H12-521_V1.0 HCIP-Intelligent Vision V1.0 Questions and Answers

The correct answer is C . In manual zoom lens terminology, N--F stands for Near to Far , which is the focus adjustment range, while W--T stands for Wide to Tele , which is the focal length or zoom adjustment range. This is standard optical-camera labeling and is consistent with the training material’s broader treatment of camera angle and image adjustment, where physical image tuning is performed through controlled mechanical or optical adjustment rather than through resolution changes alone. The material also shows that image framing and observation behavior depend on controlled camera adjustment, for example through tilt, horizontal, and vertical tuning during installation.

From an optical engineering standpoint, focus adjustment changes the sharpness plane of the subject, while focal length adjustment changes the field of view and magnification. Therefore, a technician first uses the W--T ring to set the desired scene scale and then uses the N--F ring to make the image sharp at the chosen distance. Since the question asks which function each labeled knob performs, N--F = adjust the focus position and W--T = adjust the focal length , making C the only correct option.

The correct answer is A. TRUE . In IVS3800 and Lite Edge network construction, the service plane relies on TOR switching for high-bandwidth service traffic, and link bundling is a standard design approach to provide bandwidth aggregation and redundancy. The material identifies the service-plane access layer explicitly: “Service TOR: TOR access switch on the service plane. The 10 GE optical port or GE port on the service plane is connected to the switch. CE6800 series switches are recommended” . This directly confirms that service TOR switches are a required part of the service-plane topology.

In practical Huawei data-center-style deployment, when multiple service links are aggregated between servers and TOR switches, eth-trunk must be configured, and static LACP support is used to ensure the bundled links operate correctly and consistently. That requirement aligns with standard network design logic for service-plane access in container-based edge environments, where stability and predictable uplink behavior are essential. Because Lite Edge depends on reliable service-plane connectivity and TOR-based aggregation, the statement that service TOR switches need to support static LACP mode and require eth-trunk configuration is correct.

Video structuring is the essential process of converting unstructured video content into searchable, organized data. This capability is integrated across the Huawei Intelligent Vision architecture, existing at both the front-end (cameras) and the back-end (platforms). Huawei's Software-Defined Cameras (SDC) are equipped with professional AI chips, such as the Ascend 310 or Hi3559A, which provide the high-performance processing required to perform this task locally. These AI chips can even replace backend servers to structure full video features, maximizing network-wide intelligent analysis efficiency. By performing structuring at the edge, the system reduces the bandwidth required to transmit full video streams to the central cloud while maintaining real-time awareness.

Simultaneously, Huawei’s intelligent video cloud and big data platforms provide robust back-end structuring capabilities for historical or live video analysis. These platforms utilize advanced algorithms to automatically generate structured data from massive video feeds. As noted in the documentation, video search intelligently analyzes unstructured original video data and automatically generates structured data based on the proper algorithms. This dual-layer approach allows for flexible deployment depending on whether real-time edge processing or high-volume centralized analysis is required for a specific security scenario.

The correct answer is A. TRUE . In IVS deployment practice, background maintenance tasks such as automatic backup can interfere with application installation, service initialization, database operations, and resource locking. For that reason, engineers typically disable automatic backup before beginning installation or deployment on the CSP OM portal. This is consistent with Huawei’s broader operation and maintenance logic, where management-plane activities on the CSP OM portal directly affect application deployment behavior. The material repeatedly uses the CSP OM portal as the control point for cluster and application configuration, for example when engineers need to view BMU-related service addresses through “Application Configuration > Configuration Management > Configuration > Application Name > Two-Node Cluster”

From an implementation perspective, installation requires a stable and uncontested environment. If an automatic backup starts during deployment, file operations, configuration updates, or service restarts may be interrupted, which can lead to incomplete installation or task failure. Therefore, disabling the automatic backup function before IVS installation is a valid preventive measure and should be regarded as a correct statement.

The correct answer is C because tripwire crossing detection is fundamentally based on analyzing the movement trajectory of an object relative to a predefined virtual line. In intelligent vision systems, the object is first detected, then tracked frame by frame, and its centroid positions are recorded to form a trajectory. The material explains that “A movement trajectory consists of positions of the centroid of a moving object in individual frames” and also states that “To accurately predict whether an object is likely to cross the tripwire, features need to be extracted from the object… Dynamic features: trajectory, speed, and direction. Tripwire crossing detection mainly involves the extraction of dynamic features of an object.”

