If you’re in the security field, you’ve probably heard terms like “Starlight,” “Full Color,” and “Black Light” used to describe cameras. But what do they really mean? In simple terms, these names all refer to technologies that help cameras “see” clearly at night or in low light. When there’s not enough light, cameras generally rely on two approaches to capture usable images: improving the camera’s own ability to capture light, or adding supplemental lighting.

The technical trajectory of security cameras was not an overnight success but a cross-disciplinary evolution spanning two centuries. Its roots can be traced back to the late 19th century with the first attempts to capture continuous dynamic images. In 1870, English inventor Wordsworth Donisthorpe patented the "kinesigraph," a moving picture camera designed to take a series of photos at set intervals to capture movement. In 1889, Donisthorpe and Louis Le Prince further refined film cameras and projection technology; Le Prince even developed a 16-lens camera, which, while more of an experimental tool at the time, laid the physical foundation for continuous monitoring in specific spaces.
