We use the router in our home to connect to the internet, but it can do quite a bit more. Comcast shows that with Xfinity Shield, which has turned millions of devices already installed in homes into sensors capable of detecting movement through changes in the Wi-Fi signal. The same router, but now with the ability to monitor activity inside the home.
Wi-Fi can also detect movement
The new feature, called WiFi Motion, is rolling out to compatible routers through an update to the Xfinity Internet app and is available on XB7 gateways and later, as The Verge reports. If we turn it on, the system works by analyzing the small changes between the router and the devices connected to it to identify activity. The alerts, if there are any, appear directly in the app just like with any conventional motion sensor.
Now, what can we do with it? Comcast offers the Home Watch, Away Watch and Dark Watch modes to adjust detection based on whether we’re at home, away, or during nighttime hours, respectively.
Home automation is growing quickly. We’ve seen it with the arrival of Matter and compatible devices and also with Apple’s plans for a smarter home hub. In this context, radio-frequency detection is gradually gaining ground in home automation, since it allows enormous flexibility when it comes to automating, protecting and coordinating.
