When using AXIS People Counter, the camera lens must be facing straight down. This positioning ensures the most accurate counting of people as they pass through the monitored area. The overhead view eliminates obstructions and provides a clear field of vision directly below the camera, which is essential for precise counting. This recommendation is verified by Axis Communications' guidelines on deploying the AXIS People Counter application.
Question # 25
What direction of movement (relative to the camera) do video analytics applications detect more easily?
Video analytics applications detect movement perpendicular to the camera more easily than movement toward or away from the camera. This is because objects moving perpendicular to the camera create more significant changes in the pixel patterns, making it easier for the analytics software to detect and analyze the movement. Movement toward or away from the camera results in smaller changes in pixel patterns, which can be harder to detect accurately. References: Axis Communications documentation on video analytics and movement detection.
Question # 26
Which rating is important when vandalism is a risk?
The IK rating is a measure of a device's resistance to mechanical impact, making it crucial for environments where vandalism is a concern. A higher IK rating indicates better protection against physical attacks, ensuring that the camera can withstand attempts to damage it. Axis cameras designed for high-risk areas typically feature robust housings with high IK ratings, which are specified in their product datasheets and installation guides.

Question # 28
As this person enters the scene, what is true about P-frames?
As a person enters the scene, P-frames (Predictive frames) increase in size. P-frames contain only the changes in the image from the previous frame (I-frame or another P-frame). When there is movement or new objects enter the scene, more data is needed to describe the changes, resulting in larger P-frames. References: Axis Communications documentation on video compression and frame types in H.264.
Question # 29
When designing a network video system, which are the benefits of configuring VLANs? (Select two)
Options:
A.
It increases the network bandwidth
B.
It keeps the network traffic separated from other networks
C.
In some cases, it lowers the bandwidth consumption
Configuring VLANs (Virtual Local Area Networks) in a network video system has several benefits. Firstly, VLANs keep network traffic separated from other networks, enhancing security and ensuring that video data does not mix with other types of traffic. This separation is crucial for maintaining the integrity and security of the video streams. Secondly, VLANs help avoid network congestion by logically segmenting the network, which improves overall network performance and reduces the likelihood of traffic bottlenecks. Axis documentation supports the use of VLANs to enhance network efficiency and security in video surveillance systems.
A full HD sensor has a 1080p resolution. Full HD, or FHD, refers to a resolution of 1920 x 1080 pixels, which is commonly used in high-definition video and surveillance systems for providing clear and detailed images.

Question # 31
Which is true for a multidirectional camera?
Options:
A.
The lenses move automatically when tracking an object
B.
Each sensor is assigned its own IP address
C.
The sensors are movable to enable optimal usage
D.
The image from each sensor is automatically dewarped
A multidirectional camera is equipped with multiple sensors that can be independently adjusted to cover different areas. This flexibility allows for optimal usage of the camera by positioning each sensor to capture specific scenes or angles. These sensors are typically fixed in place once set up, but their initial placement can be adjusted to ensure comprehensive coverage. Axis documents specify that multidirectional cameras are designed for customizable installation to meet varying surveillance needs.
Question # 32
which describes an opportunistic attack?
Options:
A.
Typically performed by a person with legitimate access
B.
The attacker is usually not acquainted with the target
C.
Often organized, with several people involved
D.
Targeted at a specific system with a specific goal
An opportunistic attack is characterized by the attacker not being acquainted with the target. These attacks are typically random and take advantage of any available vulnerability rather than being specifically targeted at a particular system or organization. The attacker usually seeks easy targets with known vulnerabilities and acts quickly when an opportunity arises. Axis security documentation describes opportunistic attacks as generally unsophisticated, focusing on exploiting common and readily available weaknesses in systems.
Question # 33
What do routers use to determine where to send data packets?
Routers use IP addresses to determine where to send data packets. IP addresses provide the unique identification needed for routing data across networks, enabling the router to direct packets to their correct destinations. This fundamental aspect of network communication is outlined in Axis Communications' documentation on network protocols and IP-based systems.
