Monitoring apparatus and system

A monitoring system comprising:

• a camera configured to capture an image;
• at least one sensor configured to generate an event signal in response to detecting at least one of various types of events;
• and
• a monitoring device configured to communicate with the camera and the at least one sensor, the monitoring device comprising:
• a communication unit configured to receive the image from the camera and the event signal from the at least one sensor;
• a screen unit configured to display the image;
• and
• a control unit configured to control operation of the communication unit and the screen unit,
• wherein the monitoring device is configured to mark one or more target monitoring areas on the image,
• wherein the control unit is configured to detect an event related to a target monitoring area based on the event signal, and count a number of events that occurred in the target monitoring area, and
• wherein the screen unit is configured to numerically display the counted number of events in the target monitoring area.

A monitoring system comprising:

• a camera configured to capture an image;
• and
• a monitoring device configured to communicate with the camera, the monitoring device comprising:
• a communication unit configured to receive the image from the camera;
• a screen unit configured to display the image;
• and
• a control unit configured to control operation of the communication unit and the screen unit,
• wherein the control unit is configured to detect the occurrence of an event in a region of interest (ROI) in response to the ROI being defined in the image, and
• wherein the screen unit is configured to mark one or more of the ROIs on the image,
• wherein, in response to the occurrence of an event being detected in the ROI, the control unit is configured to count a number of events that occurred, and
• wherein the screen unit is configured to numerically display the counted number of events in the ROI.
