Long-distance connections

This product supports fiber-optic cable installations through a media converter. Fiber-optic cable installations offer a number
of benefits such as:
• Long-distance connection
• High speed
• Long lifetime
• Large capacity of data transmission
• Electromagnetic interference immunity
Find out more about fiber-optic cable installations in the white paper "Long distance surveillance - Fiber-optic communication in
network video" at axis.com/learning/white-papers.
For information about how to install the media converter see the Installation Guide for this product.

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.

Remote focus and zoom

The remote focus and zoom functionality allows you to make focus and zoom adjustments to your camera from a computer. It is a
convenient way to ensure that the scene's focus, viewing angle and resolution are optimized without having to visit the camera's
installation location.

Privacy masks

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.
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.
Important
Set the zoom and focus before you create a privacy mask.
