20AXIS 241QA/AXIS 241SA - Video & image settings

The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of viewing client to use.

Adjusting the maximum bit rate and setting it to variable or constant is a good way of controlling the bandwidth used by the MPEG-4 video stream.

MJPEG

Sometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control the bandwidth and storage used by the MJPEG video stream in these situations. Defining the frame size as Unlimited provides consistently good image quality at the expense of increased bandwidth and storage usage during low light. Limiting the frame size optimizes 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 value.

For more information on these advanced settings, please see the online help.

Quad stream settings

A Quad stream enables you to monitor all channels at the same time. Instead of having four Internet Explorer windows open, you can have just one window open with the Quad view. You can edit this view with the desired stream time, frame rate, and text overlay. These settings are the same as the Image Settings. See page 18.

Overlay/Mask settings

Overlay/Mask type

Overlay/Mask type allows you to place an overlay, or up to three privacy masks over the video image:

•Upload and place an image as an overlay - usually used to provide extra information in the video image.

•Place up to three configurable privacy masks to conceal dif- ferent areas of the video image.

Selecting the overlay/mask type from the menu will display further settings available for the selected type. See the online help for further information.

Note: A privacy mask cannot be bypassed, but an overlay image can be bypassed with the help of the VAPIX® API.

241SA specifications

Axis Communications, a leader in network video solutions, offers a diverse range of high-performance cameras designed to meet various security needs.
