Embodiments of the invention provide apparatuses, methods, and systems utilizing one or more commonly available sensors to actively monitor one or more particular environments based on data received from one or more physical sensors and virtual sensors (e.g., physical sensors “fused” to provide more useful information) regarding one or more attributes of the environments being monitored. This sensor data may then be utilized to describe the activity/non-activity of individual(s) present in the monitored environments. Aspects of the invention further determine behavioral patterns related to activity of the monitored environments and evaluates the received data to determine one or more deviations from one or more behavioral patterns, and then, based on the evaluating, selectively indicating an alert condition indicative of the determined one or more deviations.
