Abstract
An inter-digital capacitive sensor and control system are used to distinguish between rain, ice, dirt and debris on the outer lens surface of a surveillance camera. The electrodes of the capacitive sensor are made from a conductive coating such as printed epoxy or a transparent conductive oxide, that is directly deposited onto the inner surface of the lens. A defroster is spaced radially-outward from the capacitive sensor and is formed by metal deposition directly on the substrate surface.
