Recently, a family friend reached out to share a puzzling and concerning incident . They had discovered a wallet, which had been stolen, left in an unusual spot on their property, a location that required someone to walk deliberately up their long driveway. Even more unsettling was that their back gate, which they always keep closed, was left ajar.
Naturally, I asked whether they had any security cameras installed. They confirmed that they had a Google Nest Wi-Fi camera, which is designed to detect movement and send immediate notifications and video to their smartphone. However, they received no such alerts. Upon testing the camera, it appeared to be functioning perfectly, raising questions about what had gone wrong.
Unfortunately, incidents like this could have highlighted a known vulnerability for homeowners relying on Wi-Fi-based security systems. Criminals are becoming increasingly tech-savvy, exploiting devices like Wi-Fi interrupters – small, inexpensive tools available online for under $100. These devices, although illegal to possess in Canada (1) can disrupt the functionality of Wi-Fi-connected cameras by interrupting their connectivity. This means that even though your camera may appear to be working, it won’t be able to send alerts or upload footage in real time.
Note – we have seen the use of similar digital devices to steal cars in Canada (2)
In jurisdictions across Canada and the United States, there have been reports of criminals using Wi-Fi interrupters to disable home security cameras before trespassing on properties. (3) Once the Wi-Fi signal is interrupted, the camera is effectively blind, leaving homeowners unaware of any suspicious activity.
While Wi-Fi cameras like Google Nest, Ring, and others are popular and convenient, however, they may not provide complete security on their own. Here are some additional steps homeowners can take to safeguard their property:
- Many security cameras now offer the option of recording footage directly onto an internal SD card. Even if a Wi-Fi interrupter is used, the camera will still capture and store images and videos locally on the SD card. This ensures you have a record of any activity, even if live alerts are blocked. Unfortunately, in our friend’s case, their camera did not have this feature, which could have provided crucial evidence.
- Unlike Wi-Fi cameras, hardwired cameras (e.g., those connected via Ethernet or coaxial cables) are immune to Wi-Fi interrupters. These systems can provide reliable surveillance without relying on wireless connections.
- Combining cameras with other security measures like motion-sensor lights and alarms can deter criminals. Even if your cameras are disabled, a sudden bright light or loud sound can startle intruders and alert you or your neighbours
- Some modern security systems come with cellular backup, which keeps them operational even if your Wi-Fi is interrupted. These systems can send alerts via cellular networks, ensuring you’re always informed of activity on your property
- As mentioned in the attached YouTube video if able, upgrade your router to the WPA-3 security setting, and
- Periodically test your cameras and other security devices to ensure they’re functioning as expected. Walk through your property to check whether alerts and recordings are working properly.
The incident with our family friend serves as a cautionary tale for all homeowners. While technology has made home security more accessible, it has also introduced new vulnerabilities. By staying informed and proactive, you can outsmart criminals and ensure your property remains protected.
Remember, a Wi-Fi camera alone may not be enough. Consider upgrading your system with local storage, hardwired cameras, or cellular backup to create a comprehensive security solution. Investing in layered security measures today could save you from potential headaches, and losses, down the road.
Although, we can’t say for sure that a Wi-Fi interrupter was utilized in this incident, it did have all the hallmarks of one being used.
