After an installer sets up a motion detection window they then zoom out the camer
a. How will this affect the camera's ability to detect motion if no settings are changed?
When a camera is zoomed out, the field of view increases, causing each object or movement to cover fewer pixels. As a result, more pixels need to change to trigger motion detection. This means the motion detection sensitivity may be reduced unless adjustments are made to the detection settings. For more information, refer to Axis Communications' motion detection setup guides.
When using an external IR illuminator, what can happen if the beam angle is significantly narrower than the field of view?
When using an external IR illuminator with a beam angle significantly narrower than the field of view, the exposure may be uneven. This can result in parts of the image being overexposed (too bright) while other parts remain underexposed (too dark). Ensuring that the beam angle of the IR illuminator matches the field of view of the camera is essential for achieving uniform illumination across the entire surveillance area.

If cameras are at risk of being exposed to a corrosive atmosphere, what type of housing should be used?
If cameras are at risk of being exposed to a corrosive atmosphere, stainless steel housing should be used. Stainless steel provides excellent resistance to corrosion and is suitable for harsh environments where the camera might be exposed to chemicals, saltwater, or other corrosive substances. This ensures the longevity and reliability of the camera in such conditions. Axis Communications' documentation on camera housings and environmental considerations supports this recommendation.
Which are the main benefits of OptimizedlR? (Select two)
OptimizedIR technology in Axis cameras adjusts the IR illumination to match the camera's field of view. This ensures that the IR light is evenly distributed across the scene, reducing the risk of overexposure and enhancing image quality. Furthermore, this alignment helps to maintain image clarity and detail by preventing hot spots and ensuring a balanced exposure across the entire frame. According to Axis documentation, these benefits help improve the effectiveness of night-time surveillance and reduce the need for additional external IR illuminators.
What is the appropriate usage for an Axis thermal camera?
Axis thermal cameras are designed to detect activity in both daylight and complete darkness by capturing the heat emitted by objects and people. Unlike traditional cameras that rely on visible light, thermal cameras are effective in various lighting conditions, including complete darkness, fog, smoke, and even camouflaged objects. This makes them suitable for perimeter protection and monitoring in challenging environments. [Reference: Axis Communications - Thermal Cameras]
