Further, by arranging the light emitted from the light source unit 62 to pass through the filter unit 223 and irradiate the subject, the imaging unit 6b can accurately capture the subject by suppressing the luminance. Is possible.

Abstract

L'objectif de la présente invention est de fournir un dispositif de surveillance A ayant moins tendance à susciter une gêne, la peur ou la douleur chez une personne devant être surveillée et pouvant détecter avec précision l'état de la personne surveillée. Pour ce faire, le dispositif de surveillance A est agencé de telle sorte que la distance entre une partie réglage d'onde radio 32, pour augmenter la directivité des ondes radio émises par une partie émetteur-récepteur à ondes radio et un couvercle 22 recouvrant la partie émetteur-récepteur à ondes radio et la partie réglage d'ondes radio tout en permettant aux ondes radio de passer à travers celui-ci, soit un nombre entier, multiple de la moitié de la longueur d'onde des ondes radio.
