The following search methods are introduced:

•Calendar – pan temporal time line can zoom in on selected date to make search easier (see "Using Calendar").

•Smart Motion Search – select a region on video and allow for the application to automatically refine the archive and highlight the fragments that involved motion. See "Performing Smart Motion Search".

•Thumbnail Navigation – small previews are displayed on top of the Time Line to help locate a particular scene. See "Using Thumbnails for Better Navigation".

•Preview Search – select a region and allow for the application to provide videos that represent a time period based on time stamps. See "Preview Search".
