View area
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.
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.
Privacy masks
You'll see the privacy mask on all snapshots, recorded video, and live streams.
You can use the VAPIX® application programming interface (API) to turn off the privacy masks.
Important
If you use multiple privacy masks it may affect the product's performance.
Note
If you view the video stream over HDMI and restart the product, the privacy masks will disappear. To show the privacy
masks again, restart the video stream.
Overlays
Note
Overlays are not included in the video stream when using SIP calls.
Note
Image and text overlay will not be displayed on video stream over HDMI.
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration. You can add either text or an image.
Pan, tilt, and zoom (PTZ)
Guard tours
A guard tour displays the video stream from different preset positions either in a predetermined or random order, and for configurable
periods of time. Once started, a guard tour continues to run until stopped, even when there are no clients (web browsers) viewing the
images.
