A method and apparatus are disclosed for monitoring a location using vision-based technologies to recognize predefined assistance-invoking events. One or more image capture devices are focused on a given location. The captured images are processed to identify one or more predefined events and to initiate an appropriate response, such as sending assistance or recording the event for evidentiary purposes. A number of rules define various assistance-invoking events. Each rule contains one or more conditions that must be satisfied and a corresponding action-item that should be performed when the rule is satisfied. At least one of the conditions for each rule identifies a feature that must be detected in an image using vision-based techniques. An event monitoring process is also disclosed that analyzes the captured images to detect one or more assistance-invoking events defined by the event rules.
