- What it answers
- Where exactly, and where have they been?
- How it works
- TraceGuard calculates locations to pinpoint workers on the floor plan.
- Hardware per area
- One card per worker, three to four beacons spread across the area.
- How good the answer is
- Accurate to about 2 to 5 metres, in rooms up to 20 metres across.
- What you get from it
- Live coordinates, the route somebody walked, and heatmaps by contractor and date.
- Better handled by
- ZoneSentry, when you can only fit one or two beacons, or the structure is heavy on steel and concrete.
SMARTSITES / DETECTION SYSTEMS
ONE SITE.
FOUR WAYS TO SEE IT.
ZoneSentry, TraceGuard and GateKeeper are three ways of answering the same question: where is this worker right now. SmartCam answers a different one. You can run all four on the same site, and they all write to the same attendance record.
Colored areas show where the three tracking methods are used. The cards explain what each one tells you.
TraceGuard
WHERE EXACTLY IS THE WORKER?
TraceGuard calculates locations to place workers on the floor plan. That continuous position is what makes movement paths, historical replay and heatmaps possible. Anything that needs to know not just which room, but where in it.
- CONTINUOUS POSITION
- MOVEMENT HISTORY
- HEATMAPS
- BeaconThree or four spread around the area. The more that can hear the card, the tighter the position.
- Route walkedEvery position joined up in order. This is what you scrub through when replaying a day.
- Time spentThe warmer the patch, the longer people stood there. Built up over a day or a date range.
- Current positionWhere the worker is now, accurate to about 2 to 5 metres.
ZoneSentry
WHICH ROOM OR ZONE IS THE WORKER IN?
ZoneSentry tells you which room somebody is in by naming it, not by calculating a point on a map. Every room is described by what its radio signal looks like, and the system picks the room whose description fits. It is the default, and it holds up better than anything else when a floor only has a couple of beacons on it.
- ROOM IDENTIFICATION
- ZONE OCCUPANCY
- ROOM TIME
- BeaconA small box on a wall or ceiling. It listens for cards and reports how close they are.
- Tracked roomA room you have drawn on the plan. The count is how many people are in it right now.
- No-entry areaA room nobody should be in. Anyone who walks in raises an alert immediately.
GateKeeper
WHO CROSSED THIS POINT?
GateKeeper watches a doorway instead of a room. A sensor on the frame sees who enters and writes an entry or an exit. Where an area has specific entrances, that is a measurement and not a guess, which makes it the most dependable tracking we offer.
- ENTRY / EXIT
- CROSSING LOG
- LIVE HEADCOUNT
- Door sensorSits on the door frame. Sees who enters and uses Bluetooth to see whose card it was.
- WorkerGoing in counts them into the room. Only coming back out takes them off the count.
- Tracked roomThe count only changes when somebody actually crosses the doorway.
SmartCam
WHAT DOES THE SITE SEE?
SmartCam is the one system that does not follow a card. Footage from a site camera goes through detection models, and the same clip answers more than one question: whether the gear is being worn, and how much of the watched time is real work.
- VISUAL DETECTION
- PPE EVIDENCE
- SITE ACTIVITY
- CameraCovers one work area. The shaded wedge is roughly what it can see.
- Detection boxEach person the model found in the frame, with what it did and did not spot them wearing.
SHARED SYSTEM
ONE SITE.
ONE DATA LAYER.
The tracking method belongs to the room, not the site. A floor sets a default and any room can override it, so one level can run all three at once.
