ANVE Exam Dumps - Axis Communications Certifications Questions and Answers

PTZ cameras use lasers to measure the distance to the target, which allows for quick and accurate focusing. The laser range finder determines the precise distance between the camera and the subject, enabling the camera to adjust its focus optimally. This technology ensures that the camera can focus rapidly and accurately, even in challenging lighting conditions or when the target is moving. Axis Communications' technical specifications for PTZ cameras confirm that laser technology is employed to enhance focus performance by providing target distance information.

Variable bitrate (VBR) is a video encoding method that adjusts the bitrate according to the complexity of the video scene. The primary advantage of VBR is that it maintains image quality, even in high-motion scenes, by allocating more bitrate when needed and reducing it during simpler scenes. This ensures consistent image quality while optimizing the use of bandwidth. Axis Communications’ documentation on video compression and bitrate management confirms the benefits of VBR in maintaining image quality.

The maximum distance from a midspan to a camera requiring PoE+ (25.5 W) is 100 meters (328 feet). This distance limitation is due to the standard Ethernet cable length limit, ensuring effective power delivery and data transmission over the network.

A deep learning processing unit (DLPU) in a camera is used to provide AI capability on the edge. This enables the camera to perform complex analytical tasks, such as object detection, classification, and behavior analysis, directly within the camera itself without the need for external processing. This approach reduces latency and bandwidth usage while enhancing the camera’s ability to make real-time decisions. Axis Communications' product information on cameras with DLPU highlights this capability.

When an Axis camera is not behaving as expected, the maintenance functions available include "Camera restore" and "Factory default." The "Camera restore" function allows the user to reset the camera settings without affecting the network settings, while the "Factory default" function resets all settings to the original factory settings, including network settings. These functions help in troubleshooting and restoring normal operation of the camera. References: Axis Communications product manuals and support documentation.

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.

The corridor format is particularly useful for scenes such as the one depicted because it optimizes the camera's field of view for narrow, vertical areas. Traditional horizontal formats waste much of the frame on walls or empty spaces when monitoring hallways, staircases, or aisles. By rotating the camera 90 degrees and using the corridor format, you maximize the vertical field of view, allowing for better coverage and more effective surveillance in such environments. Axis Communications documents and product guides frequently highlight this advantage for corridor format applications.

Fixed box cameras typically use a CS-mount lens, which allows for easy installation and flexibility in changing lenses to meet different surveillance needs. The CS-mount standard is widely used in the security industry and provides compatibility with a variety of lens types. Axis Communications' fixed box cameras often feature CS-mount lenses, as detailed in their product specifications and installation guides.

AXIS M3057-PLVE MkII and AXIS P1378-LE both have built-in IR LED illumination. This feature is crucial for enhancing visibility in low-light conditions or complete darkness, making them suitable for various surveillance applications. The built-in IR LEDs ensure that these cameras can provide clear images even in challenging lighting environments.References: AXIS M3057-PLVE MkII, AXIS P1378-LE

A decoder allows for displaying digital live video on a monitor. Axis decoders convert digital video streams from network cameras into standard video signals that can be displayed on monitors. This is particularly useful in surveillance setups where live monitoring on standard displays is required. Axis offers various decoders designed for seamless integration with their camera systems, as detailed in their product documentation and solution guides.
