High-density target capture is a specialized capability designed for scenarios with high pedestrian traffic, such as urban squares or station exits, where crowd density can exceed 100 person-times in a single frame. This feature ensures accurate trajectory generation and optimal snapshots without missed or false captures in challenging environments. The technical architecture of this feature is built upon three fundamental pillars, as the system requires that high-density target capture enabled by: object detection algorithm and target trajectory generation algorithm + chip computing power + large-capacity memory .

Hardware requirements are particularly stringent, necessitating a professional AI chip, such as a 4 TOPS NPU, to manage the processing load of tracking up to 200 targets per frame. Large- capacity memory, typically 4 GB of DDR, is also vital to ensure an ultra-low snapshot repetition rate of less than 8%. While high-frequency exposure—specifically T-Shot double-exposure technology—is an advanced imaging technique used to capture clear snapshots of vehicles and targets simultaneously at night, it is a distinct imaging enhancement rather than a prerequisite for the high-density capture logic itself. High-frequency exposure focuses on resolving illumination and motion blur, whereas high-density capture focuses on the computational capacity to detect and track a massive volume of objects.

The correct answer is B. FALSE . The statement is internally inconsistent because it says there are nine parts , but then lists more than nine items . More importantly, the construction sequence in the training material is described differently. The document states that civil engineering implementation includes “onsite measurement and routing, site arrangement, foundation pit excavation, lightning protection and grounding, foundation pit bedding, reinforced cage making, foundation template making, concrete casting, concrete maintenance, foundation pit backfilling, handhole making (optional), and trenching and cabling (optional)”

That official sequence does not match the wording in the question exactly. Terms such as construction material entry , ground part connecting , template removal , and muck backfilling are either not stated in the same form or are not presented as part of a fixed nine-step list. From a professional project-delivery viewpoint, foundation construction is indeed a staged civil process, but the exam statement is inaccurate because both the count and the listed procedure names do not align with the material. Therefore, the statement should be judged false.

The incorrect statement is D . The domain interconnection capability is described in a one-way supervisory model in which the upper-level domain can consume resources and services provided by the lower-level domain . The material explicitly states that “Users in the upper-level domain can view the alarms reported by the lower-level domain” , “Users in the upper-level domain can set recording plans for cameras in the lower-level domain” , and “Users in the upper-level domain can view live video and recordings … from all cameras in the lower-level domain. In addition, the users can perform PTZ controls over all cameras in the lower-level domain” . These statements directly validate A, B, and C .

The backup direction also confirms why D is wrong. The material states that “Users in the upper-level domain can use the live video and recording backup function to back up recordings of a lower-level domain to MPUs of the local domain, domains of the same level, and upper-level domain” . That means the supported backup flow is from the lower-level domain upward or laterally, not from the upper-level domain down to a lower-level domain. Therefore, D is the incorrect statement.

The correct answer is A. TRUE . The idea of an observation circle in video site planning is to form a perimeter-style observation system around a protected area so that targets can be detected, tracked, and controlled at key boundary points. This matches the planning logic used in intelligent vision deployments, where site selection focuses on strategically important locations. The material identifies priority planning positions such as “Road intersections and entrances and exits” and “Key areas in cities” . These are exactly the kinds of points used to form an observation circle.

From a professional planning perspective, the observation circle concept is not just about placing cameras randomly; it is about creating an enclosed prevention-and-control framework by covering the external boundary and critical transition points of an area. Inter-city boundaries and city entrances or exits are typical examples because they are natural choke points for observation, vehicle monitoring, and event response. By surrounding the target area through layered site deployment, the system improves awareness, traceability, and early warning capability. Therefore, the statement correctly describes the purpose and example of an observation circle.

The Software Development Kit (SDK) protocol serves as a powerful interface for third-party applications to manage and interact with Huawei's intelligent vision devices. It offers a comprehensive range of functionalities that cover the entire lifecycle of device operation and security management. Basic features supported include live video viewing, where the SDK client sends a live video viewing request to the camera, as well as voice intercom and broadcast capabilities for two-way communication. It also provides granular control over device hardware, such as Pan-Tilt-Zoom (PTZ) operations and the modification of various parameter settings.

