Z-Works Heat Beat Sensor is a compact Z-Wave Plus compatible device that can monitor up to 3 meters heart rate, breathing rate and activity of an individual. Once plugged to the wall, the sensor relies on 24 GhZ-frequency wave to analyze internal body movement and collect one's vital data. It can be used for example to ensure that a person laying in a bed is alive at night. Thanks to its 1/4" diameter socket used by the large majority of cameras, it can be attached to most tripods and suction pads for an easy installation.
