The SIR-4250 is an indoor camera with a 3.8 ~ 9.5mm V/F AI lens and IR illuminator all in one package. During daytime operation, the camera produces crisp 520TV line resolution color images. At night, the camera switches to black and white mode, removes the IR cut filter, and illuminates the scene up to 16M (52.5 ft) away without any added lighting. This makes it the ideal solution for applications such as night clubs or sleep centers.
