Xandem Technology uses radio waves to monitor movement - CES 2014

The video explains the concept of mesh radio networks, which use low power radio devices called nodes to form a network that can detect and locate motion within a defined area. This technology is useful in security and elder care applications as it can detect movement through walls and obstructions. The video also discusses the application of this technology for SWAT teams, allowing them to monitor motion within a space using a tablet or computer.
