exchange, and secure signaling entirely within controlled infrastructure
- IP camera integration into live conferences — embedding surveillance feeds requires bridging two fundamentally different video protocols (RTSP camera streams and WebRTC browser conferencing) in real time without introducing latency
- Compliance-ready data storage and retention — session recordings, metadata, and audit logs must be stored in a searchable, tamper-evident format that satisfies government regulatory requirements. Every session must be auditable
- Mission-critical reliability — government operations have no maintenance windows. The platform must maintain high availability with failover, health monitoring, and graceful degradation under load
- Deep observability across the entire stack — government platforms require real-time metrics (Prometheus), visual dashboards (Grafana), and searchable logs (Elasticsearch) for full visibility into every layer of the system
- Self-hosted, sovereign infrastructure — the entire platform must run on government-controlled infrastructure with no external dependencies, cloud vendor lock-in, or data leaving the security perimeter
What We Did
Architecture & Security Foundation
- Designed the self-hosted architecture with Node.js backend services, Angular frontend, and PostgreSQL for structured data — all deployable within government-controlled infrastructure
- Integrated Janus as the WebRTC media server — handling encrypted peer-to-peer conferencing, SFU for multi-party meetings, and RTSP-to-WebRTC bridging for IP camera feeds
- Established end-to-end encryption for all media streams and signaling channels, with no media traversing external infrastructure
Core Conferencing Platform
- Built the Angular frontend with a secure conferencing interface — meeting rooms, peer-to-peer calls, screen sharing, participant management, and administrative controls
- Developed the Node.js backend handling meeting scheduling, room provisioning, user authentication, role-based access controls, and session lifecycle management
- Implemented Jibri for server-side session recording — capturing meetings in compliance-ready formats with metadata tagging for searchable archival
IP Camera Integration & Surveillance
- Built the RTSP-to-WebRTC bridge using Janus — converting live IP camera streams into WebRTC-compatible feeds embeddable directly into active conference sessions
- Developed the camera management interface — administrators can add, configure, and assign IP camera feeds to specific meeting rooms or monitoring dashboards
- Implemented multi-stream layouts where participants view both peer video and surveillance feeds simultaneously within a single conference session
Observability & Compliance
- Deployed Prometheus for real-time metrics collection across all services — media server health, connection quality, resource utilization, and session metrics
- Built Grafana dashboards for operational visibility — active sessions, system health, resource utilization, and alerting for anomalous conditions
- Integrated Elasticsearch for searchable log aggregation — session audit trails, system events, and security logs indexed for rapid compliance queries and incident investigation
Key Results
In Their Words
Trembit delivered a conferencing platform that meets our security requirements without compromising usability. The IP camera integration and observability stack set it apart from anything commercially available.

What We Learned
Janus is the right foundation for government WebRTC — if you invest in the orchestration layer above it
Janus provides the low-level media handling: WebRTC endpoints, SFU routing, RTSP bridging, and plugin extensibility. But raw Janus is an engine, not a product. We built a complete orchestration layer on top — room management, participant tracking, stream routing decisions, recording triggers, and failover logic. Choosing the right media server saves months, but the production-grade platform is in the orchestration you build around it.
IP camera integration is a protocol bridging problem, not a feature request
RTSP camera streams and WebRTC browser sessions operate on fundamentally different protocols, codecs, and timing models. Bridging them in real time — with acceptable latency, synchronized audio, and stable connections — required dedicated engineering in the Janus RTSP plugin, transcoding pipeline, and stream health monitoring. We treated camera integration as its own subsystem with independent scaling and failure handling.
Observability in government platforms is infrastructure, not tooling
In commercial platforms monitoring is a nice-to-have. In government platforms, observability is a compliance requirement — every session auditable, every event logged, every metric retainable. We designed the Prometheus/Grafana/Elasticsearch stack as a first-class architectural layer with its own storage, retention policies, and access controls. The monitoring data received the same security scrutiny as the media server itself.
