ANVE Exam Dumps - Axis Network Video Exam

The aspect ratio of the scene depicted in the image is 16:9. This widescreen format is commonly used in modern video applications, including network video surveillance. The 16:9 aspect ratio provides a wider field of view, which is beneficial for monitoring large areas and capturing more detail horizontally. Axis cameras often support this aspect ratio to provide comprehensive coverage in surveillance environments. The documentation confirms that 16:9 is a standard aspect ratio for many Axis network cameras.

The AXIS Q60 Series cameras are designed to work with 60W PoE to ensure full functionality, including optimal pan and tilt speeds. If connected to a 30W PoE, the camera will still operate, but the pan and tilt functions will be limited in speed due to insufficient power. This limitation is outlined in Axis’s technical documentation for the Q60 Series, which specifies the power requirements and the impact on camera functionality when those requirements are not met.

Axis cameras that have model numbers ending with -E are specifically designed for extreme environments, including those with high temperatures. These cameras are built to withstand harsh conditions and provide reliable performance in challenging environments. The -E designation indicates enhanced durability and temperature tolerance, making them suitable for installations in locations where standard cameras might fail. Axis Network Video documentation highlights the features and specifications of these ruggedized camera models.

To address the blurring that's occurring with faster moving objects in the image, adjusting the exposure settings is the best option. Specifically, reducing the exposure time (shutter speed) will help in capturing clearer images of fast-moving objects by reducing motion blur. This adjustment allows the camera to capture less light per frame, effectively freezing the motion and reducing the blur associated with movement.

Increased noise levels in a scene typically result in higher bandwidth usage. Noise introduces additional variations in the video signal, which the compression algorithm must encode, leading to increased data rates. This is particularly noticeable in low-light conditions where electronic noise can significantly impact the video stream. Axis Network Video documentation explains that noise reduction techniques and proper lighting can help manage and reduce the bandwidth impact caused by increased noise levels in surveillance video.

When dealing with a poorly lit scene, adding light is the most effective option to improve image quality. Proper illumination ensures that the camera's sensor can capture clear and detailed images, reducing noise and enhancing visibility. While adjusting exposure settings, brightness, or changing camera placement can help, they are secondary to the fundamental requirement of adequate lighting.

Gatekeeper is a feature in Axis PTZ cameras that allows the camera to automatically zoom in on an object when motion is detected within a predefined area. This function is useful for focusing on areas of interest, such as entry points or sensitive zones, enhancing security monitoring by providing detailed views of potential security events. Axis Network Video documentation explains that Gatekeeper uses video motion detection to trigger the zoom function, ensuring that important details are captured without manual intervention.

To utilize IEEE 802.1X for connecting a camera to the network, the following are required:

A. An Ethernet switch with support for IEEE 802.1X, which ensures that only authorized devices can connect to the network.

C. A RADIUS server, which is used to manage authentication, authorization, and accounting (AAA) for network access control.

These components are essential for setting up secure network access using IEEE 802.1X.
