Axis Communications Updated ANVE Exam Questions and Answers by stefania

The Group of Video (GOV) length setting affects both the bandwidth and storage requirements of video streams. A longer GOV length, which specifies the interval between keyframes in a video stream, reduces the frequency of keyframes, thus lowering the bandwidth consumption. However, it can also increase the storage time on an SD card because fewer keyframes are stored over a given period, making the video stream more compression-efficient.

The H.264 compression standard is highly efficient and can significantly reduce bandwidth and storage requirements compared to Motion JPEG. This is because H.264 uses both intra-frame and inter-frame compression, which reduces the amount of data needed to represent video by eliminating redundant information between successive frames. Axis Network Video documentation states that H.264 can reduce the required bandwidth and storage by up to 50% or more in typical surveillance scenarios, making it an advantageous choice for video compression in surveillance systems.

AXIS Camera Management (ACM) is a powerful tool for managing multiple Axis network devices efficiently. With ACM, administrators can apply templates to devices, which streamlines the configuration process by allowing predefined settings to be distributed across multiple devices. Additionally, ACM facilitates the upgrading of firmware on Axis devices, ensuring that all cameras and encoders are up-to-date with the latest features and security patches. Axis Network Video documentation highlights these capabilities as key features of ACM, enhancing the overall management and maintenance of surveillance systems.
