A small BLE beacon, clipped to a fire extinguisher or worn on a lanyard, is enough to know exactly where it’s been. Collie’s beacon network puts every tracked asset and person on a live floor plan, keeps a history of how they moved, and tells you the moment a device needs a new battery.
Why it matters
A misplaced tool, an unaccounted-for worker during an emergency, or a piece of equipment nobody can locate — all solvable with a signal cheaper than a keychain.
Fire extinguishers, tools, and mobile equipment drift from where they’re supposed to be — and searching for them wastes real working hours.
When something goes wrong on site, knowing exactly who’s where — for rescue and recovery — shouldn’t depend on a headcount and guesswork.
Without movement history, there’s no way to see how assets and staff actually flow through a site — data that’s often the key to optimising a warehouse layout.
What’s inside
Every tracked beacon appears as a dot on your building’s actual floor plan, positioned in real time using signal strength.
Play back where a person or asset has been over the last hour, day, or week — a trail, not just a dot.
Battery level and last-seen time for every tag, so a dying beacon gets swapped before it goes dark, not after.
Get notified the moment a tracked asset or person enters or leaves a zone they shouldn’t — a restricted area, or simply the building.
Beacon types
Beyond position, different beacons read different things — chosen per asset, not one-size-fits-all.
A basic BLE tag for location — clipped, stuck, or worn, tracked purely by signal strength.
Keychain or card-format tags designed to be carried or worn for continuous personnel tracking.
Accelerometer-equipped beacons that detect strong movement or a fall, and trigger an alert automatically.
Beacons with a temperature or humidity probe, from freezer monitoring to ambient job-site conditions.
Detects a magnetic field to sense whether a door, cabinet, or panel is open or closed.
Detects nearby objects or people at close range — from occupied seats to a bin that’s nearly full.
Detects water leaks or liquid level changes, useful for facilities with sensitive equipment nearby.
Reads dry or wet contact and high/low signals from third-party equipment, feeding them into the same platform.
How it flows
Each beacon broadcasts a signal at a set interval, picked up by nearby gateways scanning continuously.
Signal strength across multiple gateways places the beacon on your floor plan — no GPS needed indoors.
Every position update builds into a movement history, ready to review, export, or replay later.
Beacon tags are inexpensive, battery-powered, and stick-and-forget — some run for years on a single charge, with no wiring and no ongoing maintenance.

Fixed gateways cover fixed floors. A Collie robot on patrol can carry a beacon gateway with it — picking up tagged assets and personnel in aisles, yards, or outdoor areas that a wall-mounted gateway would never reach.
Where it’s deployed
Warehouse asset flow and utilization, tracked to optimize layout and reduce search time.
Critical equipment tracking — infusion pumps, wheelchairs — so nothing is ever “missing”.
Security officer patrol tracking, confirming rounds were actually completed on schedule.
Worker tracking across a site for both safety and rescue & recovery scenarios.
They can operate autonomously or semi-autonomously with human supervision depending on use case.
Yes, our platforms are designed for seamless integration with enterprise systems.
Construction, healthcare, aviation, manufacturing, security, and more.
