SYSTEM VIEW

On the wrist for them. On the console for you.

Njord Sentinel is a safety awareness system for high-risk job sites. The system pairs our Indestructible Smartwatch™ with a live console for your team. On the wrist, workers get a tough, reliable tool for timekeeping, alerts and check-ins that fit into the way they already work.

When something happens, Sentinel surfaces it in in live notifications on the dashboard, giving supervisors timely alerts and clear context to act, escalate, and follow up.

A watch they'd choose anyway

The Indestructible Smartwatch™ handles the everyday basics workers rely on: durable casing, long battery life, easy-to-read display and essential apps. It’s designed to be worn continuously, in conditions that would destroy a normal smartwatch.

Live workforce overview

Sentinel provides a shared view of crews and conditions across sites. Leadership can see staffing levels, active alerts and trends at a glance, enabling faster, coordinated decisions rather than reactive, fragmented responses.

Data with clear limits

Sentinel ingests detailed on-shift signals from the watch and converts activity into risk scores, trends and simple flags at the worker, crew or site level. It does not record audio, intimate biometrics or off-shift activity.

Clarity after critical events

Sentinel provides an objective trail of operational activity around a critical event. It enables more rigorous analysis and follow-up, with the aim of improving procedures and protection for future shifts.

Operational use cases

Where Sentinel changes outcomes

Njord Sentinel is designed to be used in environments where human presence, exposure and response must be observable in real time. It changes outcomes by reducing uncertainty when something happens, and by surfacing early signals when something feels off.

Sentinel doesn’t replace judgment. It removes blind spots so judgment is based on what actually happened.

during operations

Immediate awareness of critical events

Fall detections, high-risk settings, and no-response situations surface as they happen, reducing delays in emergency cases

after an incident

Clear event context

Sensor data and time markers help reconstruct what happened without piecing together partial accounts.

over time

More informed decisions

Heart rate, blood oxygen, temperature, and elevation signals add context when work becomes physically demanding or conditions change.

hardware

The last smartwatch your team will ever need.

Adoption doesn't start with the dashboard. It starts with gear your team already trusts. Njord Gear smartwatches are being worn daily by workers in construction, industrial, and high-risk field environments.

Operational use cases

Designed for high-risk job sites

Construction

High-rise, large commercial, infrastructure, and complex construction sites where multiple crews work at elevation, under changing conditions, and across long shifts, where understanding exposure, presence, and instructions matters before and after incidents.

Apply for a pilot

Industrial Operations

Heavy industrial plants, manufacturing facilities, mines, and quarries where workers operate around machinery, confined spaces, and hazardous environments, often under demanding physical conditions over extended periods.

Apply for a pilot

Energy

Onshore and offshore oil and gas operations, including refineries, chemical plants, and tank farms, where environmental exposure, isolation, and strict operational accountability are critical to safety and compliance.

Apply for a pilot

Utilities & Grid

Utility and grid crews working at height, along lines, or in remote locations, often alone or in small teams, where situational awareness and lone-worker risk are a constant concern.

Apply for a pilot

Critical Infrastructure

Ports, rail yards, large logistics hubs, and infrastructure facilities where human activity intersects with heavy equipment, restricted zones, and time-sensitive operations that leave little room for guesswork.

Apply for a pilot

Public Safety & Emergency Response

Firefighting, disaster response, and urban search and rescue operations where teams operate in unpredictable, high-stress environments and need clarity around exposure, presence, and decision timelines.

Apply for a pilot

Defense & Defense-Adjacent Operations

High-risk ground operations where real-time awareness of personnel exposure and defensible post-operation records are essential, with strict boundaries around privacy and intent.

smartphone policies and safety

Phones down. Heads up.

Many organizations already restrict or discourage phone use because divided attention increases risk, particularly in physically demanding or hazardous environments.

Njord Sentinel supports a more controlled approach: a rugged smartwatch that provides essential communication and alerts without the distraction profile of a smartphone. Calls, notifications, and basic controls remain accessible, while the behaviors that lead to lost focus are structurally removed.

Sentinel is not designed to measure productivity. Any gains in focus or efficiency are a consequence of reduced distraction and clearer attention, not surveillance or performance tracking.
