For station and network operators. Count rules show when a platform passes its threshold, and an item left on a concourse is brought to an operator to check. Line rules cover the track edge and one-way passages.

This sector is in our industry directory rather than among the six primary markets. We have not developed a full workflow or pilot plan for it yet.
Where it is used
Who it is for
- Station control room
- Network operations
Track edge
A line along the platform edge, crossed towards the track.
Pedestrian flow
People counted in each platform and concourse camera's view, with thresholds.
Direction
A one-way passage walked the wrong way, or a bus lane driven the wrong way, each with its own rule.
Events of interest
Events for platforms, concourses and passages.
Each says what it needs and where it stops. The rules you set on a camera raise these events, and the alerts that go with them.
Line crossing
A person or vehicle crosses a line you draw, in the direction you choose.
- When
- A followed object crosses the line one way, the other way, or either way.
- Limit
- An object that is only partly in view near the line can be counted as crossing, or missed. A crossing inside the rule's repeat limit is not recorded.
Wrong-way movement
A vehicle, or a person on foot, crosses a line against the permitted direction. Each rule names the object type it applies to.
- When
- A line crossed in the direction the rule forbids.
- Limit
- A vehicle reversing briefly, or a person stepping back, crosses the line the wrong way.
Crowd gathering
More people are in a camera's view at once than the number you set.
- When
- The count of people in the camera's view reaches the threshold.
- Limit
- A count of people the camera can see, not a calibrated density and not a count inside a drawn zone. People hidden behind others are not counted.
Item left behind
A bag, case or stopped vehicle stays still beyond the time you set.
- When
- A backpack, handbag, suitcase or vehicle stays still past the limit.
- Limit
- Only the detected item types are covered, anywhere in the camera's view. A bag beside its seated owner can be reported.
Occupancy threshold
The number of people or vehicles in a camera's view reaches the capacity you set.
- When
- The count of the chosen object type reaches the threshold.
- Limit
- It counts what one camera can see, so a space covered by several cameras needs a rule on each.
Person on the ground
A scene reading describes a person lying or collapsed on the ground.
- When
- The reading of a sighting carries the person-on-ground tag.
- Limit
- It follows the reading, so it is not an immediate fall alarm. People sitting or resting can be read as on the ground.
Use cases
What a station control room uses it for.
What the current release does for this kind of site.
Track-edge crossing
An alert when a person crosses the line towards the track
Platform count thresholds
An alert when the people in a platform camera's view pass a number
Wrong-way pedestrians
A one-way passage or escalator approach crossed against the flow
Wrong-way vehicles
A bus lane or forecourt driven against the permitted direction
Item left on a concourse
A bag left still beyond a set time, for an operator to check
Passenger counts by hour
People counted for each camera, by quarter-hour, hour or day
What it needs
- A line drawn along each platform edge and across each one-way passage
- Thresholds agreed for each platform and concourse
Boundaries
- A track-edge rule reports a crossing after it is seen. It is not a train-protection or platform-safety system.
- Wrong-way rules are written per object type: a rule for people in a one-way passage is separate from a rule for vehicles in a bus lane.
- Platform figures are counts of people in view, not a calibrated density.
- Fights are not detected.
Capabilities used
The same platform. Different rules.
Each site gets its own cameras, modules and rules. Nothing is custom-built; everything is configured.
Review platform and concourse rules on a station.
Choose one platform and its concourse. We will show the count thresholds, the alert queue and the line rules on footage from them.
