H12-521_V1.0 Exam Dumps : HCIP-Intelligent Vision V1.0

The correct answer is B . The material defines the strobe light as a lighting compensation device, stating that “Strobe light: provides light compensation at night to clearly capture license plates and pedestrians” . This directly shows that the purpose of the strobe light is to improve scene illumination so that important visual targets can be captured more clearly, especially in low-light conditions. That function most closely matches option B .

From an engineering standpoint, a strobe light is used to enhance the effective brightness of the monitored area and improve the visibility of vehicles, license plates, and other targets in both live viewing and snapshot capture. The installation notes further mention that the strobe light should be angled properly relative to the lane to avoid overexposure of license plates caused by direct illumination , which confirms that its role is optical illumination rather than sensing or speed detection. Option A is more consistent with a flash light , because the material states that “Flash light: provides strong light compensation to clearly capture targets and vehicle interiors” . Options C and D describe sensor and radar-related functions, not strobe light behavior.

The correct answer is D because the iris directly controls the amount of light entering the lens, which has the most immediate effect on image brightness. When the iris opening is enlarged, more light reaches the image sensor, and the captured image becomes brighter. This makes iris adjustment the preferred action when the goal is simply to improve overall brightness. By contrast, resolution affects image detail, not light intake. Angle of view changes scene coverage, not exposure level. Focal length changes magnification and framing, but it does not function as the primary exposure control in this context.

This aligns with the exposure-centered logic emphasized throughout the training material, where Huawei highlights advanced imaging control and notes that “T-Shot, Huawei’s patented exposure technology, enables optimal imaging of targets and vehicles at the same time” and that traditional exposure methods cannot properly expose different targets in one image . In practical camera operation, brightness problems are first treated as an exposure issue, and among the listed options, the iris is the only parameter that directly regulates exposure by controlling incoming light.

The correct answer is B because high-altitude observation requires long-distance scene coverage, flexible viewing angles, and the ability to zoom, track, and inspect targets over a wide area. Among the listed options, a 4K HD PTZ dome camera is the most suitable for this role. The material repeatedly associates PTZ cameras with dynamic scene observation and motion-based analysis. For example, it explains optical-flow continuity using “a PTZ dome camera, in its course of rotation” , which reflects the PTZ camera’s ability to scan large spaces and continuously adjust its observation direction . In addition, the site installation material explicitly supports installation of “one PTZ dome camera” on the pole solution, indicating its intended use in broader-area outdoor observation scenarios

From a technical standpoint, fixed dome and bullet cameras are more appropriate for fixed-angle monitoring, entrance observation, or lane-style capture. A box camera can be used in specialized setups, but it does not inherently provide the integrated pan-tilt-zoom flexibility needed for elevated monitoring. A 4K PTZ dome combines high resolution with zoom and directional control, making it the strongest option for long-range and high-position observation tasks.
