SENTINELLink • Locate • Communicate
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.
We build practical emergency tools that work before, during and after disruption. Sentinel OS 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.
