Infrared (IR) security cameras can capture black-and-white images even when there is little visible light. This technology is crucial in enhancing visibility and capturing images in low-light or nighttime conditions.
IR security cameras are equipped with infrared LEDs that emit infrared illumination. This illumination can then convert the reflected IR light to a grayscale image visible to the human eye, which can then be displayed or recorded for surveillance purposes.
By leveraging IR technology, security cameras can effectively monitor areas with little or no available light, such as nighttime scenes or dimly lit alleys and rooms. This enables round-the-clock surveillance and enhances the overall security of a location by providing visibility in challenging lighting conditions.
