Navigation: Working with Nx Witness > Playback in Nx Witness > # Advanced Archive Search Tools |

Nx Witness provides many features that make archive search faster, more convenient, and fully intuitive. Since an archive may contain a significant volume of video data (taken over several months), it is crucial to minimize the time a user spends searching for a particular event.

The following search methods are available:

•Calendar – Timeline can be zoomed to a selected date (see "Using Calendar").

•Smart Motion Search – selects a region on video, refines the archive, and highlight fragments that include motion. See "Performing Smart Motion Search".

•Thumbnail Navigation – small previews are displayed on top of the Timeline to help locate a particular image or event. 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".

•Bookmarks – select a segment of footage from a single Camera and give it a name, description and assign tags. See "Using Bookmarks".
