A US start-up has developed a software programme that uses home-security systems to monitor an elderly person's daily activities, aiding them to live independently for as long as possible. Baltimore-based Concordia Systems has launched SentinalCare, which uses a mobile app to enable the person's relatives to track their welfare, receiving alerts if there is a problem, such as a fall.
