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

The term "resolution" in CCTV systems specifically refers to the clarity and detail of the image produced by the camera. Higher resolution means that the camera can capture more detail, which results in a clearer and more defined image. This is measured in pixels; for example, a 1080p camera has a resolution of 1920x1080 pixels, which allows for a more detailed and crisp image compared to lower resolutions.

Understanding resolution is crucial in CCTV systems as it directly impacts the effectiveness of surveillance. Higher resolution can improve the ability to identify faces, license plates, and other important details in monitoring scenarios, making it vital for security purposes.
