Correct answer: IEEE 802.1X

IEEE 802.1X is a port-based network access control (PNAC) standard. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. When a camera supporting 802.1X connects to a configured switch port, it must authenticate with a central server (like RADIUS) before the switch grants it access to the network, preventing unauthorized device connections.

Correct answer: False

This statement is false. Zipstream does not remove entire frames. Instead, it analyzes the scene to identify areas of interest (like moving people) and static background areas. It then applies higher compression to the static background areas while preserving high detail in the areas of interest. Dynamic GOP adjusts the frequency of I-frames based on motion, but it does not remove frames from the stream.

Correct answer: Electronic Image Stabilization (EIS)

Electronic Image Stabilization (EIS) is designed to reduce the visible effects of vibration in a video stream. It works by using the image sensor to create a slightly larger image than the final output, allowing the processor to shift the active area to counteract camera shake. This is the ideal solution for installations on poles, bridges, or other structures prone to vibration.

Correct answers: Forensic WDR; Lightfinder

Forensic WDR (Wide Dynamic Range) is essential for handling scenes with both very bright and very dark areas, such as a backlit entrance. It captures multiple exposures and combines them to produce a clear image where details are visible in both the bright exterior and the darker interior.

Lightfinder technology provides high-quality color video in near-darkness. This is critical for capturing identifiable details at night when ambient light is low, which is a common condition at store entrances after business hours.

Correct answer: A network switch that supports IGMP Snooping

IGMP (Internet Group Management Protocol) Snooping is a crucial feature for managing multicast traffic. A managed switch with IGMP Snooping listens to the IGMP conversations between hosts and routers. It learns which switch ports are connected to devices that have requested to join a specific multicast group. The switch then forwards multicast traffic only to those specific ports, preventing it from being broadcast to all ports and flooding the network.

Correct answer: A telephoto lens (e.g., 10mm or greater) will be required.

To achieve a high pixel density like 250 px/m at a distance of 20 meters, a narrow field of view is needed. This requires a lens with a long focal length, known as a telephoto lens. A wide-angle lens would provide a much lower pixel density at that distance, suitable for overview but not identification. The Axis Lens Calculator or manual formulas would confirm that a focal length of 10mm or more is necessary.

Correct answer: To manage image processing, video compression, and analytics.

The ARTPEC (Axis Real Time Picture Encoder) SoC is the specialized processor at the core of an Axis camera. It is responsible for a wide range of critical functions, including image processing (like WDR and Lightfinder), video encoding/compression (H.264/H.265), and running on-camera analytics applications. It is essentially the 'brain' of the camera.

Correct answer: AXIS Design Tool

AXIS Design Tool is a comprehensive software application that allows users to find the right cameras, place them on imported maps or floor plans, visualize coverage areas, estimate bandwidth and storage, and generate a complete bill of materials including all necessary accessories. It is the primary tool for creating detailed project designs and quotations.

Correct answer: The camera is experiencing an IR focus shift and was not focused correctly.

This phenomenon is known as IR focus shift or chromatic aberration. Visible light and infrared light have different wavelengths and focus at slightly different points. If the camera was focused during the day (using visible light), the focus can shift and become blurry when the IR illuminators turn on at night. Cameras with IR-corrected lenses minimize this, but the best practice for installation is to perform the final focus adjustment at night with the IR on, or use the camera's built-in focus assistant which accounts for this.

Correct answers: Signed Firmware; Secure Boot

Signed firmware ensures that only firmware cryptographically signed by Axis can be installed on the device. The camera verifies this signature before applying any update, preventing the installation of unauthorized or malicious firmware.

Secure Boot is a process that verifies the digital signature of the camera's firmware every time it starts up. This ensures that the firmware has not been compromised or altered since it was signed by Axis, preventing the device from booting with tampered code.
