An incident reported at a subterranean site with zero signal, still lands in seconds.
Zinc Systems builds the incident management and resilience platform trusted by security and facilities teams across some of the world's most complex buildings. XFactr engineered SYNAPSE Reporter and SYNAPSE Patrol Management, the mobile core that lets guards log incidents, run patrols, and trigger emergency alerts, online or off.

Built for guards who work where the network doesn't reach
Zinc Systems is UK-built and independently certified to ISO 27001 and Cyber Essentials, serving security and FM providers, real estate portfolios, and critical infrastructure operators. SYNAPSE needed to work in basements, plant rooms, and dead zones just as reliably as it works at street level. Here's how the engagement was structured, from first line of code to production rollout.
Embedded T&M Engineering
Mobile, backend, and QA engineers joined Zinc's delivery cadence, spanning our full stack development and quality engineering disciplines.
Full-Ownership Build
XFactr took end-to-end ownership of the SYNAPSE Reporter and Patrol Management apps, from native mobile through backend and cloud infrastructure.
Architecture Proof of Concept
Offline sync, battery-aware GPS, and low-latency SOS dispatch were each proven out before being hardened for enterprise scale.
Production Deployment
Live on Android and iOS today, backed by AWS cloud infrastructure built for enterprise-grade security.
Zinc Systems: risk, resilience and incident management, made operational
Zinc Systems is a British platform used by security and facilities teams at organizations spanning studios and entertainment, commercial real estate, retail, and critical infrastructure. The platform is G-Cloud approved, Crown Commercial Service listed, and built on AWS, the same enterprise-grade cloud foundation XFactr's engineering runs on for this engagement. This kind of high-trust, safety-critical software is exactly where our enterprise platform engineering earns its keep.
System architecture, end to end
SYNAPSE runs as a layered system: native mobile clients, an API gateway, a Node.js backend platform, spatial and object storage, and real-time dispatch. Every layer was built to keep working when the network doesn't.
Nine modules, one field-ready system
Each module was built to work independently and together, from sign-in to compliance reporting.
Authentication & Role Management
Secure sign-in on AWS with Enterprise SSO and role-based access control for strict data segregation.
Incident Reporting & Logging
Captures photos, video, audio notes, and GPS coordinates to log hazards, security breaches, and maintenance issues.
Patrol & Checkpoint Management
NFC tag scanning, QR verification, and GPS geofencing validate patrol routes and monitor guard tours in real time.
Task & Workflow Management
Automates task assignment, SOPs, safety checklists, and dynamic escalation flows.
Real-Time GPS & Geofencing
Tracks guard positions to optimize dispatch response and support lone-worker safety.
Panic & SOS Alerts
Immediate emergency triggers broadcast exact location coordinates to central control rooms for rapid dispatch.
Offline Operations Engine
Buffers incident submissions, checkpoint logs, and high-resolution media locally, syncing automatically once the network returns.
Analytics & Compliance Reporting
Generates compliance audits, incident pattern analytics, response-time metrics, and PDF/CSV exports.
Settings & Device Management
Configures location-tracking frequency, battery-saver profiles, notification thresholds, and offline sync parameters.
What made this genuinely difficult
Building for guards in basements, remote sites, and long shifts surfaces problems most consumer apps never face.
| CHALLENGE | DESCRIPTION | SOLUTION |
|---|---|---|
| Offline Synchronization | Field personnel operating in subterranean, remote, or poor network coverage areas. | Local Realm database caching with idempotent sync queues and background retry logic. |
| Battery Optimization | Continuous GPS tracking during extended shifts severely depletes battery life. | Motion-aware dynamic location intervals, balancing update frequency between stationary and active states. |
| Data Security & Integrity | Guard logs and incident reports must remain tamper-proof for legal compliance. | AES-256 local encryption, TLS in-transit protection, and cryptographic media hashing. |
| Low-Latency SOS | Critical emergency alerts demand immediate delivery to security control desks. | WebSocket integration backed by high-priority push notifications (FCM / APNs) with multi-channel fallback. |
| Resource Optimization | High-resolution image and video uploads exhaust cellular data quotas during shifts. | On-device media compression, adaptive transcoding, and throttled background queue execution. |
