A system for monitoring a person comprises establishing a check-in period, wherein the system checks for a check-in from local devices, local to the person monitored during the check-in period. If no check-in is received during the check-in period, sending a message to a remote communication device, from a first user different than the monitored person. If no check-in is received from the first user, sending a message to additional remote communication devices stored in memory until a check-in is received or until all devices stored in memory are exhausted without a check-in. If a check-in is received from a local device or a remote communication device, stopping the check-in period and stopping sending messages to remote communication devices and waiting for the next scheduled check-in period to check for check-ins. |
