The following options are available for overlays and masks:

Uploaded image as overlay is a text and/or a static image superimposed over the video image, for extra 

information.

To upload an overlay image to the camera:

1. Select the type of overlay to use in Overlay/Mask Type.
2. In the field Upload own image, click the Browse button and locate the image file on your computer or 

server. 

3. Click the Upload button and follow the on-screen instructions.

To use an already uploaded image:

1. Select an uploaded image from the Use image drop-down list.
2. Place the image at the required location by entering the x and y coordinates.
3. Click Save.

There are a number of limitations when using overlay images, such as the size and positioning of images. Please 

refer to the online help for more information.

Configurable areas as privacy mask are configurable areas of solid color that can be used to block out certain 

parts of the video image.

Make sure to set privacy masks while camera is set for full resolution to ensure full coverage of sensitive area.

This page contains settings for fine-tuning the video image. These include the color level, brightness, sharpness 

and exposure control. DC-Iris should always be enabled, except when focusing, or when using a non-DC-Iris 

lens.

Please see the online help for further information on these settings. 

Low Light Behavior
Exposure priority - These settings define the balance between possible motion blur, noise and frame rate. 

Prioritize Image Quality to lower noise may reduce frame rate while increasing exposure time and thereby 

motion blur. A prioritized frame rate limits the exposure time in order to allow for full frame rate. This may raise 

the gain factor, creating possible noise or darker exposure.
