Object tracking
A moving object is easy to count twice.
Your product has to follow each object and count it once, in a zone or across a line. We do it with object detection and multi-object tracking, and help you build it in.

How it works
From your camera to a count per zone
Objects cross paths, stop and disappear behind each other. Tracking gives each one an ID and follows it, so it's counted once, in the right direction.
Your system: Objects
People, vehicles or goods moving through view.
Your system: Camera
Your camera, above a doorway or across a yard.
Our solution: Object detection
Finds each kind of object you choose, in every frame.
Our solution: Tracking
Follows each object by ID, so it's counted once as it crosses a line or zone.
Your system: Zone dashboard
Shows the count in each zone and across each line.
What it handles
Counts each object once
We tune it to your scene, then check each count against a hand count of your footage.
What it tracks
- Busy scenes
- Many objects in view at the same time.
- Brief hiding
- Objects hidden for a moment, then back in view.
- Both directions
- Movement into and out of a zone, either way.
- Speeds and sizes
- Slow and fast objects, near and far.
- Overhead or angled
- Above a doorway, or looking across a yard.
What it ignores
- Shadows
- Shadows moving across the scene.
- Lighting changes
- Daylight, clouds and lights switching on and off.
- Standing near the line
- Objects that stop close to the line without crossing.
- Reflections
- Reflections in glass and on shiny floors.
- Other objects
- Objects of other types passing through.
