Security expert Gina Field, founder of Nepean Regional Security, joined Jenny to discuss the emerging risk of Wi-Fi jammers, also known locally as Wi-Fi blockers, and how they can interfere with some wireless home security systems. The discussion followed reports from Melbourne where a luxury vehicle was allegedly stolen after a blocker prevented the homeowner from accessing camera footage.
Gina explained that while police are not yet seeing widespread use of these devices in Australia, they are already a significant issue overseas and are beginning to appear locally. These blockers work by disrupting the Wi-Fi network that many DIY security cameras rely on, which can prevent footage from being downloaded or accessed after an incident. Although the devices are illegal, Gina noted that they can still be purchased online, creating a growing concern for homeowners relying solely on wireless systems.
Her advice was to have a backup plan. For those using DIY Wi-Fi cameras, Gina recommended choosing models with SD card storage so footage can still be retrieved if the internet connection is blocked or drops out. She also encouraged households to use strong Wi-Fi passwords, avoid common personal details such as pet names or dates of birth, and set up alerts where possible so they are notified if their Wi-Fi connection goes down.
Gina also reinforced the importance of returning to practical, layered security. This includes sensor lights, physical locks, locked windows and doors, stronger door screws, alarms, hardwired cameras, dogs, steering wheel locks, bollards, gravel driveways and even bells on gates. Her key message was that technology has a role, but simple, visible and physical deterrents remain some of the most effective ways to reduce the risk of break-ins and vehicle theft.
