Axis Communications Certifications ANVE Exam Dumps

Pixel density describes the number of pixels per meter (or foot) horizontally. This metric is crucial for determining the level of detail that a camera can capture over a given area, affecting the clarity and usability of the video for tasks such as identification and recognition. Higher pixel density results in better image detail. Axis Communications' technical resources on image quality and resolution confirm this definition of pixel density.

A continuously high bitrate in a video stream, even when using H.265 compression, is often due to significant movement within the scene. High levels of motion require more data to be encoded to maintain image quality, resulting in a higher bitrate. This is because the video encoder must frequently update large portions of the image to accurately represent the moving objects. Axis Communications' documentation on video bitrate management indicates that scenes with much movement lead to increased bitrate due to the dynamic changes requiring constant encoding.

Zipstream’s Dynamic GOP (Group of Pictures) conserves bandwidth and storage by skipping new I-frames if the scene is unchanged. I-frames (intra-coded frames) are larger than P-frames (predictive frames) and B-frames (bi-directional frames) because they contain the full image data. By reducing the frequency of I-frames when there is no motion or change in the scene, Zipstream significantly lowers the data rate without compromising image quality. Axis documentation explains how Zipstream’s Dynamic GOP feature optimizes video encoding to conserve resources effectively.

A smoked dome might negatively affect the image quality. Smoked domes can reduce the amount of light reaching the camera sensor, leading to darker and less clear images. While they offer additional privacy and reduce the visibility of the camera’s direction, they can compromise the overall image clarity and brightness. Axis Communications' documentation on dome camera housings and their impact on image quality confirms this.
