What functionality does OptimizedIR provide in a surveillance camera?

OptimizedIR is a feature in surveillance cameras designed to enhance the effectiveness of infrared illumination. Its primary function is to automatically adjust the angle of illumination based on the zoom level of the camera. This means that as the camera zooms in on a subject, the infrared light is also focused more tightly on that area, ensuring clearer images in low-light conditions. This adaptive capability is crucial for maintaining image quality and clarity, allowing the camera to capture fine details even in complete darkness.

Utilizing OptimizedIR helps to ensure that infrared lighting is not wasted on areas that are not under surveillance, promoting more efficient illumination where it's needed most. This feature effectively enhances the camera's performance in various lighting conditions, making it an important tool for ensuring reliable surveillance.
