What does the term "resolution" refer to in CCTV cameras?

• A. The distance video can be transmitted
• B. The amount of storage needed for footage
• C. The clarity and detail of the video image
• D. The speed of video playback

Answer: (C)

Resolution in CCTV cameras refers to the clarity and detail of the video image produced by the camera. It indicates the amount of detail that can be captured and displayed, which is usually measured in pixels. A higher resolution means that more pixels are used in the image, resulting in finer detail and a clearer picture, which is crucial for identifying objects or faces in surveillance footage. The other options, while related to technical aspects of CCTV systems, do not accurately define resolution. The distance video can be transmitted pertains to transmission range rather than image quality. The amount of storage needed for footage relates to file sizes, which can be influenced by resolution but does not define it. The speed of video playback concerns how quickly the video runs, which is independent of the video's resolution. Therefore, the correct understanding of resolution directly aligns with the clarity and detail seen in CCTV images.
