Multi-factor-based Motion Detection for Server Rack Doors Left Open

It is crucial to ensure that server rack doors are properly closed in data centers in order to prevent serious dangers caused by the doors suddenly opening in disasters and causing accidents that hurt maintenance workers and damage facilities. In this paper, we propose multi-factor-based motion detection for server rack doors that have been left open. Our approach recognizes the status of server rack doors on the basis of maintenance workers' motion and prevents a worker from forgetting to close the doors without using any additional devices, only smartphones, which maintenance engineers already carry for work.
