Abstract: A plurality of self-contained remote environmental data-monitor-control units communicate with a central collection point, including transmitting and receiving data, control signals, program parameters and alert signals. The central collection point includes a web page interface allowing end users to view real-time, current status as well as trended data in textual or graphical form. The central collection point processes and forwards alert signals received from a remote environmental data-monitor-control unit or a third-party monitoring system to an alert notification system which can accept alert signals via email, page, and direct point-to-point communication, processes the alert signal to verify validity and eliminate redundant signals, and notifies one or more pre-selected recipients of the condition which caused the alert via confirmable, person-to-person notification.
