By default, the SharpV is configured to automatically adjust exposure settings for changing light conditions when capturing license plate reads. Alternatively, if you are installing a SharpV camera indoors, for example, in an underground parking lot, you can define fixed values for the camera's iris, shutter time, and gain settings. Doing this can result in more consistent exposure for LPR and context images.
IMPORTANT: Modifying the SharpV exposure settings can greatly impact LPR performance. Vanity plates, or plates that are damaged or dirty can have different reflective properties. Improving the exposure using a stationary test plate can result in reduced LPR performance on every-day traffic which includes plates with a wide range of reflective properties. You must test the system after modifying these settings.
