The Intelligence Behind Connected Worker Safety

The Swanholm Sense Collar is the core intelligence of Swanholm Technology’s Connected Safety Ecosystem. Designed to help protect workers in demanding environments, the collar combines Edge AI fall detection, emergency alert workflows, Bluetooth connectivity, and app-based safety management in a single wearable platform.

Unlike traditional safety garments, the Swanholm Sense Collar is not permanently tied to one vest. It can be transferred between compatible Swanholm garments, allowing organizations to upgrade, replace, or adapt clothing while keeping the same connected safety technology.

Whether used for lone workers, industrial teams, logistics personnel, construction crews, or maintenance technicians, the Sense Collar provides a flexible foundation for connected worker protection.

Connected Safety Ecosystem Overview

Swanholm Technology is more than a safety garment manufacturer. It is a connected safety platform built around intelligent wearables, real-time alerts, and mobile connectivity.

The Ecosystem at a Glance

Swanholm Sense Collar
The wearable intelligence unit that monitors movement, detects falls, and manages alert workflows.

Swanholm Sense App
The mobile application used for pairing, configuration, emergency contacts, firmware updates, and alert management.

Swanholm Alert Vest
The high-visibility garment that houses the Swanholm Sense Collar and provides a comfortable, compliant platform for everyday use.

Connected Alerts
Emergency notifications triggered automatically or manually and delivered through the connected smartphone.

What the Swanholm Sense Collar Does

The Swanholm Sense Collar continuously analyzes movement using on-device Edge AI technology.

Rather than relying on cloud processing, motion data is processed directly within the device, enabling fast response times and reliable operation in the field.

Key Functions

AI Fall Detection

The collar monitors motion patterns in real time and can identify fall events that may require assistance.

Automatic Alarm Workflow

When a fall is detected, the system initiates an alert process through the connected mobile application.

Manual Alarm Activation

Workers can trigger an emergency alarm instantly using the collar’s physical button.

One-Button Simplicity

The collar is designed around straightforward operation, reducing complexity in stressful situations.

Hardware and Power

Built for daily professional use, the Swanholm Sense Collar combines compact electronics, wireless connectivity, and rechargeable battery technology.

2 × 1100 mAh lithium-ion batteries
Rechargeable through USB-C
Designed for reliable everyday operation

Charging

USB-C charging interface
Approximately 3 hours from 20% to 80% charge
Battery status visible within the Sense App

Connectivity

Bluetooth® 5.2 wireless communication
Secure pairing with the Sense App
Unique device identity linked to serial number

Device Identification

Each Sense Collar includes a unique serial number used for pairing, device management, and support purposes.

Swanholm Sense App and Firmware Management

The app serves as the central control hub for the entire safety platform.

Through the app, administrators and users can configure settings, monitor device status, and manage emergency workflows.

Timer Alarm Function

For high-risk tasks, users can activate a timer alarm. If the timer is not acknowledged before expiry, the system initiates an alert workflow.

App Features

Device pairing
Emergency contact management
Vest and collar configuration
Battery monitoring
Alert management
Firmware updates

Over-the-Air Updates

Firmware improvements are delivered wirelessly through the app, helping ensure devices stay current with the latest features and performance enhancements.

How the System Works

Swanholm Sense Collar monitors movement.
Bluetooth connects collar to the Sense App.
The app manages alerts and emergency workflows.
Emergency contacts receive notifications when alarms are triggered.
Firmware and settings are managed through the app.

Alert Logic and Emergency Workflows

The Swanholm Sense Collar supports multiple methods for raising an alarm.

AI Fall Detection Alerts

When a potential fall is detected, the system initiates a countdown sequence within the app. If not cancelled, an emergency alert is sent according to configured settings.

Manual Alarm

Users can activate an alarm immediately using the collar button whenever assistance is required.

Timer Alarm

Ideal for confined spaces, isolated work, or hazardous tasks where regular check-ins are important.

If the timer expires without acknowledgement, the system escalates the alert.

Smartphone-Based Communication

The Swanholm Sense Collar does not contain its own SIM card.

All alert communications are transmitted through the connected smartphone and the Swanholm Sense App.

Built for Long-Term Use and Portability

The Swanholm Sense Collar is designed as a reusable safety platform rather than a single-garment feature.

When a garment reaches the end of its service life, the collar can be transferred to a compatible replacement vest or jacket.

Benefits

Lower long-term ownership costs
Reduced electronic waste
Easier garment replacement
Consistent safety technology across multiple garment types

The collar is compatible with Swanholm garments both with and without active lighting systems.

Operating Conditions and Safety Considerations

For optimal performance, the Swanholm Sense Collar should be used and stored according to recommended guidelines.

Environmental Conditions

Store in a dry environment
Store at room temperature whenever possible
Avoid prolonged exposure to extreme temperatures

Temperature Considerations

Battery performance may be affected below -30°C and above +40°C.

Connectivity Requirements

Emergency alerts require an active Bluetooth connection to the paired smartphone.

Typical operating distance is approximately 8 meters without significant obstructions.

Important Notice

Fall detection technology can reduce response times and improve worker safety, but no detection system can guarantee identification of every incident.

False alarms and missed detections may occur under certain conditions.

Care and Maintenance

Proper care helps maximize product performance and lifespan.

Washing

Remove the Swanholm Sense Collar before washing the garment
Do not wash the electronic collar
Follow garment washing instructions separately

Charging

Charge regularly using USB-C
Avoid storing for extended periods with a depleted battery

Firmware

Keep firmware updated through the Sense App
Install updates when available

Storage

Store in a dry location
Avoid extreme temperatures
Protect charging contacts from contamination
