Glossary – our terms & ISO 20380 definitions

The language that we use to describe your drowning detection system.

This glossary is provided in a sequence that best describes computer vision detection systems to those that are unfamiliar with the technology.

** denotes terms referenced from ISO 20380:2017

ISO 20380

The document produced by the International Organisation for Standardization (ISO), which guides our niche industry sector (computer vision detection systems for public swimming pools).

Computer vision detection system

The technical name of a drowning detection system.

Digital Lifeguarding

The SwimEye concept of adding technology to traditional lifeguarding techniques.

Pool basin

Another name for the swimming pool or the actual structure containing water.

Camera location

The physical position of an underwater camera installed within the pool basin.

Monitoring **

Active and constant observation (by cameras) of people in the pool basin, with the aim of preventing drowning risks.

Monitoring overlap

The SwimEye philosophy of providing overlap in monitoring.  This occurs when two different cameras analyze the video stream (in one part of the pool) from two different directions.

Monitoring zone

The area which each underwater camera views and provides monitoring.

Detection **

Active recognition of a total and prolonged immersion of a stationary solid mass (such as a person or object) at the bottom of the pool basin.

Alarm Situation/potential drowning incident

A situation when SwimEye detects a person (or object) that remains stationary on the bottom of a swimming pool.  Another name for detection.

Early Warning Alarm
(Yellow Alarm Status)

This indicates that a potential drowning incident may be occurring. SwimEye provides a visual electronic alert at the Monitoring and Control Station if detection occurs.

Drowning Alarm
(Red Alarm Status)

This indicates that a potential drowning incident may be occurring, and immediate lifeguard response is required.   SwimEye provides a full electronic alert at the Monitoring and Control Station and portable radios if detection remains after a prescribed period of time (known as the alarm set off time).  

Alarm set off time **

Time from the moment that person or object is fully immersed, on the pool bottom of the pool and stationary, until the drowning alarm is activated.

Drowning incident location

The actual/physical location of a drowning incident in the pool basin.

Electronic alert

Alert produced when detection occurs.

Electronic alert (audio)

Audio alert produced when detection occurs, in the form of an audio alert from the Monitoring and Control Station or portable radio.

Electronic alert (text message)

Alert produced when detection occurs, in the form of a text message provided to the portable radio.  The text message explains the drowning incident location in two methods.

  • Name of the pool.
  • The physical location within that pool (the radio alert zone).

Radio alert zone

The division of the pool basin into smaller areas, to assist in the translation of the drowning incident location into the electronic alert (text message).

Radio alert zone name

The nomenclature used to define each radio alert zone so that lifeguards can understand the drowning incident location following the provision of an electronic alert (text message).

False alarm

An alarm set off for reasons other than detection, which can be split into two categories:

  • False alarms preventable through Digital Lifeguarding techniques.
  • Genuine false alarms caused by technological limitations.

Preventable false alarm

False alarms set off by preventable issues including:

  • Sudden changes of indoor lighting,
  • Use of maintenance equipment on the bottom of the pool,
  • Underwater elements like a movable floor or underwater rugby goals,
  • Objects in the pool for example, forgotten toys, etc…

Genuine false alarms

Real false alarm situations, caused by current technology limitations:

  • Unstable or changing light conditions and shadow.
  • Hardware faults.
  • Software errors.

Reset SwimEye

The process of deactivating monitoring:

  • Deactivation is typically used during pool maintenance or cleaning, so that preventable false alarms do not occur.

Monitoring blind zones

In some cases, a drowning detection system may not provide complete monitoring of a swimming pool.

  • Areas outside of the monitoring zone are called monitoring blind zones (or non-detection zone, area of unstable detection)

Test Area

Position or area within the pool basin where a system test (otherwise known as a detection test or rescue dummy test) is undertaken.
