To calculate the rising and setting of the sun for video units, or to plot a map for
LPR units, you can set the latitude and longitude of that entity.
What you should know
The geographical location (latitude, longitude) of an entity has two different uses:
- The geographical location of video units is used to automatically calculate the time
when the sun rises and sets on a given date. This is helpful if you want the system to
only record video during the daytime (for cameras that are placed outside), or adjust
the brightness of a camera based on the time of day.
- The geographical location of fixed LPR units without a GPS receiver is
used to plot the LPR events (reads and hits) associated with
the LPR unit on the map in Security
Desk.
To set the geographical location of an entity:
-
In the Location tab of an entity, click View on
map.
-
Navigate to the location of your entity on the map.
You can click and drag to zoom in, zoom out, and pan.
-
Click Select in the map window.
The cursor changes to a cross.
-
Click on the desired location on the map.
A pushpin appears on the map.
-
Click OK.
The latitude and longitude fields display the coordinates of the location you clicked on
the map.
