Watermarking
You can overlay digital watermarking to authenticate images and protect them from
alterations. Watermarking on an image is only visible during playback of exported
video.
The recorder supports watermarking from TruVision cameras and encoders.
Use the playback application, Player, to reveal the watermarking on archived video.
Enable the Watermarking option in Player.
Hiding a camera image from view
There may be occasions when you want to control who can live view the camera
images on a local monitor, such as if there is a camera located in a changing room. The
recorder lets you select which camera (or cameras) is not displayed on the local
monitor unless the user is logged in and has permission to live view the camera. A
covert camera is not displayed on screen when no user is logged in. Instead a person
walking by sees a black screen with the Interlogix logo. See Figure 39 below.
Figure 39: Example of a covert camera image
To set up a camera for covert view:
1 From the menu toolbar, click Camera Management > Covert Camera.
2. Check which camera or cameras you want to be covert and click Apply.
