In MOST cases, higher signal-to-noise ratios are associated with ______.

Higher signal-to-noise ratios are indicative of clearer and higher quality images in CCTV systems. A signal-to-noise ratio (SNR) measures the level of a desired signal relative to the level of background noise. When the SNR is high, it means that the signal (the actual image being captured) is much stronger compared to any interference or noise, which allows for better visual clarity and detail.

In practical terms, a higher SNR leads to a decrease in distortion and artifacts in the image, which means that when you review the footage, you can see clearer outlines, colors, and finer details. This is essential in security applications where identifying individuals or objects is critical.

Lower signal-to-noise ratios, on the other hand, can lead to various visual issues such as graininess, distortion, or shadowy footage, which diminish the overall quality of the images captured by the CCTV system. This highlights the importance of maintaining a good SNR in the installation and operation of CCTV systems for effective surveillance.
