Axis Communications Updated ANVE Exam Questions and Answers by curtis

12 V and 24 V DC power sources are becoming increasingly popular compared to 24 V AC because it is easier to back-up DC with batteries. DC power systems can be directly connected to battery backup systems without the need for conversion, making the implementation simpler and more reliable during power outages. This efficiency in backup capability is one of the primary reasons for the shift from AC to DC in many applications, including surveillance systems.

When using the view area functionality in Axis cameras, each view area can have its own independent video stream. Additionally, each view area can have its own exposure control setting and text overlay setting. This allows for customized video streams with different exposure settings tailored to specific areas within the camera's field of view, as well as unique text overlays for each view area, providing flexibility in video management and presentation.

Focusing a camera with an auto iris is more accurate when set during lowlight conditions. In low light, the iris opens wider, resulting in a shorter depth of field. This forces the focus to be more precise within that narrower range, ensuring that the focus is set correctly. When lighting conditions improve and the iris closes down, the depth of field increases, maintaining a broader range of focus.

The capability to view and record up to four different areas of the whole image of an AXIS P1346 camera is called Multi-view streaming. This feature allows multiple cropped views to be created from a single high-resolution video stream, enabling more efficient use of bandwidth and storage while focusing on specific areas of interest within the full image. For more information, refer to the Axis Communications product documentation and technical notes on Multi-view streaming capabilities.
