Origin Wireless has developed a series of algorithms that can use the signal from mesh Wi-Fi networks to detect motion in a room, according to Engadget.
The development of this and similar technologies could have major implications on home-security systems and other home-monitoring solutions, offering companies new, simpler ways to detect movement in a home or business.
The setup uses a transmission mode on the mesh-enabled Wi-Fi routers that’s typically reserved for initial configuration, with one router acting as a transmitter and others as receivers. The transmitting router sends out signals that bounce around the room before eventually reaching the receiver, and the software can monitor how long this takes. When something moves in a room, that causes a change in the way those signals bounce around, leading to differences in the amount of time between transmission and reception along a given pathway, which the software can interpret as movement.
Origin’s motion-detection software could enable a variety of home-monitoring solutions that eschew the need for cameras or specialized sensors. A device like a Nest Cam home-security camera, for instance, records video streamed from a purpose-built device and uses cloud-based artificial intelligence (AI) tools to determine if there’s movement. Systems like Xfinity Home use dedicated motion sensors to monitor rooms for movement. While both types of systems — especially camera-based solutions — provide much more specific data than Origin’s algorithms can derive from Wi-Fi routers, they also require additional hardware, whereas more and more homes feature mesh Wi-Fi coverage, which means monitoring could be enabled just through software updates.
This type of monitoring system has applications beyond the burgeoning home-security market. Origin’s…
