This whitepaper explains how infrared (IR) technology enables effective surveillance in low-light and no-light environments by allowing cameras to capture clear images without visible illumination. Day-and-night cameras switch automatically between color and grayscale modes depending on lighting conditions, while IR illumination ensures consistent visibility. Advanced solutions like OptimizedIR combine intelligent camera control with efficient LED illumination to deliver even lighting and extended range. The paper also distinguishes IR from thermal imaging, highlighting their different applications. By leveraging IR technology, organizations can maintain reliable, high-quality surveillance around the clock, improving security outcomes in challenging lighting conditions.
