Free Practice Questions for Axis Communications ANVE Exam

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.

The AXIS M3204 is a cost-effective mini dome camera with a varifocal lens. It does not include DC-iris or audio capabilities, making it suitable for the specified requirements. The other options either include additional features that are not needed or do not meet the cost-effectiveness criteria. For detailed product specifications, refer to Axis Communications' datasheets and product catalogs.

Infrared (IR) illuminators with a wavelength of 940 nm do not produce any visible glow. This wavelength is completely invisible to the human eye, making it ideal for covert surveillance applications where the presence of IR illumination needs to be undetectable. Other wavelengths like 650 nm, 750 nm, and 850 nm can produce a faint red glow that may be visible in low light conditions.

Focusing a camera improves image clarity and detail but also increases the bandwidth. This happens because a sharper image contains more detailed information, requiring more data to transmit over the network. Hence, the bandwidth usage increases as the camera focuses more accurately.

A DNS (Domain Name System) server translates human-readable domain names (like www.axis.com ) into IP addresses that computers use to identify each other on the network. This process is essential for accessing websites and other resources on the Internet using user-friendly domain names instead of numerical IP addresses.

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.

Continuous guard tours involve constant movement of the camera, which limits the effectiveness of H.264 compression. H.264 achieves high compression ratios by identifying and removing redundancies between frames, but continuous motion reduces these redundancies, leading to higher bit rates and, consequently, increased storage consumption. For more details, refer to Axis Communications' technical documentation on H.264 compression and PTZ camera operations.

DHCP (Dynamic Host Configuration Protocol) is a network management protocol used on IP networks. It automates the process of configuring devices on IP networks by assigning IP addresses to devices, allowing them to communicate on the network. The DHCP server dynamically assigns IP addresses from a predefined pool and leases them to devices for a specified period. This eliminates the need for manual IP configuration and helps avoid IP address conflicts. References to Axis documentation confirm that DHCP is essential for managing and automating IP address allocation in networked environments.

To achieve identification at 80 pixels per face for a scene that is 2 meters (6 feet 7 inches) wide, a minimum resolution of 1280 x 720 is needed. This calculation ensures that each face captured in the frame meets the pixel density requirement for clear identification purposes.

When changes made to image clarity within the camera web interface are not reflected within a Video Management Software (VMS), it is often due to the VMS having its settings and configurations that can overwrite those made directly on the camera. Many VMS solutions are designed to manage and standardize settings across multiple cameras, ensuring consistency in video quality and performance. This functionality can override local changes made on the camera interface. According to Axis Network Video documentation, this behavior is typical in integrated systems where VMS settings take precedence to maintain uniformity across all connected devices.
