A system, method, and device for monitoring the dispensing of liquids, in particular, beverages dispensed at a bar or restaurant is disclosed. The device attaches to the exterior of a container and detects dispensing events by sensing tilt or motion of the container, which could include a bottle or a handle. The system includes an electronic sensor device, data receiver, personal computer, bottle opener/camera system, bar code scanner, point of sale, bar camera, network, Web server, and paging system. The method automatically detects and monitors dispensing events, including detecting the type and amount of liquid, reconciling dispensing events with register ring-ups, recording information, saving video specific to the dispensing event, and sending a page indicating anomalies.