Beyond basic management, the SDK is deeply integrated with the system's intelligent capabilities. It supports security deployment and withdrawal, allowing users to activate or deactivate alarm monitoring remotely. Specifically, before invoking the alert deployment and withdrawal function, you need to invoke the alarm reporting callback function. Once deployed, the system can report a wide variety of intelligent analysis results, including motion detection, tripwire crossing detection, and loitering detection. This makes the SDK a versatile and essential tool for developers building integrated security solutions that require both standard device management and advanced intelligent vision analytics.

The correct answer is B. FALSE . The installation guidance in the material does confirm that radar is used in “highway scenarios and accurate speed estimation scenarios” and includes alignment steps such as “Adjust the bubble level. When the bubble is in the center, the radar is horizontal” . However, the statement is too absolute because it says the radar is placed right above the lane , which is not a general rule for radar deployment.

In real highway and checkpoint engineering, radar installation depends on the capture model, lane layout, pole position, and the coordination between radar and camera fields of view. The key requirement is that the detection area be aligned correctly with the intended capture zone, not that the radar must always be mounted directly above the lane center. Many practical deployments use side-mounted or offset positions on poles or beams so the radar can still cover the target lane accurately while matching the camera’s observation geometry. Since the essential requirement is proper alignment with the capture area rather than mandatory overhead placement, the statement as written is inaccurate.

The correct answer is A because the IVS3800 requires dedicated AI accelerator hardware to perform intelligent target analysis and vehicle analysis workloads. These functions rely on inference acceleration, not simply on general-purpose storage hardware. The training content directly links IVS3800 intelligent analysis capability to accelerator-card deployment by stating “Insert a maximum of six Ascend accelerator cards in slots 1 to 6” and then listing service capacities such as “Vehicle analysis … 360 channels in video mode” and “Object classification … 360 channels” for the accelerator-enabled configuration . This clearly shows that intelligent analysis capability is enabled by the AI accelerator card.

The other options do not satisfy this requirement. NVMe cards and SAS disks are storage components used for data access, caching, or storage expansion, but they do not provide the AI computing capability needed for intelligent analysis. T4 GPU is not the hardware specified in the material for IVS3800 intelligent target or vehicle analysis. Huawei identifies the Ascend AI accelerator card as the required component. Therefore, A is the correct answer.

The correct answer is A because the SDC OS is designed with open northbound interconnection capability for platform integration. The material explains that “Standard interfaces such as ONVIF are used to connect cameras to the IVS platform” and further states that the open SDC OS supports camera connection through northbound access protocols such as “ONVIF, GB/T 28181, and GA/T 1400”

This directly confirms option A .

In practical intelligent vision deployment, these protocols are essential for interoperability between cameras, platforms, and third-party systems. ONVIF is widely used for standardized video surveillance interoperability. GB/T 28181 is important in many public-security and video networking scenarios. GA/T 1400 is commonly associated with structured data and public-security video information exchange. The other options list either general IT service protocols or physical interfaces, which are not the defined northbound camera access protocols in this context. Therefore, A is the correct answer because it precisely matches the supported protocol set described in the HCIP Intelligent Vision material.

The correct answer is A because WDR is the standard method for handling scenes with strong contrast between bright background light and a darker foreground target. In a backlit scenario, the camera must balance very bright and very dark regions at the same time. If this is not handled correctly, the foreground subject appears too dark. WDR addresses exactly this problem by improving detail retention in both bright and dark parts of the scene.

