The Search tool allows you to search recorded video for motion or alarms in specified areas of interest. Symphony will search based on your criteria and create a mini movie and thumbnails showing the results. For example, you may search for all activity around a car for the last 24 hours. Symphony will create a video containing only activity that occurred in an area of an image designated by you. The result may be a five minute movie, depending on how much activity was found.
A minimum of 2 GB of hard drive space is required on the drive where the search is performed. |
1. From the toolbar, click the Search button. The Search dialog box opens.
2. From the Analytics Engines list, select the engine. Depending on the analytics engine you choose, you can mark the area of interest for searching or select a class of objects to search for such as people or vehicles. Each engine has different search options that you can use.
Some options might be:
• Using the displayed image from the video, you define the area in blue (a mask) where objects in motion should be detected.
• Select the Erase option to erase the blue mask.
• Select the Draw option to draw the blue mask.
• The Size slider adjusts the pen thickness.
• Alternatively, digital fences can be used as the search criteria. Select Any fence to draw a digital fences. Selecting All fences denotes that the object must pass through all fence lines to result in resulting search video.
• Select the Class of object you wish to search for, such as People, Vehicles or Unknown objects (unknown objects are objects that were tracked but were not classified as people or vehicles).
• Select the Behavior to filter by, such as loitering.
3. Specify your search From and To dates. For more advanced settings, click the Advanced button.
• One Time Search - The search will be performed only once using the date range you selected.
• Specified Interval Search - You can specify to search between a date and time range. For example, between July 26 and July 30, but only between 6:38pm and 7:38pm.
• Recurring Search - Allows you to specify a search that Symphony will continuously perform until you end it. For example, between 18:00 and 8:00 each day. This option may be useful if you want automated searches done at specific times for review.
• Title - A user defined tile for the search can be defined.
• Email address - To notify a user the search is complete.
• Seconds before clip and Seconds after clip - Can be modified by entering a numeric value that represents the seconds before or after the event Symphony should begin to play the resulting video.
• Everything (green, yellow, red) - Will not filter any video. The resulting movie will include all frames between the From and To search times. (Green - no relevant foreground activity; yellow, indicates activity; red - a rule was broken.)
• Any Movement - Symphony will search for all activity between a specific date and time.
• Alarms Only - Allows you to select the specific events to search for as defined by the Rules.
• Events (group area) - Allows you to combine different search events in order to further filter the results. For example, you can search for people loitering AND cars parking within 60 seconds, and only these combined events would be displayed in the search results.
