In a surveillance context, what is meant by the term "resolution"?

In a surveillance context, the term "resolution" refers to the clarity and detail of the captured video image. Resolution indicates how much detail the camera can record, which is typically measured in pixels. Higher resolution means more pixels in the image, translating to sharper and clearer pictures. This is crucial in surveillance applications, as it allows for the identification of people, objects, and events with greater accuracy.

For example, a camera with high resolution can capture fine details such as facial features or license plates, which are essential for effective monitoring and reporting. This level of detail can significantly impact the effectiveness of security systems and the ability to gather usable evidence from video footage. Hence, resolution is a critical factor in the quality and effectiveness of surveillance cameras.
