This is a new gadget by Walabot, a product from Vayyar Imaging. The company says that "All Walabot devices are created to help you uncover hidden things in the world around you. The technology is based on 3D imaging sensors that use radio frequency, rather than a camera, to see through solid surfaces and create a visual image of what’s inside." The company already makes a 3D DIY device to let see people see through walls to find wiring, pipes, etc. Walabot Home, their newest gadgets, is a 3D sensor that can “see” through walls and detect motion. It mounts on a wall and is said to be able to detect if someone has fallen and well - can't get up. When Walabot detect a motion like a fall, it will automatically place a call for help to the selected contact without the fallen person needing to push a button or even be wearing a device. So that's great for an elderly person taking a shower or a bath, especially since there is no camera needed in the room. The company says it can even can detect if someone stops breathing. Another neat feature is that a person who wants help can also just push a button on the device to summon their emergency contact. The cost is $149.99 + $4.99 a month, with the 1st 6 months free.
