Axis Communications Updated ANVE Exam Questions and Answers by mahnoor

The setting that would best adjust a hard yellow tint in the images is the white balance. Adjusting the white balance corrects color casts by accounting for the color temperature of the light source, thereby producing more natural colors in the image. In the example images, modifying the white balance would neutralize the yellow tint and restore accurate colors. Axis cameras have white balance settings that can be adjusted manually or set to automatic for optimal color representation. Further details can be found in Axis Communications' camera setup and image optimization documentation.

H.264 compression technology is designed to be more efficient than Motion JPEG, especially at higher frame rates. This is because H.264 uses inter-frame compression, which reduces redundancy by encoding differences between successive frames, leading to significant bandwidth savings. Motion JPEG, on the other hand, compresses each frame independently, resulting in higher bandwidth usage. [Reference: Axis Communications - Video Compression Technologies]

To reduce the impact on recorded video during server maintenance, Video Management Software (VMS) partners can incorporate local storage at the camera. This feature allows the camera to continue recording video on its internal storage (such as an SD card) during network or server downtime, ensuring continuous video capture. Once the server is back online, the recorded footage can be transferred back to the central storage. Axis cameras support local storage options, which are detailed in Axis Communications' product documentation and VMS integration guides.

According to Johnson's criteria, the detection range for a person with an AXIS Q1921 with a 60 mm lens in clear weather is 1200 meters (3900 feet). This means that a human observer is able to detect a person at this distance with a 50% probability. Johnson's criteria is a widely accepted method for calculating the probability of detection, recognition, and identification of objects in surveillance imagery.
