ANVE Exam Dumps : Axis Network Video Exam

The IK rating is a measure of a device's resistance to mechanical impact, making it crucial for environments where vandalism is a concern. A higher IK rating indicates better protection against physical attacks, ensuring that the camera can withstand attempts to damage it. Axis cameras designed for high-risk areas typically feature robust housings with high IK ratings, which are specified in their product datasheets and installation guides.

A system designer should recommend the installation of standalone multi-channel video encoders when large numbers of cameras are located near the central monitoring room. This setup allows for efficient centralization of video feeds from multiple analog cameras, converting them to digital signals for easier management and storage. Using multi-channel encoders in this scenario optimizes space and reduces the complexity of wiring compared to installing separate encoders for each camera. Axis Communications' guidelines on transitioning from analog to IP systems support this recommendation.

Fluorescent lighting can cause flickering effects in video due to the way these lights operate. Fluorescent lamps typically flicker at twice the power line frequency (50 Hz or 60 Hz), which can interfere with the camera's frame rate and shutter speed, leading to visible flickering in the recorded video. This effect is more pronounced when the camera's exposure settings are not synchronized with the frequency of the lighting. Axis Network Video documentation discusses the importance of using cameras with anti-flicker settings or adjusting the shutter speed to match the lighting frequency to mitigate this issue.
