ROOM ENTRY/EXIT DETECTION DEVICE ROOM ENTRY/EXIT DETECTION METHOD AND COMPUTER-READABLE RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON

摘要

The person detector 211 detects a person in an area in contact with one side of the door. The open / close detector 212 detects whether the door is in an open state or in a closed state. When the door detected by the open / close detector 212 is switched from the closed state to the open state, the open state person detection information recorder 213 records whether or not the human detector 211 is detecting a person. When the state of the door detected by the open / close detector 212 is switched from the open state to the closed state, the closed state human detection information recorder 214 records whether or not the human detector 211 is detecting a person. The entrance / exit detector 215 detects that there has been an entrance and a departure based on the contents recorded by the open state people detection information recorder 213 and the closed state people detection information recorder 214.
