AutoVu™ SharpOS 13.2.1 includes the following known limitations.
|Issue||First reported in||Hardware affected||Description|
|2523552||13.1.1||SharpZ3||If the background vegetation is covered by a shade, the color of the vegetation might appear pink in context images.|
|2490592||13.1 GA||SharpZ3||Context images and wheel images taken while the patrol vehicle is traveling
faster than 40 km/h (25 mph) might be slightly distorted. For example, vehicle tires
might appear slightly oval in shape.
Workaround: To reduce distortion, drive the patrol vehicle at a maximum of 40 km/h (25 mph).
|2489708||13.1 GA||SharpZ3||When a SharpZ3 system is configured to use DHCP in the page of the Sharp Portal, the setting applies to the ALPR module, but does not apply to expansion modules. Expansion modules connected to the base unit always use static IP addresses as defined on the Network page.|
|If the sun is low and behind the Sharp camera, the reflection of the sun on the target vehicle can overexpose the context image.|
|2354306||12.8 SR1||SharpV||When the main server is rebooted, a Sharp unit might not reconnect to the main or
Workaround: Update the Sharp Platform to the latest package available on GTAP.
|2354385||12.8 SR1||SharpV||If you change the certificate of a SharpV when the ALPR Manager role is down, the
SharpV might not be able to reconnect
once the ALPR Manager role is up.
Workaround: Add the SharpV unit again in Config Tool. Select SharpV Certificate and wait for the unit to reboot.
|You cannot downgrade a Sharp unit to an earlier version of SharpOS.|
|2239258||12.8 GA||SharpV||When the SharpV is configured to monitor dual lanes, the virtual loop, speed estimation, and region of interest features are not available.|
|2237601||12.8 GA||SharpV||When using the dual lane feature in conjunction with the Single read on trigger reading mode, two reads are generated every time the camera is triggered. If a vehicle is present in only one lane, the system generates one ALPR read and one NOPLATE read.|
|When the Accept remote reboot requests checkbox is cleared in the Sharp Portal, it is still possible to reboot the unit by right-clicking it in the Config Tool area view entity tree and selecting .|
|2236319||12.8 GA||SharpV||If you change the video encoding configured for a SharpV while the camera is already added on the Archiver, the video stream connection is lost and must be reconfigured to connect with the correct encoding.|
|2224894||12.8 GA||SharpV||When the Free-Flow read strategy is enabled on a SharpV, the speed estimation feature is not available.|
|2195726||12.7 GA||SharpV||The Virtual loop feature can sometimes generate NOPLATE events when
parked cars are in the field of view.
Workaround: To reduce false NOPLATE events, adjust the zoom level of the ALPR and context cameras so that the context camera field of view is about double the width of the ALPR camera field of view.
|2149700||12.7 GA||SharpV||Using the Optimize for static image background feature is not recommended if only a small part of the image background is static, for example, if many moving trees are visible. It is not recommended to use this feature in conjunction with Virtual Loop when vehicles are traveling at speed above 50 km/h (30 MPH).|
|When updating the Sharp unit using Internet Explorer, the upgrade might fail if the Windows feature Enable 64-bit processes for Enhanced Protected Mode is not enabled.|
|2136538||12.7 GA||SharpV||Following an upgrade to SharpOS 12.7 or higher, the browser is refreshed and points to https://<SharpV IP address>:443. If the network topology uses a NAT, the browser will not be redirected to the Sharp Portal unless port forwarding has been configured for access to the Sharp Portal.|
|2030186||12.7 GA||SharpV||When a SharpV is enrolled under the
ALPR Manager using the LPM protocol, if you then modify the configuration to use the
Center (legacy) extension, a
second SharpV entity is added to the ALPR
Workaround: To ensure that the reads that were made using the LPM protocol are still accessible, merge the reads from the two entities using the Unit replacement tool in Config Tool.
|2025741||12.7 GA||SharpV||When a SharpV is configured to use the Security Center (legacy) extension with the This unit manages the connection to Security Center feature enabled, if the main server fails, the unit cannot connect to the failover server.|
|1959475||12.7 GA||SharpV||After upgrading a SharpV to use the LPM protocol, the auto-generated self-signed certificate that is included with the SharpV is not automatically installed on the server machine.|
|1951944||12.7 GA||SharpV||If a SharpV is added to the ALPR Manager using the LPM protocol and the extension is then changed to Security Center (legacy), a duplicate offline SharpV is added to the ALPR Manager so that locally-stored plate reads can be retrieved.|
|945150||12.3 GA||SharpV||When configuring the virtual loop, the zoom level of the ALPR and context cameras must be adjusted so that the context camera field of view is more than the double of the width of the ALPR camera field of view.|
|944854||12.3 GA||SharpV||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||12.3 GA||SharpV||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||12.3 GA||SharpV||If the ALPR 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||12.2 GA||SharpV||When using the Optimize for static image background feature, the system can sometimes read plates in the image background after a vehicle or pedestrian passes in front of the camera.|
|741365||12.1 GA||SharpV||When updating a Sharp from the
Sharp Portal using the Web Updater tool,
the upload files might fail if you are using Internet Explorer 11.
Workaround: If you are using Internet Explorer to access the Sharp Portal, open the browser's Internet Options configuration page, select the Advanced tab, turn on Enable 64-bit processes for Enhanced Protection Mode, and the restart the computer.
