ANVE Exam Dumps - Axis Communications Certifications Questions and Answers

A camera with a fixed iris is best mounted outside in a shadowed position. Fixed iris lenses do not adjust to changes in light levels, making them less suitable for environments with varying lighting conditions. By placing the camera in a shadowed position, you minimize the impact of direct sunlight and glare, which can cause overexposure and poor image quality. Therefore, the correct answer is C. For more detailed information, refer to Axis Communications' documentation on camera installation and fixed iris lenses.

Managed switches offer a variety of security features essential for maintaining the integrity and confidentiality of network data. IEEE 802.1X port-based authentication ensures that only authorized devices can connect to the network by requiring each device to authenticate itself before gaining access. HTTPS encryption provides secure communication over the network by encrypting the data being transmitted, protecting it from interception and tampering. These two features are critical for securing network traffic and preventing unauthorized access. Axis Network Video documentation highlights the importance of these features in maintaining a secure video surveillance network.

H.264 is a video compression standard that adjusts the bit rate based on the motion in the scene. Increased motion results in a higher bit rate because more data is required to accurately represent the changes between frames. Additionally, a longer Group of Video (GOV) length, which means fewer I-frames and more P-frames in a sequence, reduces the overall bit rate since I-frames are larger and require more data. References can be found in the Axis Communications documentation and technical white papers on H.264 compression.

Axis Coverage Shapes is a tool within Axis' design software that helps determine the optimal placement and specifications of cameras to ensure that identification and surveillance goals are met. It allows the designer to visualize the camera's coverage area and assess the distance at which a person can be identified, ensuring that the camera's placement and specifications align with the security requirements. For more detailed information, refer to Axis Communications' resources on Axis Coverage Shapes.

Multicast is a method of data transmission in which a single stream of data is sent from a source to multiple destinations simultaneously. This technique is especially useful in video surveillance because it allows multiple viewers to receive the same video stream without duplicating the data sent across the network. In other words, the video stream only needs to be sent once from the camera, even though there are multiple viewers, reducing network bandwidth usage. This makes option C correct. For more detailed information, refer to Axis Communications' official documentation on network video fundamentals and multicast usage.

The AXIS M3114-R is designed specifically for use in environments with vibrations, such as transportation. It is rugged and can withstand shocks and vibrations inherent in mobile applications. Other models like the AXIS P3344-VE, AXIS M3014, and AXIS P1344 do not have the same level of vibration resistance. Detailed specifications and use cases for the AXIS M3114-R can be found in the Axis Communications product catalog and datasheets.

To achieve four H.264 streams at 30 fps from the same camera product that can deliver two full resolution 30 fps H.264 streams, the resolution of the streams must be decreased. By lowering the resolution, the camera reduces the amount of data processed and transmitted for each stream, making it possible to support additional streams. Axis Network Video documentation indicates that stream configuration, including resolution and frame rate adjustments, allows cameras to manage multiple streams effectively while maintaining performance.

Using VLANs and IP subnets in a network infrastructure helps segregate surveillance video traffic from other network traffic. This separation improves network security by limiting access to authorized devices only and reducing the risk of video interception by malicious users. It does not inherently provide encryption or establish encrypted communication links, but it enhances security by isolating sensitive video streams. Detailed explanations can be found in Axis Communications network design guides and security best practices documents.

The ONVIF (Open Network Video Interface Forum) standard provides several benefits to end users. One key benefit is that it helps create future-proof systems and more secure investments by ensuring interoperability between different manufacturers' devices, which protects against obsolescence. Additionally, ONVIF increases flexibility and offers greater freedom of choice, allowing users to mix and match devices from different vendors, thereby tailoring their security systems to specific needs without being locked into a single manufacturer's ecosystem.
