If you want to improve the security of your home but don't want to attach cameras or detectors to your living space, instead you can consider using your router. Linksys has launched Linksys Aware, a new motion sensing subscription service that uses information from Velop mesh routers to track a home using WiFi signals.

The system senses activity in the house and sends alerts via the Linksys app to users ' smartphones. When consumers do not want to be interrupted, such warnings can be switched off or snoozed, and it is also feasible to calibrate the sensitivity of motion detection in different homes to avoid false alarms.

Linksys does not explain how the technology works precisely, but other implementations of motion detection using mesh networks have studied WiFi signals to detect "noise" in wall-bouncing signals. They change the way the WiFi signals bounce when a human walks into a room, and the router will sense it.

Linksys says that as well as its usefulness as an intruder alarm, the device could be used to help the aged with remote treatment. Historical data on house movements will be valid for up to 60 days and in monthly, daily and weekly scales can be accessed through the app.

In most nations, the service provides on today's Linksys Velop routers and will actually roll out to other Linksys mesh routers as well. Users can update the firmware of their device, download the app from either the App Store or the Google Play Store, and try the service for 90 days free of charge. It's going to cost $2.99 a month or $24.99 a year after that.
