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 .
