The health-monitoring system includes one or more cameras which collect graphic data and a controller which calculates body proportion measurements based on the graphic data. Specifically, the health-monitoring system measures a user's body parts and their relative positions. These measurements may be combined with those collected by other devices and sensors within the system which conduct other health-related measurements. The other devices and sensors may be housed within a container and a least one of the cameras may also be housed within the container. In some embodiments, the container is a fixture, such as a bathroom medicine cabinet . The camera may be invisible to a user as positioned within the fixture. Consequently, the user may move and behave normally without changes which may occur due to being self-conscious of the camera. Calculations may occur within the controller or on a remote server to which data is transmitted.
