We have developed a system that automatically selects images from particular cameras based on RFID (radio frequency identification) tags that identify individual persons or objects, thus enabling each user to receive desired images via IP networks. For exampe, if an RFID tag is inserted in the nametag of a kindergarten child and several cameras are installed in the kindergarten, the system automatically switches the transmitted images according to the child's movements so that the parents can watch their own child from home or the office.
