The corridor format is particularly useful for scenes such as the one depicted because it optimizes the camera's field of view for narrow, vertical areas. Traditional horizontal formats waste much of the frame on walls or empty spaces when monitoring hallways, staircases, or aisles. By rotating the camera 90 degrees and using the corridor format, you maximize the vertical field of view, allowing for better coverage and more effective surveillance in such environments. Axis Communications documents and product guides frequently highlight this advantage for corridor format applications.
Question 26
Session Initiation Protocol (SIP) is used to set up
peer-to-peer calls, peer-to-remote calls, SIP dial a station.
C.
SIP service calls, SIP trunk calls, peer-to-peer calls.
D.
SIP trunk calls, SIP service calls, SIP remote calls.
Answer:
A
Explanation:
Session Initiation Protocol (SIP) is used to set up peer-to-remote calls, peer-to-peer calls, and SIP trunk calls. SIP is a signaling protocol widely used for initiating, maintaining, and terminating real-time communication sessions, including voice, video, and messaging applications. It facilitates communication between endpoints, whether they are directly connected or through a SIP trunk. Axis Communications' technical documentation on SIP and VoIP solutions confirms these uses.
Question 27
The main benefit of signed firmware is that
Options:
A.
only super administrators are able to initiate a firmware upgrade.
B.
only one device at a time is upgraded, to avoid interruptions.
C.
the integrity of the firmware can be verified by the device before upgrading.
D.
the upgrade can be scheduled to take place at a non-critical time.
Answer:
C
Explanation:
The main benefit of signed firmware is that it allows the device to verify the integrity and authenticity of the firmware before it is installed. This process ensures that the firmware has not been tampered with and is from a trusted source, thereby enhancing the security of the device. Signed firmware prevents unauthorized or malicious firmware from being installed, which is crucial for maintaining the security and reliability of network devices. Axis documentation emphasizes the importance of signed firmware in protecting devices from potential security threats by verifying the firmware's integrity.
Question 28
AXIS Site Designer has which feature?
Options:
A.
Firmware recommendations
B.
Bandwidth and storage estimation
C.
BIM data summary
D.
Site maintenance planner
Answer:
B
Explanation:
AXIS Site Designer is a tool that helps in designing and planning surveillance systems. One of its key features is bandwidth and storage estimation, which allows users to calculate the required network bandwidth and storage capacity based on the selected cameras and their settings. This feature ensures that the surveillance system is properly scaled and resources are efficiently allocated. References: Axis Communications AXIS Site Designer tool documentation and user guides.
