Axis ANVE Exam Dumps

The main benefit of using Power over Ethernet (PoE) is cost reduction in installation. PoE allows network cables to carry both data and power, eliminating the need for separate power lines and reducing the amount of cabling required. This simplifies installation, reduces material costs, and allows greater flexibility in camera placement. Axis Communications notes that PoE significantly cuts down on installation expenses by streamlining the infrastructure needed for network devices.

The product name extension '-L' is recommended for environments requiring low-light performance. Axis cameras with the '-L' extension are equipped with integrated IR illumination, making them suitable for low-light or nighttime surveillance. This ensures clear and detailed images even in challenging lighting conditions. Axis Communications' product naming conventions and specifications confirm this recommendation.

The maximum distance for a 100BaseTX Ethernet carrying 802.3at PoE connection between a switch and a camera without any extenders or repeaters is 100 meters (328 feet). This standard distance is applicable for most Ethernet networks and ensures reliable power and data transmission over the specified length.

Low contrast between an object and its background makes video analytics more challenging. Video analytics algorithms rely on distinguishing features and differences between objects and their surroundings to detect and analyze activity. When contrast is low, it becomes harder for these algorithms to accurately identify and track objects, leading to potential errors and reduced performance. Axis documentation highlights the importance of adequate contrast for effective video analytics and suggests measures to enhance contrast where necessary.

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.
