No. It cannot be upgraded the WV-SC588 from the firmware of WV-SC588
to the firmware of WV-SC588A.
WV-SC588A is the successor model of WV-SC588, but both of them are different cameras.
Therefore it is available the latest firmware of WV-SC588 in WV-SC588.
*In case it is upgraded the WV-SC588 from the firmware of WV-SC588
to the firmware of WV-SC588A by using
Panasonic Security System Configuration Tool (PSSCT),
upgrading operation is finished normally.
But after this, camera will not work well because the firmware is not updated correctly.
