Abstract

L'invention concerne une caméra et un système de TVSF. Les systèmes TVSF existants comportent plusieurs caméras qui surveillent des bureaux, des commerces ou des lieux publics. Il existe un risque élevé qu'un incident ou un événement détecté ne soit pas affiché dans le local de contrôle au moment où se produit l'incident. Dans un mode de réalisation préféré, l'invention concerne un système TVSF dans lequel une caméra est munie d'un dispositif qui permet d'obtenir des informations relatives au déplacement d'un objet dans le champ visuel de la caméra. Un dispositif de traitement détermine si ces informations dépassent un seuil prédéterminé et commute le cas échéant les moniteurs sur la réception de ladite (desdites) caméra(s). L'avantage de l'invention est de pouvoir afficher automatiquement les événements visualisés, dès l'instant où ils se produisent.
