SENTINELLink • Locate • Communicate
Sentinel began as Project Sentinel, an initiative focused on communications, preparedness and resilience technology. Our goal is to build practical tools that help individuals, families and communities remain connected, informed and prepared during emergencies and infrastructure failures.
Sentinel is building an off-grid preparedness ecosystem for preppers, families, rural communities, events and disaster response. Our nodes, app and future network tools are designed to help people plan, communicate, locate resources and stay safer in emergency situations.
Communications and networking hardware.
Preparedness, planning and emergency response platform.
Additional resilience and communication tools.
We build practical emergency tools that work before, during and after disruption. Sentinel app helps people organise supplies, documents, contacts, plans, medical notes, maps and radio logs. Sentinel Nodes are designed as portable communications hubs for off-grid messaging, local networks and field coordination.
A rugged portable communications system built to work alongside Sentinel app. Designed for local resilience, off-grid groups, field teams, events, farms, rural locations and preparedness communities.
Designed around resilient local communication and expandable node networks.
Built for GPS logging, rally points, maps and field coordination.
Focused on local control, private networks and preparedness workflows.
Portable, battery-powered and designed for real-world disruption.
