Axis Communications 243Q Blade Manual Do Utilizador

Sometimes the image size may be large due to low light or complex scenery. Adjusting the 

Maximum frame size is a good way of controlling the bandwidth and storage used by the 

MJPEG video stream in these situations. Defining the frame size as Unlimited will provide 

consistently good image quality at the expense of increased bandwidth and storage usage 

during low light. Limiting the frame size helps optimize bandwidth and storage usage, but 

gives poor image quality. To prevent increased bandwidth and storage usage, the 

maximum frame size should be set to an optimal amount.

Overlay/Mask Settings
When using an image overlay, 

select the Overlay/Mask Type from 

the following options: 

• Uploaded image as overlay - 

usually used to provide extra 

information in the video image.

• Configurable areas as privacy 

masks - up to three black areas 

are used to conceal parts of the 

video image.

The difference between an overlay 

and a privacy mask is that a 

privacy mask cannot be bypassed by accessing the video stream with the help of the AXIS 

HTTP API, whereas an overlay can.

Selecting the overlay/mask type will display further settings available for the selected type. 

See the online help for further information.

1. Select Uploaded image as overlay in the Overlay/Mask Type drop-down list. 

New options appear.

2. Click the Browse button by the Upload own image field and locate the image file 

on your computer or server.

able resolution of the product.
