Privacy Mask
The Privacy Mask function aims to avoid any intrusive monitoring. Users can adjust the camera view
position using the joystick, and adjust the mask size and area via the direction keys on the control
keyboard. When setting a mask, it is suggested to set it at least
twice bigger
(height and width) than the
masked object. The PTZ Dome Camera will assume the center of the selected view as an starting
point, and the joystick will be locked as users enter the SET MASK menu (mentioned later). Refer to
the following description for setting privacy masks.
NOTE:
The Image Flip function and the Image Inverse function will be disabled automatically while the
Privacy Mask function is enabled.
The available area for setting a privacy mask is restricted with a tilt angle of 70 degrees. Maximum 8
masks can be displayed in one scene. All the settings are described as the following:
