ANVE Exam Dumps - Axis Communications Certifications Questions and Answers

Closing the aperture at a fixed focal length increases the f-number (aperture value), resulting in a longer depth of field. This means that a greater portion of the scene will be in focus, both in the foreground and background. A higher f-number indicates a smaller aperture, which allows less light to enter the lens but enhances the sharpness and clarity of the image over a larger depth.

To wire an external 12V relay to the output port of an Axis camera, the GND and I/O1 pins should be used. The GND (ground) provides the necessary electrical return path, and the I/O1 pin is used for the output signal to control the relay. According to Axis technical documentation, these connections allow for proper integration and control of external devices such as relays, ensuring they function correctly with the camera's output capabilities.

The primary reason for using a multisensor panoramic camera versus a single-sensor panoramic camera is to achieve higher pixel density. Multisensor cameras combine images from multiple sensors to create a high-resolution, detailed panoramic view. This approach provides superior image quality and clarity, especially in large areas where high detail is needed. Axis product literature emphasizes the advantage of higher pixel density in multisensor cameras for capturing detailed, wide-area surveillance images.

"Box cameras are known for their straightforward form factor, making it easy to determine exactly where the camera is pointing and where potential blind spots may be."

An explosion-protected camera is specifically designed to contain any internal explosion within its housing. This type of camera is built to operate in hazardous environments where flammable gases or dust may be present. The robust housing prevents the internal explosion from igniting the surrou

nding atmosphere, thereby ensuring safety. Axis Communications offers explosion-protected cameras that adhere to stringent safety standards to prevent ignition and ensure reliable operation in dangerous conditions, as detailed in their product specifications.

"Axis body worn cameras are designed to offload their recordings via docking stations, ensuring secure and efficient transfer of video files."

Using bidirectional predictive interframe in H.264, also known as B-frames, will increase the latency in the system. B-frames depend on both previous and future frames (I-frames and P-frames) for encoding, which requires more processing time and thus increases the latency. This trade-off allows for more efficient compression and smaller file sizes but at the cost of increased delay. References: Axis Communications documentation on H.264 video compression and the use of B-frames.

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.

Axis Official Documentation Extract:

"Axis products support the most widely used video compression formats, including Motion JPEG (MJPEG), H.264, and H.265 (HEVC). These formats allow Axis cameras to provide flexible, high-quality, and efficient video streams suitable for a variety of surveillance needs."

Explanation of Options:

A. H.264: Supported. H.264 is a widely used video compression standard in Axis products.

B. MJPEG: Supported. MJPEG (Motion JPEG) is supported for scenarios requiring individual frames.

F. H.265: Supported. H.265, also known as HEVC, is supported for more efficient compression.

C. DivX: Not supported. DivX is not used in professional surveillance.

D. SIP: Not a video compression format; it’s a communication protocol.

E. RTSP: Not a compression algorithm; it's a streaming protocol.
