Important Axis ANVE Exam Questions

Answer: A

Explanation:

To prevent reflections from built-in IR illuminators from degrading the image quality, an installer can adjust the camera's field of view. By repositioning the camera or slightly altering its angle, the installer can minimize the direct reflection of IR light back into the lens, which often causes glare and reduces image clarity. Axis installation guidelines recommend adjusting the camera's position to avoid reflective surfaces and ensure optimal use of IR illumination for clear, unobstructed images.

Answer: C

Explanation:

Routers use IP addresses to determine where to send data packets. IP addresses provide the unique identification needed for routing data across networks, enabling the router to direct packets to their correct destinations. This fundamental aspect of network communication is outlined in Axis Communications' documentation on network protocols and IP-based systems.

Answer: D

Explanation:

The background of the scene is slightly out of focus due to a shallow depth of field. Depth of field refers to the range of distance within a photo that appears acceptably sharp. A shallow depth of field results in a narrow focus area, causing objects outside this area to appear blurred. This can be influenced by the aperture setting of the lens, the focal length, and the distance to the subject. Axis documentation on camera setup and focus adjustments provides guidance on managing depth of field to ensure optimal image clarity.

Answer: D

Explanation:

The fisheye view from a 360 panoramic camera can be dewarped both on live video streams and stored video material. Dewarping is a process that corrects the distortion inherent in fisheye lenses to present a more natural-looking image. This feature is supported in Axis cameras and video management software, allowing users to view undistorted video in real-time and from recorded footage. Axis documentation confirms that dewarping functionality is available for both live and archived video streams.

Answer: D

Explanation:

The Sharpdome technology allows PTZ cameras to maintain a sharp image even when pointed above the horizon. This feature uses a specialized mechanical design and advanced image processing to ensure clear, undistorted images across the entire dome, including the critical area above the horizon. Axis Communications has integrated Sharpdome technology into several of their PTZ camera models, as explained in their product specifications and technical white papers.
