Swimmer tracking.
Follow visible people and their movement through suitable camera footage, with detections and trails for water-safety teams to review.
Follow the movement
Follow visible people and their movement through the camera view.
How tracking works
A track connects detections over time, so the operator can follow a person’s movement within the view. Counts and zones can add information about where water users are gathering or moving.
A person obscured by waves, glare, rock features or other people may leave the visible track. The analysis and evaluation must account for those gaps; a track does not establish identity.
Notice the event
Define the water-entry or movement event your team needs to notice.
Water-entry event criteria
A distress-related event is a defined observation that the operator wants to review. Unexpected water entry from a monitored platform is one concrete example used in the SAIL programme.
Define the subject, zone and observable behaviour for the task. The alert directs attention to evidence; the operator assesses the person’s situation.
Know what the camera can tell you
Camera observations support assessment. They do not establish whether a person is safe.
What a camera observation establishes
Drowning is an outcome, while camera analytics work with visible people, movement and events. A useful evaluation asks whether the agreed observation can be detected and reviewed in time to inform the operator.
The absence of an alert does not establish that a person is safe. Coverage, visibility and the response workflow remain essential parts of the operating proposal.
Measure what matters
Assess missed events, false alerts and useful information for the team.
How tracking is evaluated
Assess whether the person and event are visible, whether the track is useful and whether the alert arrives with enough footage for review. Measure missed events and false alerts across the camera’s operating conditions.
Record delivery, operator acknowledgement and response separately. This helps the team understand both the analysis and its workload.
Account for the conditions
Light, sea state, target size and occlusion shape what the camera can show.
Conditions that affect tracking
Target size, sea state, light, spray and occlusion affect what the camera can show. Moving PTZ and aerial views need a separate assessment from a fixed coastline view.
Bring examples from difficult conditions as well as the clearest footage. Check camera suitability.
Define the task
Start with an event, a camera view and the team receiving the information.
Camera assessment requirements
Tell us what your team needs to notice and who would review it. We can assess one view, identify the suitable capability and explain the next step in a written recommendation.
Background and context
ResQVision detects people and follows their visible movement across a camera view. For water-safety tasks, that includes swimmers, waders and flotation users, alongside configured events that warrant attention.
Tracking helps an operator follow activity. Event detection helps identify which change to review. Together they make a camera feed more useful to the people monitoring the water.
