Computer vision based drowning detection system

CORAL MANTA is the first and only computer vision based drowning detection system for residential swimming pools. This innovative drowning detection system uses Artificial Intelligence technology to track everyone in the pool and detect risk of drowning 24/7. The system is powered by solar energy.
Existing pool safety devices such as fences, pool covers or mechanical alarms merely attempt to prevent unauthorized access to the pool. But they become useless when someone is already in the pool (whether authorized or not). In contrast, CORAL MANTA "watches" the pool 24/7 when there are people in the pool and when the pool is not in use. Moreover, while existing alarms require you to deactivate and reactivate when using or exiting the pool, with CORAL MANTA you do not need to worry about forgetting to activate or deactivate, covering or uncovering, locking or unlocking anything. CORAL MANTA is on the lookout nonstop, day and night.
The system constantly monitors the pool with its built-in underwater video camera, using computer vision and artificial intelligence technology and is programmed to detect people in the pool as well as their position and motion. Using this technology it constantly analyzes the real time video that it captures from the underwater camera and whenever it identifies a near drowning event it generates an alarm. Simultaneously and just in case you are not around, it is sending alerts to all household members via their smart-phones / tablets.
Imagine floating on the water and then breathing out all the air from your lungs. You probably know the feeling of sinking and the immediate urge to breath in to keep afloat. Without air in your lungs, your body sinks. Accordingly in most cases, when a person drowns he or she sinks to the bottom quickly. CORAL MANTA identifies such a situation and sets off an alarm.
For children, irreversible damage to the brain tissues typically starts to occur after about 4-5 minutes without oxygen, (for adults it is after about 3-4 minutes). The drowning detection system detects when a person sinks, meaning seconds after she or he stopped breathing, and it sets off a series of escalating alarms within seconds. This gives you ample time to get the person out of the water, and start CPR or any other essential action. People who drown and are removed from the water within such a time frame have very high chances of surviving without any damage.
Adult supervision is always required.
During the development process CORAL MANTA was tested in thousands of scenarios simulating drowning events, in a wide variety of swimming pools, with adults and children.
CORAL MANTA is using Artificial Intelligence technology that constantly continues to "learn" and improve, and even to adjust to your own pool and comes out of the box with a lot of "knowledge" that enables it to detect most drowning events, while generating minimum false alarms. But, your pool may have different and unique features that CORAL MANTA never "saw" before. Thus, in the first couple of weeks, it may generate more false alarms than usual. When there is a false alarm, using your App, you can tell CORAL MANTA to ignore it, and this is how it learns and the rate of false alarms will drop dramatically to close to zero.
