Like Wi-Fi, the device sends out mmWave radar signals that scan the environment using harmless radio waves a thousand times weaker than a cellphone. Vayyar HOME detects a person’s body position, a fall, or health problems. It’s mindful of privacy, because it doesn’t use cameras. Setup is also simple for out-the-box use, with pre-configured settings available for installers. It’s US and CE certified, UL1637 approved* and approved for use across the United States, Europe, Canada, Australia and Japan.
