Enhancing beach safety with integrated shark spotting systems

The NSRI's Station 14 in Plettenberg Bay has made significant strides in beach safety by integrating advanced beach safety cameras and shark alarm systems.

This innovative system rolled out over the festive season, marks a collaborative effort between the NSRI, local lifeguards, and municipal authorities to enhance the safety of beachgoers.

"We have successfully installed a shark alarm on top of the NSRI building and a repeater further down the beach," says Station Commander Jaco. "This setup covers Central Beach, Hobie Beach, and The Wedge. Additional installations are planned for Robberg 5 and Lookout Beach to ensure comprehensive coverage."

Contrary to common perception, these are not shark-specific cameras. "These are beach safety cameras with shark warning alarms. The systems are designed for general water safety, incorporating audible sirens and visual indicators."

The alarm system uses a red signal for high shark activity, prompting an evacuation alarm when necessary. The system's advanced technology includes a pan/tilt/zoom (PTZ) camera with a 214mm optical zoom, allowing precise observations up to 5km away. Features like laser focus, hydrophilic lens coating, and superior low-light performance make it ideal for marine environments. The NSRI Emergency Operations Centre (EOC) remotely controls and monitors these cameras, with assistance from volunteers.

Collaboration is key to the success of this initiative. "We formed a shark action group and integrated roles with lifeguards and shark spotters," Jaco explains. All permanent lifeguards and shark spotters have completed relevant training, including the Coastwatchers course. This cross-training enhances their ability to coordinate effectively. "We even have the use of a jet-ski that they send out to patrol for potential sightings. It's operated by the lifeguards, and they can patrol up and down to warn people of any shark activity."

Protocols are in place for swift action when sharks are spotted. "The response depends on the species and conditions," says Jaco. Beaches typically close for 20 minutes if a shark is monitored and tracked. In murky water, closures can last up to an hour. "It's all about continuous communication between beach control and lifeguards," he adds.

Volunteer participation plays a vital role. Lezhae, a key member of the beach safety team, monitors cameras during peak periods with the help of volunteers. "We're expanding the team and welcome anyone with a stable internet connection and a PC. We provide training so they can assist remotely," she shares. "It's all about working together to save lives."

Looking ahead, additional shark alarms will be installed at The Wreck, Robberg 5, and Lookout Beach. More cameras will enhance coverage, further solidifying Plettenberg Bay as a leader in proactive beach safety.
