Event-oriented multi-channel video backup apparatus and method, and network surveillance camera system including the same

An event-oriented multi-channel video backup method, comprising:

• capturing, by using a plurality of cameras, a plurality of surveillance areas to acquire video information for the plurality of surveillance areas;
• transmitting the video information for each of the plurality of surveillance areas through a corresponding one of multiple channels;
• receiving the video information from the plurality of cameras and performing a video search on the video information received through the multiple channels;
• backing up channel-wise video information generated according to a result of the video search;
• and
• storing and playing back the backed-up information,
• wherein the backing up the channel-wise video information comprises backing up metadata included in the video information for each of the plurality of surveillance areas, and the playing back the backed-up information is performed in an event-oriented and channel-wise manner based on the backed-up metadata,
• the method further comprising:
• obtaining still images containing detected objects by cropping videos from the plurality of cameras,
• wherein the received video information includes both the videos and the still images cropped from the videos and the received metadata includes time information when the objects are detected, and a chronological order or the same time at which at least two still images are played is determined based on the time information,
• the method further comprising:
• when a user selects at least two still images from the still images and the chronological order is determined based on the time information, listing the selected at least two still images in the chronological order in a section of a screen and playing the videos corresponding to the selected at least two still images in the chronological order in another section of the screen.

A video backup device comprising:

• an event-oriented channel-wise video backup file, generated according to a search result performed on channel-wise video information received from a surveillance camera;
• and
• a video playback software player configured to play back an event-based video selected by combining one or more pieces of information included in the event-oriented channel-wise video backup file,
• wherein the one or more pieces of information comprise a still image and metadata corresponding to the channel-wise video information,
• wherein still images containing detected objects are obtained by cropping videos from the surveillance camera,
• wherein the received video information includes both the videos and the still images cropped from the videos and the metadata includes time information when the objects are detected, and a chronological order or the same time at which at least two still images are played is determined based on the time information, and
• wherein, when a user selects at least two still images from the still images and the chronological order is determined based on the time information, the selected at least two still images are listed in the chronological order in a section of a screen and the videos corresponding to the selected at least two still images are played in the chronological order in another section of the screen.
