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.
What device is used to forward data from one LAN to another?
A router is a device used to forward data from one Local Area Network (LAN) to another. It operates at the network layer (Layer 3) of the OSI model and uses IP addresses to determine the best path for data packets to travel between networks. Routers connect multiple networks, manage traffic, and facilitate communication between different network segments.

When recording a night scene with IR, what is the consequence of using a day-and-night camera without an IR-corrected lens?
When recording a night scene with IR, using a day-and-night camera without an IR-corrected lens can cause the focus to shift. This happens because IR light and visible light have different wavelengths and refract differently through the lens. An IR-corrected lens is designed to handle both types of light without causing a focus shift, ensuring sharp images in both day and night conditions. Reference: Axis Communications product guides on day-and-night cameras and IR-corrected lenses.
Which of the following statements about multicast video streaming are true? (Choose three)
Multicast video streaming has several important characteristics:
A. Multicast can help to save bandwidth in a network because it allows the same video stream to be delivered to multiple users simultaneously, reducing the need for multiple unicast streams.
B. Multicast can typically not be used to provide video over the internet because many routers and firewalls do not support multicast traffic across the internet, which is more suited for local network environments.
D. Multicast extends the viewer capacity of a camera or an encoder from 10-20 to an unlimited number, as it does not rely on multiple individual connections to distribute the video stream.
A camera is positioned where backlighting is a problem. What would be the preferred action?
Axis P-iris technology is designed to optimize the iris position for optimal depth of field, resolution, and image contrast. It also helps in managing challenging lighting conditions such as backlighting by controlling the amount of light reaching the image sensor. This allows the camera to produce clear images even when facing direct sunlight or other bright light sources.
