How AngelEye LifeGuard Works

AngelEye systems are designed to enhance pool safety and lifeguard effectiveness by detecting underwater objects that stop moving for more than a few seconds. Submersion incidents happen quickly and without warning, and can turn into a drowning in as few as 20 seconds. It is during this critical period that AngelEye LifeGuard provides the greatest layer of additional safety to an aquatic facility.

AngelEye Camera

AngelEye tracks every swimmer in a single or multi-pool configuration, at the location it is needed most—in the water and in areas of greatest danger.

AngelEye’s advanced AI software and monitoring system analyses swimmer behavior and detects the absence of movement or ‘non-purposeful’ movement (which doesn’t allow a swimmer to reach the surface to breathe) and initiates an alarm if a critical-period threshold is exceeded (usually 7-12 seconds).

The warning alarm is transmitted wirelessly to lifeguards using AngelEye smartwatch technology, enabling responders to see real-time video and the exact location of the submerged swimmer in the pool.

Advantages of AngelEye LifeGuard



True underwater, advanced-monitoring technology reduces the negative impact of glare, shadows, and low-visibility areas that can limit lifeguard effectiveness

Can be implemented in multiple pools to monitor both active and inactive areas

Recorded video can be saved and used to document critical incidents and train lifeguards on best practices for mobilizing an emergency response to a submersion threat

Allows for remote monitoring for authorized users and provides recording and cloud data storage in the event of a submersion incident

Dedicated AngelEye IT specialists provide off- and on-site support

Components of the AngelEye System

Technology Serving the Needs of Aquatic Safety

AngelEye Camera

The ‘eye’ of the AngelEye system is an integrated camera that combines efficient LED lights and a video camera that is able to track the most subtle movements of swimmers in the water.

The cameras are exceptionally durable and provide a clear view of critical areas, such as the bottom, areas around edges and ledges, and near drains and grates. They are also compliant with the Model Aquatic Health Code (MAHC) and national and international competition standards.

In most configurations, AngelEye can be installed in a pool’s existing light niches without having to drain the facility, thereby reducing the time and costs of installation.

Software Detecion Monitoring

At the heart of the system is a proprietary software and threat-detection algorithm that separates AngelEye LifeGuard from anything on the market. The intelligent software analyzes sectors of the pool on a grid, which is optimized for every individual facility, and ‘learns’ from the data that is collected to improve performance over time.
Unlike above-water camera systems, which only provide the last-known position of a submerged victim, AngelEye LifeGuard tracks both lateral and vertical shifts underwater. Most above water systems that purport to detect submersion, only register when a victim remains underwater; however, they are unable to analyze paradoxical movement across lanes or down the surface of a transition to a deeper part of the pool.

More impressively, the system accounts for ‘non-purposeful movement’ in a submersion incident lasting more than 12 seconds. Non-purposeful movement is defined as movements that do not allow a swimmer to break the surface, either to breathe or to signal distress to lifeguards.

Wireless Alerts and Wearables

AngelEye Technologies believes that a lifeguard’s first responsibility is to keep eyes on the water, not looking at monitor. For this reason, any warning alarms generated by AngelEye LifeGuard are directed to first responders via waterproof smartwatches connected to the system. The ruggedized units are configured to provide only the most critical information during the time of an alert: a real-time picture, coming from the underwater camera, with high-visibility identification target, and the exact location of the potential threat. Warning alarms on the wearable units are tactile (vibration) to eliminate confusion in environments with loud ambient noise and to reduce alarming the general public with strobe lights or sirens. AngelEye wearables quickly and easily become part of a lifeguard’s ‘essential gear’ for mobilizing a response to a submersion incident or rescue.
