The Kiddo Kidkeeper system, a wireless proximity alarm system, is designed to boost child safety by helping parents quickly locate wayward young ones and keep them within a pre-set “virtual fence”. It consists of a transmitter which is attached to the child and a receiver which is carried by the adult. The adult sets the maximum distance a child can wander to, if the child moves outside this area the Kiddo emits a warning sound and the transmitter shows a visual signal allowing the adult to retrieve the child quickly.
