Abstract: Provided is a system used in various facilities, which enables every specific event as a sign of an accident to be detected without missing to ensure transmission of an alert message at a proper time, thereby preventing accidents from occurring. The system includes cameras for capturing images of a monitoring area, and a monitoring server for controlling transmission of an alert message based on the images, wherein the monitoring server is configured to: set a sensing area around an entrance to a risky point (escalator entrance) and a notifying area closer to the risky point than the sensing area; sense a person in the sensing area and detect a specific event associated with the person based on images captured by each camera; and, when the sensed person enters the notifying area, transmits an alert message corresponding to the specific event associated with the person.
