Permanent events erasing from the reader

Solution:

The reader is equipped with non-volatile 32 000 event log memory. Downloading events from the reader with Patrol Master software does not mean these events are physically erased. Downloaded events remain in memory of the reader and are marked as "archive events". In case of need they can be read again using special command in Patrol Master: Events Log > Restore deleted events from the reader.

Events are erased permanently only in one case - when oldest events are overwritten by newest ones. In order to physically delete an events they must be overwritten by the next 32 000 events. Assuming event register every 5 seconds it would take approximately 45 hours to perform such procedure.
