Privacy Controls
Masks On / Off
This is an override setting to turn masks completely On or Off. This will not clear
each individual masks settings, so when Off is sent they will disappear and then
re-appear with On, in the same positions.
Crosshair On / Off
This setting makes a crosshair appear on the video display centered on the middle
of the video. This can then be used to set individual mask pixels with the
appropriate command from below.
Show / Clear Mask Style
This setting provides a preview of the current mask style. This will only work if the
Crosshair is turned On. It will show a small privacy block to the right of the
crosshair center. If nothing appears, the mask may be clear, so use the Set Mask
Style to change to a visible setting. Once the required style has been selected;
press Clear Mask Style and Crosshair Off, to return to the normal state.
Mask / Clear Whole Screen
These functions will add or remove a privacy mask the size of the entire current
view. Moving the MIC in Pan or Tilt should then indicate the zone clearly. This
would most commonly be used in conjunction with zoom where a window can be
made full frame and then the whole thing masked as apposed to the method below
which may take significantly longer.
Mask / Clear Pixel
This is a more accurate way of creating privacy masks one pixel at a time. The
Pixel is created at the center of the image, or where the crosshair points if it is
visible.
Set Crosshair
This will create a pixel sized mask as with the function above, and will also bring
up the crosshair. Press again to remove the crosshair or use Crosshair Off.
Set Mask Type
If Crosshair and Mask Style are both turned On this function can be used to step
through each of the available mask types one at a time. This will not update all the
masks to the same type, only the ones that are created subsequent to the change.
Load Factory Defaults
Clears the current Privacy masks and resets the privacy card to the factory
defaults.
MIC Configuration
These options define the MIC's orientation, which defines how the masks track. for
Inverted MICs, the head would normally be rolled around through 180 degrees,
with Pan Reverse On to regain sensible control. However, with inverted IR MICs,
the head cannot be rotated around due to the IR Lamp arms, and therefore the
video must be inverted, and both controls reversed.
Basic Calibration
This sends a set of default commands to the MIC to initialize the privacy for an
upright MIC. This will not be perfect as each board needs fine individual calibration
but provides a good starting point.
Zoom Alignment
The zoom alignment buttons provide accurate calibration of the mask tracking.
This would normally be carried out by using a vertical line of mask on along a
known straight edge. If this line then moves as the MIC pans and tilts, it can be
corrected using the appropriate arrow. The labels indicate the current value in both
the Vertical and Horizontal planes, which will be incremented or decremented
dependant upon the direction pressed.
Direct Command
All privacy commands consist of 2 Hex bytes, a command byte and a data byte.
These perform all of the privacy functions available. To enter commands, enter the
2 bytes in Hex, into the boxes provided and press Send Command. Entering
random commands here may result in very odd results so please do not use
unless under specific instruction.
Save Current Settings
Once any calibration changes are made, this button should be pressed to save the
new values permanently.
