Why do strong spotlights or sunlight in the classroom/meeting room cause the whiteboard to drop touch signals or malfunction?
IR whiteboards operate by emitting and detecting invisible infrared light grids. If the device is installed next to a window with direct sunlight, or directly under high-power halogen spotlights, the intense ambient IR light can saturate the optical receivers around the frame, leading to dead spots or erratic tracking.
Mitigation: Avoid placing the whiteboard in direct sunlight (use blinds if necessary) and adjust the angle of overhead spotlights to ensure they do not shine directly into the grooved inner bezels of the whiteboard frame.
