Abstract

An apparatus is provided for monitoring a person. The apparatus is configured for identifying one or more undesirable conditions, by analyzing data from a sensor unit associated with the person'"'"'s bed, the data being indicative of the person'"'"'s presence in or absence from the bed. Upon identification of at least one undesirable condition, the apparatus emits a local alarm and transmits an alert signal to a remote apparatus, which is configured for notifying one or more responders about the undesirable condition. If one or more responders responds to the notification, or if the apparatus is reset locally, the local alarm is stopped.
