4.7 Frame De-Interlacing
Frame De-interlacing applies only to DVR480 Series DVRs running VIGIL Server version 2.03.0000 and higher,
recording at resolution 704x480.
When paused in the Playback window, use the Frame De-interlacing feature to toggle between F -
Full Field, AF – A Field and BF – B Field. Click on the F button to toggle between frame types or use
the drop-down arrow menu to select the frame type.
4.8 Authenticating Recorded Video
VIGIL Server embeds a security key in recorded footage for each video frame. These keys can be easily
checked to verify that the footage is authentic and has not been tampered with.
Begins the authentication process; a window opens displaying the progress. Depending on the
length and location of the video footage, Authentication may take several minutes to complete. You
can cancel the authentication at any time by clicking Cancel. Any frames that were processed prior
to cancelling have been authenticated. If the video is authentic, the Authentication Complete
message will be displayed.
If the video has been tampered with, the authentication will
halt at the first damaged frame and provide an error
message with the problem frame number. If Real-Time Authentication (in DVR Settings | Search tab)
is enabled, during playback a large red X is displayed over
the frame if the footage does not pass authentication.
