Privacy Mask

Privacy masks allow you to mask areas in an image that are prohibited for the viewer. A 3D mask, covers the area regardless of the camera’s angle or zoom position.

To set up a privacy mask:

1.Go to Setup > Video & Image > Privacy Mask and click on the Add button.

2.Move the camera’s view so that the area to be masked is at the center of the image.

3.Use zoom or change the Width and Height values to adjust size of the masked area.

4.Click Save.

Advanced Camera Settings

To optimize the lighting settings according to your requirements, modify the following settings under Lighting Conditions:

•Color level, Brightness and Sharpness- Find the level that best suits your image needs by testing.

•Exposure control - this setting is used to adapt to the amount/type of light being used. Allow slow shutter can be enabled/disabled when the exposure control is set to Automatic.

•Exposure area-This setting determines which part of the image will be used to calculate the exposure.

•IR cut filter - when the IR cut filter is set to OFF, the camera will be able to ‘see’ infrared light, e.g. at night, thus making the image clearer. The image is shown in black & white when the IR cut filter is off.

Note: If set to Auto, the camera will automatically switch between IR cut filter ON and OFF, according to the current lighting conditions. This is only possible when the iris is set to Auto Iris, and the exposure control is set to Automatic.

•Wide dynamic range - Corrects the exposure when the contrast is extreme
