• generating a log icon which includes the thumbnail image and event information corresponding to each of the event;
• and
• displaying, on a timeline, a log list including the log icon corresponding to each of the event;
• and
• in response to the log icon being selected, displaying, within the selected icon, an activated event image corresponding to the selected log icon in a reproducible state, and at least one of a speaker image indicating an audio event and a human image indicating a motion sensing event, while the plurality of images are being displayed in real time,
• wherein at least one of the plurality of images is a real-time video image of a monitored area that is monitored by the surveillance camera, and the activated event image is a previously recorded video image of the same monitored area, and
• wherein the real-time video image of the monitored area is continuously played while the previously recorded video image of the same monitored area is selected from the log list and played.

A monitoring system comprising:

• a surveillance camera that monitors an area;
• a processor configured to detect occurrence of at least one event from a plurality of images, generate, from the plurality of images, a thumbnail image and an event image at a time of the event occurrence, and generate a first log icon which includes the thumbnail image and information about the event;
• and
• a display configured to display a log list including a plurality of log icons on a timeline, the plurality of log icons including the first log icon,
• wherein the processor is further configured, in response to the first log icon being selected, control the display to display, within the selected first log icon, an event image corresponding to the selected first log icon in a reproducible state, and at least one of a speaker image indicating an audio event and a human image indicating a motion sensing event, while the plurality of images are being displayed in real time,
• at least one of the plurality of images is a real-time video image of the monitored area, and the event image is a previously recorded video image of the same monitored area, and
• wherein the real-time video image of the monitored area is continuously played while the previously recorded video image of the same monitored area is selected from the log list and laved.
