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.
