Thanks to a Netherlands based company, home security systems may start implementing motion detection sensors through Wi-Fi signals. The company, called Gamgee, has found a way to utilise the waves that Wi-Fi generates throughout the home as a way of detecting intruders. What’s more, you wouldn’t need additional equipment to make it work.

How Sensors Work

In terms of home security systems, most alarms will need a combination of different sensors, such as passive infrared (PIR) motion sensors, entry locks and cameras. Each of these things need to be fixed statically to be able to do their job, often requiring to be wired in. Even if not, there’s usually restrictions about where these items can be placed.

Technology has allowed advancements in cameras to detect faces and for motion sensors to be alerted by heat radiation. However, these systems are rarely best suited to be standalone security items, needing to be used in conjunction with others. You wouldn’t, for example, only have contact sensors in your home without a camera or an audible alarm.

Making Use of Wi-Fi Signals

Currently going through its testing phases, the Gamgee system works by monitoring alterations in the waves your Wi-Fi router emits. As people pass through these waves, it alters how internet signal travels. With the use of AI, the system will be able to differentiate between people and pets, as well as static objects and different rooms.

Because of the prevalence of the internet, the majority of homes will have Wi-Fi, which is constantly sending out signals and waves through the property and immediate area. The best part about Gamgee’s security solution is that no extra equipment is necessary. It offers a solution that can cover the whole home without any blind spots.

Identifying Occupants

Thanks, in part, to AI, the Gamgee system will be able to learn how to identify members of the household. It does this by assessing how they disturb the Wi-Fi signals as they navigate the home, which then makes it easier to detect intruders. Because pets aren’t permanently stationary, their effects on Wi-Fi signals will also be crucial to avoid false alarms.

Personal Data

Although Wi-Fi signal can still be found outside the home, there is no risk of personal data leaking out. The system is designed to work locally, without compromising sensitive data. You can even control how it works from your smartphone.

Wider Applications

As an all-in-one solution for both broadband and home security, this system offers real value to consumers. Not only this, but the technology could present itself to other uses, such as for energy saving. As it’s all integrated into the broadband router, it could be useful if no additional equipment is necessary.

If all broadband providers were to implement this technology into their systems, there’s the potential for healthy competition and deals through the mobile app. By removing some of the hassle involved in installing home security systems, making use of Wi-Fi could be a step in the not-so-distant future.
