Axis Network Video ANVE Exam Questions

Answer : B

An IR cut filter is used to block infrared light during daylight hours to prevent it from interfering with the camera's sensor. This ensures that the colors captured by the camera appear natural. Without an IR cut filter, the infrared light can cause color distortions, resulting in unnatural-looking images. Axis cameras equipped with IR cut filters switch between day and night modes to optimize image quality in various lighting conditions, as explained in their technical documents and user manuals.

Answer : C

The main benefit of signed firmware is that it allows the device to verify the integrity and authenticity of the firmware before it is installed. This process ensures that the firmware has not been tampered with and is from a trusted source, thereby enhancing the security of the device. Signed firmware prevents unauthorized or malicious firmware from being installed, which is crucial for maintaining the security and reliability of network devices. Axis documentation emphasizes the importance of signed firmware in protecting devices from potential security threats by verifying the firmware's integrity.

Answer : A, C

In an IP-based video system, audio can be transmitted alongside video over the same network, allowing for integrated audio-video surveillance. This enables the simultaneous monitoring of both audio and visual data, enhancing situational awareness. Additionally, some Axis video encoders support audio functionality with analog cameras, allowing these older devices to be integrated into modern IP-based systems and take advantage of audio capabilities. Axis documentation highlights these features, emphasizing the seamless integration of audio and video in IP surveillance solutions and the extended functionality provided by video encoders.

Answer : B

The camera shown in the image is an Axis multidirectional camera, which typically features multiple sensors to cover a wide area. Based on the design and common configurations of Axis multidirectional cameras, it has a total of 4 camera sensors. Each sensor can be independently adjusted to capture different angles and areas, providing comprehensive surveillance coverage. Axis documentation on multidirectional cameras confirms that these models generally come with four sensors for optimal monitoring.

Answer : A

UDP (User Datagram Protocol) has less overhead information compared to TCP (Transmission Control Protocol). UDP is a simpler, connectionless protocol that does not require handshaking or error-checking mechanisms, resulting in lower overhead and faster transmission of data. This makes UDP more efficient for real-time applications such as video streaming, as detailed in Axis Communications' technical guides on network protocols.

Answer : D

Axis thermal cameras are designed to detect activity in both daylight and complete darkness by capturing the heat emitted by objects and people. Unlike traditional cameras that rely on visible light, thermal cameras are effective in various lighting conditions, including complete darkness, fog, smoke, and even camouflaged objects. This makes them suitable for perimeter protection and monitoring in challenging environments. [Reference: Axis Communications - Thermal Cameras]

Answer : C

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.
