Video surveillance systems for use in security applications - Part 2-32: Recording control and replay based on web services

This Standard specifies the web service interface for the configuration of the recording of video, audio and metadata. Additionally, associated events are defined. Clause 4 provides a definition of the storage model this document is based on. Web service usage is outside the scope of this document. Please refer to the IEC 60839-11- 31 for more information.

Systèmes de vidéosurveillance destinés à être utilisés dans les applications de sécurité - Partie 2-32: Contrôle d'enregistrement et lecture en fonction des services Web

l'IEC 62676-2-32:2019 spécifie l'interface de services web pour la configuration de l'enregistrement des données vidéo et audio, ainsi que des métadonnées. De plus, les événements associés sont définis. L'utilisation des services web ne relève pas du domaine d'application du présent document. Se reporter à l'IEC 60839-11-31 pour de plus amples informations. Cette première édition, conjointement avec l'IEC 60839-11-31 et l'IEC 62676-2-31, annule et remplace l'IEC 62676-2-3:2013. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 62676‑2-3:2013: a) ajout d'un format de fichiers d'exportation.

Video nadzorni sistemi za varnostne aplikacije - 2-32. del: Kontrola snemanja in predvajanje na podlagi mrežnih servisov

Ta standard določa vmesnik spletne storitve za konfiguracijo snemanja videa, zvoka in metapodatkov. Poleg tega so opredeljeni tudi povezani dogodki. Točka 4 določa definicijo modela shranjevanja, na katerem temelji ta dokument. Uporaba spletne storitve ne spada na področje uporabe tega dokumenta. Za več informacij glej standard IEC 60839-11- 31.

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

misi
