CES 2021: Hex Home Uses Wi-Fi Waves For Home Security Instead Of Cameras The Hex Home is a revolutionary take on home security Photo: Origin Wireless KEY POINTS The Hex Home uses Wi-Fi wave movements to detect motion in a house The Hex Home doesn't use any cameras, but provides more thorough coverage than traditional home security systems Home security has traditionally involved cameras and lights, but tech company Origin Wireless knew there was a better way to keep a home secured. Cue the Hex Home, a device that senses Wi-Fi waves to detect movement. Security cameras are pretty straightforward devices. They capture video feeds from where the lenses are pointed, and can often report to owners if there is any movement detected. The Hex Home is different in that there are no cameras. Instead, the Hex Home detects changes in Wi-Fi waves that are already bouncing around inside houses.
