The working-age population is decreasing amid the declining birth rate and rapidly aging population. Against this backdrop, there is an increasing need for unmanned convenience stores to reduce personnel expenses and to resolve labor shortages. It is possible to accurately capture the movements of customers from when they enter a store to when they leave and to track them from all viewpoints in unmanned stores by installing cameras and sensors in place of people. For example, such cameras and sensors can recognize when products have been taken from shelves by customers, and unmanned payment starts when the customer proceeds to the cash register.
At the same time, to realize such unmanned stores, it is necessary to install AI security cameras and large-capacity data communication devices. In other words, there was an issue of securing the electric power infrastructure to transmit electricity to those devices. Moreover, by incorporating AI into security cameras, there were other issues such as an increase in power consumption and the need for gigabit communication that allows for the exchange of large amounts of data.
