Limitations are software or hardware issues that cannot be fixed. For certain limitations, workarounds are documented.
AutoVu™ SharpOS 12.5 GA includes the following limitations:
|945150||When configuring the virtual loop, the zoom level of the LPR and context cameras must be adjusted so that the context camera field of view is more than double the width of the LPR camera field of view.|
|944854||The Speed estimation feature uses the width of the license plate to calculate the vehicle's speed. When this feature is used in regions where there are multiple license plate widths, for example, if trucks use different sized plates than cars, speed estimation can be inaccurate.|
|942672||The speed estimation feature is less accurate in countries where the license plate dimensions are not uniform. Speed estimation is also less accurate because some plate features (for example, logos) can make the plate appear smaller than it is.|
|900724||If the LPR camera fails to capture a vehicle’s license plate and the vehicle is then detected by the virtual loop, a NOPLATE event is only generated when the vehicle leaves the camera's field of view. In the case where the vehicle is still within the field of view when it exits the parking lot, the parking attendant is not notified of the NOPLATE event until after the vehicle has left the parking lot.|
|781714||When using the Optimize for fixed installation feature, the system can sometimes read plates in the image background after a vehicle or pedestrian passes in front of the camera.|
|741365||When updating a SharpV from the web portal using the Web Updater tool, the upload
files might fail if you are using Internet Explorer 11.
Workaround: Close the Internet Explorer task from your Task Manager, and then start a new Internet Explorer session to the SharpV web portal. Perform the update again.
