A system for monitoring an unsupervised worker is provided that includes a plurality of sensors and a base station provided at the monitored location, a service provider server located remotely from the monitored location and operated by a third party service provider, and a computing device associated with a subscriber to the system. At least a portion of the sensed data is sent to and stored by the service provider server so that a report based thereon may, at the request of the system subscriber, be selectively generated and provided to the system subscriber. The computing device is also adapted to generate configuration data for one or more of the sensors and transmit the configuration data to the service provider server. The configuration data is then sent to the base station and used to control the operation of the sensors.
