Protecting recorded files
There are two methods to prevent recorded files from being inadvertently
overwritten or deleted off the HDD. We highly recommend that important
recorded events be protected from deletion. Recorded files can either be locked
or the HDD that the files reside on can be set to read only.
Locking and unlocking recorded files
Lock files to protect them against being overwritten or deleted.
To lock or unlock a recorded file:
1. In live view enter the video search window by pressing the Search button on
the front panel or remote control, and then enter Advanced Search.
— Or —
In live view right-click the mouse to display the pop-up menu and select
Advanced Search.

include the camera number, record type, file type, and start time and end
time.
