Audio detection in Axis cameras is used to detect changes in decibel levels, which can indicate unusual or noteworthy events such as alarms, breaking glass, or raised voices. This functionality does not necessarily require a built-in microphone; it can also work with external microphones. The primary function is to trigger alerts or recordings based on significant changes in the audio environment. Axis Network Video documentation outlines the use of audio detection for enhancing security by monitoring for specific sound patterns or levels.

Image flickering on an AXIS P1344 can often be attributed to the camera's exposure settings. Flickering is usually caused by lighting conditions that fluctuate at a frequency different from the camera's current exposure settings, leading to the perception of flicker. Adjusting the exposure settings can synchronize the camera with the lighting conditions, thus reducing or eliminating the flickering issue. This can be done by accessing the camera’s web interface and navigating to the image settings to adjust the exposure mode or exposure value. According to Axis Communications' product documentation, fine-tuning the exposure settings is a recommended step to mitigate flickering.

The capability to view and record up to four different areas of the whole image of an AXIS P1346 camera is called Multi-view streaming. This feature allows multiple cropped views to be created from a single high-resolution video stream, enabling more efficient use of bandwidth and storage while focusing on specific areas of interest within the full image. For more information, refer to the Axis Communications product documentation and technical notes on Multi-view streaming capabilities.

Video motion detection (VMD) in PTZ (Pan-Tilt-Zoom) cameras is feasible but primarily when the camera is used as a stationary camera. PTZ cameras can activate motion detection when they are not moving, as movement of the camera itself would otherwise trigger the VMD. When the camera is stationary, it can effectively detect motion within its field of view similar to a fixed camera. Therefore, option B is correct. For more detailed information, refer to Axis Communications' guidelines on VMD functionality in PTZ cameras.
