Security and nursing care services require an accurate understanding of the condition of people and objects. For this reason, these services use IoT (Internet of Things) devices equipped with sensors and communication devices. As these IoT devices are evolving, the amount of data sent by IoT devices may increase. In addition, the increasing demand for IoT devices is expected to lead to an increase in users of the data.
A common way to meet this requirement is for IoT devices to convert the data and send it individually. However, as the number of data destinations increase, the amount of communication data also increases, which limits the number of services that can use the IoT device data.
To solve this problem, SECOM Intelligent Systems Laboratory has started joint research with NTT Network Technology Laboratories, to develop "technology that converts and transmits large amounts of data sent by IoT devices according to the service situation."
The data needed for security and nursing care services are created in everyday life, and many device are used near the point of occurrence. Therefore, we propose installing a server in a central office near the IoT devices to convert and transmit the data, improving the network usage efficiency in places where data is heavily used.
As in the use case above, this technology transforms and transmits the IoT device data according to its purpose. Specifically, it consists of the following functions.
These functions ensure that high-quality video data is transmitted to the data center, and lightweight video data can be delivered to staff around the site in real time. SECOM Intelligent Systems Laboratory believes that this technology can contribute to the increase in the number of services that can simultaneously use IoT devices and for staff members to share information and respond correctly.
