33. Sleep: Number of milliseconds that the LPR engine should “sleep” if no motion is
found in a frame. This should never be set to a value more than 1000 but can
greatly decrease CPU usage with a value in the 200 millisecond range. If
background segmentation is off, the engine never sleeps. Ideal setting is 200.
34. Draw Motion Rectangles: Checking this instructs the LPR console to draw (in
yellow rectangles) the motion that it sees during background segmentation. If
background segmentation is disabled, you are responsible for drawing up to 5
hot boxes in which the LPR Engine looks for valid plate images. In other words,
if background segmentation is enabled, the system “finds” it’s own hot boxes by
looking for motion in the images. If “Draw Motion Rectangles” is checked, the
screen will show the motion that is found. This setting has no impact on what is
stored in the database as is intended to be a diagnostic tool.
35. : This is used to load a static image to process in the engine and
examine results.
36. : Point this to a folder of jpgs and it will allow you to step through
them and test the read ability of the images that have been recorded.
37. : After an image is loaded with “Load Image”, this processes it once.
38. JPEG Quality: Determines the quality of the JPEG images stored in the ESM
database. This value ranges from 1 (lowest quality) – 100 (highest quality). Start
at 30 and see if the recorded data is visible by the human in the User GUI, the
goal here is to put a smaller file size in the User GUI for WAN optimization.
Typical values range from 40-60.
