ANVE Exam Dumps - Axis Communications Certifications Questions and Answers

If a PoE (Power over Ethernet) switch is unable to supply sufficient power to a network device, a midspan, also known as a PoE injector, should be used. A midspan is an external device that adds power to the Ethernet cable, thus providing the necessary power to the network device. This is particularly useful when existing network infrastructure cannot be upgraded to meet power requirements. According to Axis documentation, midspans are recommended to ensure adequate power delivery for network devices that require PoE.

Outdoor-ready cameras from Axis can be equipped with a cooling fan and a heater element to handle varying weather conditions. The cooling fan helps manage high temperatures by preventing overheating, while the heater element ensures the camera operates effectively in cold environments by preventing frost and condensation. These features allow the camera to maintain optimal performance and reliability regardless of the weather, as specified in Axis' product datasheets and technical specifications for outdoor models.

Typically, a system designer calculates the pixel density based on the horizontal resolution and the field of view. Pixel density is crucial in determining the level of detail a camera can capture in a specific area. Horizontal resolution refers to the number of pixels along the horizontal axis of the image sensor, while the field of view is the extent of the observable area captured by the camera. This calculation helps in ensuring that the camera setup meets the surveillance requirements.References: Axis Communications Design Tool

The camera sensors in Axis’ multidirectional cameras can be individually adjusted. This flexibility allows each sensor to be positioned independently, enabling optimal coverage of the desired areas. Such adjustability ensures that a single camera unit can cover multiple directions or areas, enhancing the efficiency and effectiveness of the surveillance setup. Axis' multidirectional camera specifications and manuals provide detailed information on this feature.

ACAP (Axis Camera Application Platform) analytics run directly on the device. This means that the processing and analysis of data occur on the camera itself, rather than on a separate server or in the cloud. Running analytics on the device reduces the need for additional hardware and network bandwidth, and it allows for faster decision-making and real-time alerts. This information is confirmed by Axis Communications' documentation on ACAP.

A P-iris lens has better iris control in all lighting conditions. P-iris (Precise iris) lenses are designed to optimize the depth of field, contrast, and resolution of the camera by precisely controlling the iris opening, ensuring optimal image quality in varying light conditions. This technology is superior to manual, fixed, and DC-iris lenses. Axis Communications' product specifications highlight the benefits of P-iris lenses in maintaining image quality across different lighting scenarios.

Axis cameras offer several advanced focus technologies to enhance image clarity and ease of use. Focus Pinpoint allows for precise manual focus adjustments, ensuring sharpness in critical areas. Focus Recall enables cameras to remember and quickly return to pre-set focus positions, which is useful for surveillance scenarios where the camera frequently moves between different points of interest. According to Axis documentation, these technologies are designed to improve the accuracy and efficiency of camera setup and operation.

A MAC (Media Access Control) address is a unique physical address assigned to network interfaces for communication on the physical network segment. It is used for direct data exchange within a network, ensuring that data packets are delivered to the correct device. Unlike IP addresses, MAC addresses operate at the data link layer (Layer 2) of the OSI model and are hard-coded into the network interface card (NIC) by the manufacturer.

Lowering the shutter speed can produce motion blur because the camera sensor is exposed to light for a longer period, capturing the movement of objects within the frame. This results in a blurry representation of moving objects, which can be useful for artistic effects but undesirable for capturing fast-moving subjects clearly.

Axis Sharpdome technology provides the advantage of enabling PTZ cameras to see above the horizon. This innovative design allows for 360-degree coverage and significantly enhances the field of view, making it possible to monitor areas both above and below the camera’s position without distortion. This feature is particularly beneficial for applications requiring extensive coverage and flexible monitoring angles. Axis Communications' product details on Sharpdome technology highlight this capability.