This is consistent with the exposure principle emphasized in the material, which states that “T-Shot, Huawei’s patented exposure technology, enables optimal imaging of targets and vehicles at the same time” and explains that “Traditional exposure technology cannot correctly expose targets, motor vehicles, and non-motorized vehicles in one image” . That same engineering logic is what makes WDR the right correction for backlit darkness. By contrast, HLC is mainly used to suppress overly bright highlights such as headlights, not to brighten a dark foreground in a backlit scene. FoV and focal length affect framing and magnification, not dynamic-range correction. Therefore, A is the correct answer.

The Open Network Video Interface Forum (ONVIF) provides a standardized framework for the interoperability of IP-based physical security products. These standards are organized into specific "Profiles" that define the features supported by devices and clients. Standard interfaces such as ONVIF are used to connect cameras to the IVS platform, facilitating a future-proof ecosystem where hardware from different vendors can communicate seamlessly.

Among the recognized standards, Profile S is the most common, used for basic video streaming and configuration. Profile T is a more modern standard designed for advanced video streaming, specifically supporting H.265 encoding and metadata reporting. Profile A is utilized for broader access control configurations, allowing for the integration of security management systems. Other profiles include Profile G for edge storage and Profile Q for quick installation. However, Profile B is not a recognized ONVIF standard profile. Adhering to these standardized formats ensures that recording streams can be accessed through external interfaces and that the system provides a channel for reporting metadata (structured data) for exchange with the platform, regardless of the underlying hardware differences.

The correct answers are A, B, and C . The login-address logic is consistent with Huawei platform addressing rules. The material states that when a service is deployed in clustered form, the floating IP must be used, for example: “If the BMU is deployed in two-node cluster mode, enter the external service floating IP address of the BMU” . That directly supports the cluster half of A , and the corresponding single-node logic uses the normal external service address rather than a floating address.

The iClient also works across multiple Huawei platform products, which is why product selection during login is required in practice. In addition, the inter-platform relationship must be established before intelligent analysis services can be configured in platform mode. The material explicitly states “Before connecting two domains with each other, configure the local domain code and external domain information on platforms in both domains” . This directly supports C and also proves why D is false: the connection is not configured only on the iClient; it must be configured on the involved platforms themselves. Therefore, A, B, and C are the correct statements.

During the commissioning and operation of video surveillance clients, such as the iClient, maintaining optimal playback performance is vital for accurate observation. A common technical recommendation is to avoid superimposing the video pane playing live video with the window or dialog box of another program . This is because the video decoding and rendering process on a PC involves high-frequency data transfer between the CPU/GPU and the screen buffer. When another application's window is placed over the active video pane, the computer's graphics subsystem must constantly recalculate which pixels to display, often leading to artifacts or video stuttering .

This phenomenon is especially prevalent when viewing high-resolution streams (such as 4K or 1080p) or when the client is handling multiple concurrent video windows. Overlapping windows can disrupt the hardware acceleration pathways, forcing the system to rely on software rendering, which significantly increases latency. To ensure a smooth "UHD video viewing" experience and to maintain the integrity of the visual data—which is necessary for identifying targets or verifying alarms—users should keep the video interface clear of obstructions. This best practice ensures that the frames are rendered sequentially and clearly, preventing the loss of critical detail during real-time monitoring.

The Cloud Service Platform (CSP) is the underlying infrastructure that manages containers, resources, and services for the intelligent vision platform. Routine maintenance and health checks are essential to ensure the continuous availability of video surveillance services. A comprehensive routine check of the CSP encompasses multiple layers of the system architecture.

First, the License status must be verified to ensure that all intelligent functions and channel capacities remain authorized and active. Second, monitoring CPU and memory usage is critical to identify potential resource bottlenecks that could lead to service instability or video stuttering. Third, for systems deployed in high-availability environments, the Cluster running status (including two-node cluster heartbeat and synchronization) must be checked to ensure failover capabilities are intact. Finally, since the platform utilizes a microservice architecture, checking the CSP and container running status is mandatory to verify that all functional modules (like the VCNAPI or BMU) are active and isolated as intended. By performing these checks regularly, administrators can proactively address issues before they trigger critical system alarms or data loss.
