Axis Communications Updated ANVE Exam Questions and Answers by kornelia

Electronic image stabilization (EIS) helps reduce the bandwidth for a camera by stabilizing the video feed, especially in scenarios where the camera is mounted on a pole or other structure susceptible to vibrations. EIS compensates for camera shake and movement, resulting in smoother video and less variation in the scene, which in turn reduces the amount of data required for compression and transmission.

AXIS M3057-PLVE MkII and AXIS P1378-LE both have built-in IR LED illumination. This feature is crucial for enhancing visibility in low-light conditions or complete darkness, making them suitable for various surveillance applications. The built-in IR LEDs ensure that these cameras can provide clear images even in challenging lighting environments.

Germanium is used for thermal camera lenses because it is transparent to infrared wavelengths. This transparency allows infrared radiation to pass through the lens and reach the camera sensor, enabling the capture of thermal images. Germanium's optical properties make it an ideal material for thermal imaging applications. References: Axis Communications thermal camera specifications and technical documentation.

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.
