Axis Network Video Exam Practice Test

Answer : B

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. Reference: Axis Communications Design Tool

Answer : C

The built-in IR LEDs ensure that these cameras can provide clear images even in challenging lighting environments. Reference: AXIS M3057-PLVE MkII, AXIS P1378-LE

Answer : B

Firmware upgrades are efficiently installed using AXIS Device Manager. This tool allows for centralized management of Axis devices, enabling easy firmware updates, configuration changes, and maintenance tasks across multiple devices simultaneously. Axis Device Manager streamlines the process, ensuring that devices remain up-to-date with the latest features and security improvements. Detailed instructions for using AXIS Device Manager are available in Axis' support documentation and user manuals.

Answer : C

The device shown in the image is an SFP (Small Form-factor Pluggable) module. SFP modules are used to connect network devices over fiber optic or Ethernet cables, enabling high-speed data transmission. These modules are commonly used in network cameras and other IP-based devices to ensure reliable and efficient network connectivity. Axis provides various SFP modules that are compatible with their network devices, as outlined in their product datasheets and connectivity guides.

Answer : B

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.

Answer : C

A decoder allows for displaying digital live video on a monitor. Axis decoders convert digital video streams from network cameras into standard video signals that can be displayed on monitors. This is particularly useful in surveillance setups where live monitoring on standard displays is required. Axis offers various decoders designed for seamless integration with their camera systems, as detailed in their product documentation and solution guides.

Answer : B

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.
