Hardware-based compression cards (DVS and DVS2) support watermarks, which makes it possible to superimpose arbitrary text and the current date and time. Watermarks can be used to prove the authenticity of video and protect an archive from being replaced.
In the Text on video area, you can enter arbitrary text (for example, the name of the camera) and select a position. You can also superimpose the current date and time on an archive.
Tip
Note that when viewing a channel on the server, the watermarks will not be visible. Watermarks can be superimposed on video in an archive in our displayed when connecting to a channel over a network.
Warning
The Latin alphabet is used to display text over video; displaying text using the Cyrillic alphabet is not supported.
