By default, the Sharp is configured to automatically adjust exposure settings for
changing light conditions when capturing plates. If the Sharp is installed indoors with fixed
lighting conditions, you can disable the auto-exposure on the Live feed
page of the portal and manually adjust the exposure settings.
What you should know
- Any settings that are modified, are applied immediately and can be viewed in the
Video feed window.
- It is recommended to test your settings first with the plates closer to the camera,
and then the plates further from the camera. This ensures that your exposure settings
will be adequate regardless of whether a car is further or closer to the camera.
- It is recommended to keep the Gain at a low value. You should
start with the Gain at the default value and try to set the
exposure using the Shutter time.
Procedure
-
Log on to the Sharp portal in
Advanced mode.
-
Click the Live feed tab.
-
From the Camera drop-down list, select LPR camera
from the drop-down list to view its live feed.
NOTE: On a SharpX you can have more than one
camera set, therefore you will see LPR camera 2,
LPR camera 3, and so on.
-
Under Exposure settings, clear the
Auto-exposure checkbox.
-
With the plates closer to the Sharp camera, set the Gain
value to the minimum default value and adjust the Shutter time
until you are satisfied with the plate image.
-
With the plates further from the Sharp camera, check to see that the plate is not
too dark. If it is, increase the Shutter time.
-
(Optional) If you reach the maximum possible Shutter time
and you are still not satisfied with your plate image, increase the
Gain.
You can click Cancel at any time to cancel your
modifications.
-
When you are satisfied with the appearance of the plate images in the
Video feed window, click Save.
-
(Optional) Click Reset to default to reset the Sharp to use
the factory default exposure settings.
