Can Underwater Surveillance Help Prevent Drownings?

Courtney Cameron Headshot

The city of Edmonton has recently issued a Request for Proposal for the installation of underwater cameras in response to concern over their growing drowning rates. The cameras, also called an Underwater Drowning Prevention System, are a relatively new technology that aid in surveillance and recognition of emergency situations. 

According to Jerry Johnson, business unit manager of North America for Poseidon, a manufacturer of the cameras, the technology is focused on tracking movement. When the camera detects that a person has been motionless for more than ten seconds, it sounds an alarm on a device carried by lifeguards alerting them to the situation and giving them a visual of the location of the emergency. On a global scale, Johnson says the technology has resulted in approximately 30 additional lives saved during the past 15 years.
