● If the [OK] button is pressed upon entering an invalid value, a warning message will appear and the
entry will be denied. Press the [Cancel] button to restore the invalid entry to its previous value. When
you press the [Cancel] button, other entries that you changed will also be restored to their previous

transfer capabilities are exceeded, video may not be displayed on the [Tampering Detection] page.
When using the [Tampering Detection] page, disable the Built-in Viewer and other clients.
Note:

Detection may not be possible due to the installation conditions of the camera or the subject being shot.

cannot be used.