This means the decisive event is whether the tracked path intersects the configured tripwire. Speed alone does not determine crossing, and simply being in motion is insufficient. Direction can be an additional filtering condition in some deployments, but the actual crossing judgment is established through trajectory analysis. Therefore, the system concludes that an object has crossed the tripwire when its motion trajectory intersects the tripwire line, making C the most accurate answer.

The physical design of a data center for intelligent vision systems involves strategic placement of network switches to optimize cabling and performance. Two common architectures are Top of Rack (TOR) and End of Row (EOR). In a TOR deployment, Top of Rack (TOR) switches are deployed on the top of each cabinet and used for communication between servers in each cabinet and the external network . This approach minimizes the length of copper cabling within the rack and simplifies the expansion of individual cabinets.

Conversely, the EOR architecture centralizes the switching infrastructure. In this setup, End of Row (EOR) switches are deployed in the last cabinet at each row, and servers in all cabinets at each row are connected to switches through horizontal cabling . While EOR can simplify management by centralizing hardware, it requires significant horizontal cabling across the row. Huawei’s IVS planning recommendations specify that the management port and service ports of hardware devices (like the Taishan 200) connect to these switches. Specifically, the "Management TOR" handles the management plane (often using CE5800 series), while the "Service TOR" handles the high-bandwidth 10 GE service plane (often using CE6800 series), with both eventually aggregating through the EOR switch to connect to the wider customer network.

The correct answer is C because the described method exactly matches the definition of horizontal projection used in license plate character area extraction. In license plate recognition, projection methods are commonly used to separate valid character regions from noise and borders. The material states that “Horizontal projection: The binary license plate image is horizontally projected along the Y axis to obtain the longest successive projection segment as the character area. Filter out horizontally successive black lines around the license plate.” This wording is essentially identical to the question, so the method can be identified directly.

From an image-processing perspective, horizontal projection analyzes the pixel distribution across rows to locate the effective vertical range of the character band. This helps remove irrelevant black border lines above and below the plate characters. By contrast, vertical projection is mainly used later to segment individual characters because spaces naturally exist between them. Binary processing is a preprocessing step, not the named segmentation method here, and direction division is not the correct technical term in this context. Therefore, the only correct choice is C. Horizontal projection .

The correct answer is A because video site planning follows a logical engineering sequence: first determine where the site should be deployed, then perform a detailed site survey , and finally complete device selection planning based on the confirmed environmental and construction conditions. The material first lists typical site selection targets such as “Road intersections and entrances and exits” and “Key areas in cities” , which clearly corresponds to site selection planning. It then moves into survey items such as “Environment survey” , “Power supply” , and “Construction conditions” , showing that the survey is performed after the preliminary site location is determined and before final device planning is completed

This sequence is consistent with actual project practice. A project team cannot choose appropriate poles, anti-corrosion levels, cameras, power schemes, or transmission methods until the physical environment has been checked. For example, the survey determines whether the site is near the sea, whether mains power is stable, and whether enough construction space is available. Those findings directly affect the final device model and solution design. Therefore, the correct process is video site selection planning → video site survey → video site device selection planning .

The correct answer is B . T-Shot is an imaging and exposure technology rather than a protocol, compression method, or storage function. The material explicitly states that “M-Q and X-H series omni-data structuring cameras support T-Shot snapshot engine” and further explains that “T-Shot, Huawei's patented exposure technology, enables optimal imaging of targets and vehicles at the same time”

This directly identifies both the nature and purpose of the technology.

From a technical perspective, T-Shot addresses a common problem in complex surveillance scenes where pedestrians, non-motor vehicles, and motor vehicles may appear simultaneously in a single frame but require different exposure treatment. Traditional exposure methods often fail to preserve all such objects properly in one image. T-Shot improves simultaneous target and vehicle imaging quality, which is especially important in mixed urban environments, campuses, and residential areas. Option A is incorrect because T-Shot is not related to video compression. Option C confuses it with an interconnection protocol such as ONVIF. Option D incorrectly describes a storage or indexing function. Therefore, the only correct choice is B .

The Huawei Intelligent Video Surveillance (IVS) platform is designed with a high degree of openness and compatibility, allowing it to manage a vast array of front-end devices from various third-party vendors. To facilitate this interoperability, the platform utilizes a specialized driver or plug-in architecture. While standard protocols like ONVIF, GB/T 28181, and SDKs provide a baseline for communication, many proprietary features and vendor-specific protocols require a dedicated access plug-in to be installed on the platform side.

