The primary purpose of a router is to forward traffic between different networks, such as between a local network and the internet. This is essential for directing data packets to their correct destinations across diverse networks. Therefore, the correct answer is B. For more detailed information, refer to Axis Communications' documentation on networking fundamentals and router functions.

Infrared (IR) illuminators with a wavelength of 940 nm do not produce any visible glow. This wavelength is completely invisible to the human eye, making it ideal for covert surveillance applications where the presence of IR illumination needs to be undetectable. Other wavelengths like 650 nm, 750 nm, and 850 nm can produce a faint red glow that may be visible in low light conditions.

When installing Axis cameras outdoors, it's crucial to protect the equipment from electrical surges, which can occur due to lightning or other power disturbances. Installing a surge suppressor in front of each camera helps prevent damage from these surges, ensuring the longevity and reliability of the camera system. While grounding endpoints and using UPS for the network switch are also good practices, surge protection directly in front of each camera is specifically emphasized in Axis’s best practices for outdoor installations.

The first time an Axis camera's Live View is accessed, the user is prompted to configure a root password. This step is essential for securing the camera and preventing unauthorized access. Setting a strong root password ensures that only authorized users can modify the camera's settings and view the video stream.
