Abstract: A system and method for detecting delivery items includes a hardware processor that is operably connected to a light detector and a camera positioned at a sensing location along a moving surface that moves a delivery item. The processor may be configured to perform operations that include receiving a light status signal from the light detector, the light status signal having a first state when a light beam directed across the moving surface is detected at the light detector, which indicates absence of the delivery item, and a second state when the light beam is not detected at the light detector, which indicates presence of the delivery item, receiving image data from the camera, which includes images at the sensing location, and modifying the light status signal based on the image data when the light status signal and the image data disagree on the number of delivery items.
