Video surveillance systems for use in security applications - Part 4: Application guidelines

IEC 62676-4:2014 gives recommendations and requirements for the selection, planning, installation, commissioning, maintaining and testing video surveillance systems (VSS) comprising of image capture device(s), interconnection(s) and image handling device(s), for use in security applications. The objectives of this part of IEC 62676 are to:
- provide a framework to assist customers, installers and users in establishing their requirements;
- assist specifiers and users in determining the appropriate equipment required for a given application;
- provide means of evaluating objectively the performance of the VSS.

Systèmes de vidéosurveillance destinés à être utilisés dans les applications de sécurité - Partie 4: Directives d'application

L'IEC 62676-4:2014 fournit des recommandations et des exigences pour choisir, planifier, installer, mettre en service, entretenir et soumettre à essai des systèmes de vidéosurveillance (VSS) comprenant un(des) dispositif(s) de capture d'images, d'interconnexion et de traitement d'images, destiné(s) à être utilisé(s) dans des applications de sécurité. Les buts visés par la présente partie de l'IEC 62676 sont les suivants:
- fournir un cadre pour aider les acheteurs, les installateurs et les utilisateurs à établir leurs exigences de fonctionnement;
- aider les rédacteurs de spécifications et les utilisateurs en déterminant le matériel approprié, nécessaire à une application donnée;
- fournir un moyen d'évaluer objectivement les performances du VSS.

Part 4: Application guidelines
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas,
