Overlay/Mask Settings

Overlay/Mask Type
The following options are available for overlays and masks: 

• Uploaded image as overlay
• Configurable areas as privacy mask

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 Upload own image field, 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 while 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.

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

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

non-DC-Iris lens.

Use backlight compensation - When the image background is too bright, or the subject too dark, 

backlight compensation makes the subject appear clearer.

Please see the online help 

 for further information on these settings. 

Low Light Behavior
Low light conditions can reduce image quality and increase bandwidth usage. The Low Light Behavior settings 

define the balance between image quality and frame rate. During low light conditions, experiment with the 

settings Exposure priority, Max exposure time and Max gain until you achieve an acceptable image quality at 

the required frame rate. 

Exposure priority defines the balance between image quality and the frame rate. Higher image quality may 

reduce frame rate and increase motion blur. A prioritized frame rate may instead increase image noise. 

The height and width of the overlay image in 
pixels must be exactly divisible by 4.

The height and width of the overlay image in 
pixels must be exactly divisible by 16.
