Diese Europäische Norm ist nicht auf Sicherheitssysteme, Geräte gegen Diebstahl, gegen Überfall und CCTV-Überwachungsanlagen, sowie Zugangskontrollsysteme bei Sicherheitsanwendungen anwendbar. Diese Europäische Norm beschreibt folgende Systemanforderungen: – Elektrische Sicherheit und EMV Kompatibilität; – Audiospezifikationen; – Videospezifikationen; – Umweltbedingungen; – Vandalensicherheit. Geräte die in anderen Systemen eingesetzt werden, müssen die Anforderungen dieser Systeme einhalten (z. B. Telefonanlagen oder Alarmanlagen).
Matériel destiné à être utilisé dans les systèmes de portiers électroniques audio et vidéo
La présente Norme Européenne spécifie les exigences pour le matériel installé dans les systèmes de portiers électroniques audio et vidéo. La présente Norme Européenne ne s’applique pas aux systèmes de sécurité, aux dispositifs antivol, aux dispositifs anti-agression, aux systèmes de surveillance par télévision en circuit fermé (CCTV; en anglais closed-circuit television) et aux systèmes de contrôle d’accès à usage dans les applications de sécurité. La présente Norme Européenne définit les exigences de systèmes suivantes: – conformité en matière de sécurité et de compatibilité électromagnétique (CEM); – spécifications audio; – spécifications vidéo; – conditions d’environnement; – résistance au vandalisme. Les dispositifs intégrés dans d'autres systèmes doivent également être conformes aux exigences de ces systèmes (par exemple réseau téléphonique ou systèmes d'alarme).
