Video Search - Query Instructions

The Query Builder form allows you to build dynamic queries to select specific video clips from the thousands available based on numerous criteria such as behavior, category of species, species, visibility, camera number, date, and time. The Query Builder also allows users to find specific video clips by filename so you can easily return to interesting clips once you know the clip's filename.

Please note that the Query Builder form finds videos that meet all of the criteria selected. Therefore, the more criteria you select, the narrower your results will be. However, being too specific can often result in zero videos being returned so it is best to only use a few broad criteria at first. Then, if you need to further restrict your results, hit the [back] button of your browser, add additional criteria, then run the query again.

Setting a control to "-All-" will eliminate the criteria from consideration. Therefore, "-All-" is the default setting for most controls.

Below are descriptions of the individual Query Builder form controls and how they are used.

Behavior

Choose from the predefined list of behaviors. Only a single behavior may be selected from this list.

Species Category

Choose from the predefined list of species categories. Only a single species category may be selected from this list.

Common Name and Species Name

Choose from the predefined list of common names or species names. Note that you should select either a common name or a species name but not both. Accidentially selecting both a common name and a species name that are not the same animal will always result in zero videos being returned.

Visibility

Choose from the predefined list of visibilities. Only a single visibility may be selected from this list. However, the query will always return videos that are at least the quality that you have selected. For example, if you choose a visibility of "2 (fair)" you will also get videos that have "1 (good)" quality.

Camera

Choose from the predefined list of cameras. Only a single camera may be selected from this list. In general, it is best to leave this set to -All-.

DateTime Range

Enter a beginning DateTime and an end DateTime to return only those video clips from that period. DateTime values must be enterred in the format YYYY-MM-DD HH:MM:SS where YYYY is the 4-digit year, MM is the 2-digit Month, DD is the 2-digit Day, and HH, MM, and SS are the the 2-digit Hour, Minutes, and Seconds respectively. Note that the time part (HH:MM:SS) may be omitted entirely if you are only interested in a date range.

To have the query ignore this criteria clear both boxes.

Month

To find videos from only certain months select one or more months from the list. This control allows multiple selections. To select a range of months, select the first month of interest and then hold down the [shift] key while clicking the last month of interest. For noncontiguous selections, you can hold the [control] key while clicking (for Windows) or hold the [option] key while clicking (for Mac).

Hour

To find videos from only certain hours select one or more hours from the list. This control allows multiple selections. To select a range of hours, select the first hour of interest and then hold down the [shift] key while clicking the last hour of interest. For noncontiguous selections, you can hold the [control] key while clicking (for Windows) or hold the [option] key while clicking (for Mac).

The hour list is in 24 hour format (i.e., 0 = 12:00 AM, 12 = 12:00 PM (Noon), and 23 = 11:00 PM). Also note that video clips are generally only available for daylight hours.

Filename

If you already know the name of a file that you would like to view, then you may type it into this control. This control also allows for powerful "wildcard" searching where the character "%" is used to represent 0 or more of any character, and the underscrore "_" character is used to represent exactly one of any character.

Our video filenames all have a standard format of cCYYYYMMDDHHNNSS.###.avi where C = camera number, YYYY = four-digit year, MM = two-digit month, DD = two-digit day, HH = two-digit hour, NN = two-digit minutes, and SS = two-digit seconds.

Limit Rows Returned

By default your query will only return the first 100 videos that meet the query criteria specified. This limit is in place to prevent users with slow Internet connections from accidentally requesting a very large results page that will take an unreasonably long time to download. You can change this default setting as needed using this control.
