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.

OptimizedIR technology in Axis cameras refers to the intelligent adaptation of IR illumination to the camera's field of view. This ensures even illumination across the entire scene, reducing overexposure and underexposure caused by traditional fixed IR lights. The IR LEDs adjust their intensity and spread according to the zoom level and scene requirements, providing optimal image quality in low-light conditions. Axis documentation highlights OptimizedIR as a feature that enhances night-time surveillance by ensuring balanced lighting.

The maximum power level at the powered device for PoE class 2 is 6.49 W. Power over Ethernet (PoE) class 2 devices are designed to consume between 3.84 W and 6.49 W. This classification helps ensure that network devices receive the appropriate power levels required for their operation.

A continuously high bitrate in a video stream, even when using H.265 compression, is often due to significant movement within the scene. High levels of motion require more data to be encoded to maintain image quality, resulting in a higher bitrate. This is because the video encoder must frequently update large portions of the image to accurately represent the moving objects. Axis Communications' documentation on video bitrate management indicates that scenes with much movement lead to increased bitrate due to the dynamic changes requiring constant encoding.