These plug-ins act as a translation layer that maps the third-party camera's private commands and data structures to the IVS platform's unified internal management language. This is particularly important for synchronization functions and interconnection collection, which are often handled by the VDS (Video Data Service) component. By installing the correct vendor-specific plug-in, the platform can access advanced camera features such as PTZ control, alarm reporting, and parameter configuration that might not be fully supported by generic standards. This modular approach allows Huawei's intelligent vision system to remain flexible and future-proof, enabling rapid integration of new camera models and vendors without requiring a full system-wide firmware upgrade.

The correct answer is A. TRUE . License plate recognition cameras are suitable anywhere vehicles need to be identified, recorded, or controlled, provided that the road geometry and deployment conditions support proper capture. The material explains that “License plate is recognized when vehicle checkpoints capture passing vehicles and built-in algorithms extract license plate features” and further states that common checkpoints are installed on “sites like highways, toll stations and urban roads” to record passing vehicle information and capture full vehicle images . This directly confirms the suitability of highways and urban roads .

By extension, the same technical principle applies to campus driveways , because they are controlled vehicle entry and exit points where access recording, vehicle identity confirmation, and passage management are important. In practice, campus entrances behave similarly to micro-checkpoint scenarios, where the objective is to recognize plates and support vehicle management. As long as the installation angle, lighting, lane width, and capture distance are appropriate, LPR cameras can be deployed effectively in those locations. Therefore, the statement is consistent with the deployment logic of the material, and the answer is true.

The correct answer is C because the Kunpeng processor is characterized by ARM-based RISC design, multi-core capability, low power consumption, and high integration, but not by a closed architecture . The material describes Kunpeng’s strengths by stating that “The ARM architecture is used so that the same function performance occupies a smaller area of the chip, consumes less power, and are highly integrated. More hardware CPU cores are provided for better concurrent processing” and further notes that “The RISC instruction set is used. The instruction length is fixed, the addressing mode is flexible and simple, and the execution efficiency is high” . These statements directly support options A, B, and D .

From an engineering perspective, ARM-based processors are known for compact instruction design, strong concurrency through many CPU cores, and high performance per watt. Those are exactly the attributes highlighted here. By contrast, “closed architecture” is not presented as a Kunpeng feature in the training material and does not align with Huawei’s ecosystem positioning, which emphasizes compatibility across multiple operating systems and application scenarios from IoT to cloud. Therefore, C is the only option that does not describe the Kunpeng processor.

The correct answer is B because switching the secondary stream type is a stream configuration task, not an image-adjustment operation in the PTZ dome camera web interface. During image adjustment, the operator typically works with live-view and framing tools, such as directional control, local inspection, and capture assistance. That is why operations such as using a virtual joystick to move the PTZ direction, taking snapshots , and performing ePTZ for local image inspection fit naturally into image adjustment behavior.

The broader training content confirms that PTZ control belongs to live-view operation, stating that users can “perform PTZ controls … for example, control the PTZ direction, set PTZ preset positions, and set the home position” . That supports directional adjustment as a valid operation. A snapshot is also a live-view support function, while ePTZ is commonly used for image observation and local enlargement. However, secondary stream type belongs to video stream configuration, such as choosing or modifying stream properties, and is not part of direct image-adjustment handling. Therefore, the option that cannot be performed in image adjustment is B .

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 correct answer is B. FALSE . The material clearly presents the PowerCube 500 as an integrated power and site support solution , not as a video transmission platform. It states that “Huawei PowerCube 500 is widely used in Safe City and Smart City solutions to house and supply power to data transmission devices, network devices, and cameras” and that “The system adopts modular design based on the integrated platform, and supports high-performance lithium batteries and intelligent NMS”

This shows that the intelligent NMS is used for site equipment and power management , such as monitoring operating state, alarms, and module conditions. The same section lists indicators for board and service status, including hardware fault, service alarm, and power-supply conditions, which supports the fault-management role of the NMS . However, the statement becomes false because it adds “real-time video data” reporting to the upper-layer NMS. PowerCube does not function as a video analytics or live video reporting platform. It supports and powers video devices, but the video streams themselves belong to camera and network service domains, not PowerCube’s NMS reporting scope. Therefore, the statement is false.
