A customer asks for a fixed mini dome with a DC-iris lens. 2.8-10 mm varifocal lens and wide dynamic range. Which of the following cameras is the only choice to fit all of the requirements?
Answer : A
The AXIS P3301 is a fixed mini dome camera that features a DC-iris lens, a 2.8-10 mm varifocal lens, and wide dynamic range (WDR). This combination of features makes it the only suitable choice among the listed options to meet the customer's requirements for a fixed mini dome camera with these specific capabilities. More details can be found in the Axis Communications product specifications and data sheets for the AXIS P3301.
Question 2
Which are the main benefits of OptimizedlR? (Select two)
Answer : C, D
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.
Question 3
How does the AXIS Design Tool allow users to estimate the effects of scene complexity and motion on bandwidth and storage usage?
Answer : D
The AXIS Design Tool helps users estimate bandwidth and storage usage by using a statistical model based on the selected camera model. This tool takes into account factors such as scene complexity and motion to provide accurate estimates, enabling users to plan their surveillance system more effectively.

Question 4
Axis cameras support the ONVIF and VAPIX APIs. Which of the following is true?
Answer : D
VAPIX is Axis' proprietary API (Application Programming Interface) that enables integration and management of Axis network video products. It allows developers to access a wide range of functionalities, such as video streaming, event management, and configuration settings, specifically tailored to leverage the latest capabilities of Axis cameras. ONVIF (Open Network Video Interface Forum) is an industry standard that facilitates interoperability between IP-based security products regardless of manufacturer, supporting basic functionalities for video and audio streaming, PTZ control, and event handling but not exclusively tailored to the latest Axis camera features.
Question 5
If cameras are at risk of being exposed to a corrosive atmosphere, what type of housing should be used?
Answer : B
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.
Question 6
Keeping firmware up to date helps a device to
Answer : B, D
Keeping firmware up to date helps a device stay as cybersecure as possible by addressing vulnerabilities and incorporating security patches. Regular updates ensure that the device is protected against the latest threats. Additionally, updating firmware helps the device remain compatible with the Video Management System (VMS), ensuring that it can work seamlessly with the latest software features and improvements. Reference: Axis Communications security and firmware update policies.
Question 7
What protocol on layer 3 enables network traffic?
Answer : A
On layer 3 of the OSI model, the protocol that enables network traffic is IP (Internet Protocol). IP is responsible for addressing and routing packets of data so that they can travel across networks and reach the correct destination. It provides logical addressing and handles the path through which data is transferred between source and destination nodes. Axis documentation confirms that IP is crucial for network communication and is fundamental for the operation of network video systems.
