Abstract
Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a dimmer device including a driver, and a controller communicatively coupled to the driver and to a monitor device. The monitor device can include a camera and is configured to take a plurality of images of the illumination load. The controller provides a control signal that indicates to the driver to adjust power supplied to an illumination load. The control signal is provided in response to a determination that a performance of the illumination load fails to satisfy a predetermined performance indicator. The performance of the illumination load is determined based on information related to the plurality of images of the illumination load taken by the camera of the monitor device. The controller can adjust a dimming level of the illumination load by providing the control signal to the driver.
