A view area is a cropped part of the full view. You can stream and store view areas instead of the full view to minimize bandwidth

and storage needs. If you enable PTZ for a view area, you can pan, tilt and zoom within it. By using view areas you can remove parts

of the full view, for example, the sky.

When you set up a view area, we recommend you to set the video stream resolution to the same size as or smaller than the view area

size. If you set the video stream resolution larger than the view area size it implies digitally scaled up video after sensor capture,

which requires more bandwidth without adding image information.

A capture mode consists of a resolution and the corresponding frame rate available in the product. The capture mode setting

affects the camera's field of view and aspect ratio.

The lower resolution capture mode is cropped out from the highest resolution.

The image shows how the field of view and aspect ratio can change between two different capture modes.

Which capture mode to choose depends on the requirements of frame rate and resolution for the specific surveillance setup. For

specifications about available capture modes, see the product's datasheet at axis.com.

A privacy mask is a user-defined area that prevents users from viewing a part of the monitored area. In the video stream, privacy

masks appear as blocks of solid color.

A privacy mask is a user-defined area that covers a part of the monitored area. In the video stream, privacy masks appear either as

blocks of solid color or with a mosaic pattern.

You'll see the privacy mask on all snapshots, recorded video, and live streams.

You can use the VAPIX® application programming interface (API) to hide the privacy masks.

Important

If you use multiple privacy masks it may affect the product's performance.

You can create several privacy masks. The maximum number of masks depends on the complexity of all the masks combined. The

more anchor points in each mask, the fewer masks you can create. Each mask can have 3 to 10 anchor points.
