The primary purpose of the accessory on this dome camera is to reduce the weather impact. This accessory, often referred to as a weather shield or rain guard, helps protect the camera lens from rain, snow, and other environmental elements, ensuring clear visibility and reducing the need for maintenance.

View areas enable multiview streaming by allowing users to stream different parts of the camera's field of view simultaneously. This includes the ability to stream both optically zoomed-in views and the full, normal views at the same time. This feature enhances monitoring flexibility and situational awareness by providing multiple perspectives from a single camera feed. Axis documentation on multiview streaming explains how view areas can be configured to deliver both zoomed and wide-angle views concurrently, facilitating comprehensive surveillance.

Deinterlacing in video encoding is used to eliminate the artifacts that occur when the two fields of an interlaced video frame capture different moments in time. These artifacts, known as tearing effects, can be particularly noticeable when there is motion in the scene. Deinterlacing processes the fields to produce a single frame, resulting in a smoother image with reduced tearing. [Reference: Axis Communications - Video Processing Techniques]

VAPIX® is Axis' proprietary API (Application Programming Interface) that enables integration and management of Axis network video products. It allows developers to access a wide range of functionalities, such as video streaming, event management, and configuration settings, specifically tailored to leverage the latest capabilities of Axis cameras. ONVIF (Open Network Video Interface Forum) is an industry standard that facilitates interoperability between IP-based security products regardless of manufacturer, supporting basic functionalities for video and audio streaming, PTZ control, and event handling but not exclusively tailored to the latest Axis camera features.
