This device watches out for possible drownings in your private pool 24/7

The Coral Manta sends alerts to your smartphone if it detects a possible drowning

It is unfortunate that cases of drowning remain a perennial affair, but with the help of technology, we hope to see less of such incidents in the future.

Earlier this year, national agency Sport Singapore (SportSG) announced that it will install computer vision drowning detection systems (CVDDS) in 28 public pools that it operates. While this is great news, the fact remains that more people, especially children, experience drowning incidents in private pools, such as in condominiums and hotels, than in public pools.

Noticing this problem is local swimming pool solutions company Aquatech Products & Services, who have brought in the Coral Manta, a CVDDS invented by Israeli startup Coral Detection Systems that is meant for installation in private pools.

We speak to Marcus Soo, business development manager at Aquatech, to share with us the key features of the Coral Manta and why it makes an important safety investment.

1) How does the Coral Manta work?

Using computer vision and artificial intelligence, the Coral Manta monitors the pool using its built-in underwater video camera. Programmed to detect drowning by identifying sinking bodies that show a lack of movement, it sets off the alarm within seconds of the device identifying a case of drowning. Once the Coral Manta sounds the alarm, it also simultaneously sends an alert to your smartphone. 

The speed of drowning identification and alarm sounding reduces the chance of brain damage caused by oxygen deprivation that typically occurs after 4-5 minutes for children, and 3-4 minutes for adults.

Charged by solar power, the Coral Manta is on constant watch 24/7. 

2) What is the difference between the Coral Manta and other CVDDS designed for public pools?

Unlike CVDDS for public pools which are designed to assist life guards, the Coral Manta is designed to be more accurate and have a higher detection rate so that the incidences of false alarms are lower. CVDDS for public pools can afford to have a higher margin of error since the lifeguard is present and can dismiss false alarms.

3) How many units of the Coral Manta is recommended per pool? 

MS: The Coral Manta has been tested to be optimally effective in pools of around 10 metres long. 

4) What are some factors that can affect the effectiveness of the Coral Manta?

Water clarity is crucial since the device depends on visual detection of drowning. The Coral Manta also requires a direct line of sight of the entire pool to be effective, which is why it is typically installed at a corner of the pool. If the pool is an odd shape that results in blind spots, more units of the Coral Manta should be installed at those irregular corners. 

5) How much is a unit of the Coral Manta?
