CRI, or Color Rendition Index, measures how accurately a light source displays colors compared to natural light. The scale ranges from 0 to 100, with higher values indicating better color reproduction.
In surveillance systems, CRI affects how clearly cameras capture colors under artificial lighting. For example, a low CRI may distort the appearance of clothing or objects, making identification harder.
Choosing lights with a high CRI improves image quality and color accuracy. This is especially important in environments where true color representation supports security or evidence review.
While CRI is not the only factor in lighting design, it plays a key role in enhancing visibility and detail in camera footage.
