The Radiometric All-Sky Infrared Camera (RASICAM) has been operating on Cerro Tololo for over two years looking for clouds in the 10 to 12 micron IR band. Every 90 seconds each night RASICAM collects an integrated image of sky conditions and reports them to the Blanco telescope control system (TCS) to be shared with other instruments. We report on the RASICAM design, calibration and performance of the system. Additionally, correlation with conditions as observed in the Dark Energy Camera (DECam) will be presented.
