Maintenance is essential for ensuring the optimal performance of outdoor cameras running video analytics.
Regular maintenance tasks include cleaning the camera lens, checking and updating firmware, inspecting connections, and verifying that analytics software is functioning correctly. These activities help maintain image quality and ensure the accuracy and reliability of the video analytics. Axis installation and maintenance guides recommend routine maintenance to prevent performance degradation and extend the lifespan of the equipment.

Day & Night cameras from Axis are designed to switch to a low-light mode by removing the IR-cut filter, making them sensitive to infrared light. In this mode, the cameras are most sensitive to IR light at a wavelength of 850 nm, which is commonly used in IR illuminators for night vision. This wavelength provides a good balance between visibility and discreetness, allowing the camera to capture clear images in low-light conditions. Axis Network Video documentation details the sensitivity range and performance characteristics of Day & Night cameras, emphasizing the importance of 850 nm wavelength for optimal night-time performance.

"Motion blur is more prominent when an object moves perpendicularly (across) to the camera because it traverses more pixels per frame, compared to an object moving toward or away from the camera."
- Axis Communications Academy, Network Video Fundamentals, 2022
"Perpendicular movement causes greater pixel change in each frame, resulting in more noticeable motion blur."

Privacy masks in an Axis camera can be activated and deactivated per stream profile. This allows for flexibility in managing different viewing needs and ensuring privacy in specific scenarios. Users can configure privacy masks to appear in one stream but not in another, making it a versatile feature for various applications. Axis Communications' documentation on privacy masks confirms this capability.
