You can remove the data in an offload file from the ALPR Manager database.
What you should know
Patrollers and handheld devices offload to an ALPR Manager. The offloads are duplicated and stored in the ALPR Manager database. In the Inventory management task, the reads are associated with a parking facility, and they are marked as not yet part of an inventory.
If you delete an offload from the Offloads list, the reads are no longer linked to a parking facility. However, the data remains in the Security Center database as regular plate reads, and they can still be queried using the Reads task.
