Video surveillance systems for use in security applications - Part 5: Data specifications and image quality performance for camera devices

This part of IEC 62676 defines recommendations and requirements for representation and
measuring methods of performance values to be described in materials such as instruction
manuals, brochures and specifications of video surveillance camera equipment.
This document consists of two parts. The first part is requirements for description of video
surveillance camera specification items. The second part is requirements for measurement
methods of video surveillance camera specification items.
A video surveillance camera's output can be analogue (e.g. composite video such as NTSC or
PAL) or digital (e.g. compressed network output, uncompressed SDI (serial digital output),
etc.).

Systèmes de vidéosurveillance destinés à être utilisés dans les applications de sécurité - Partie 5: Spécifications des données et performances de la qualité d'image pour les dispositifs de caméra

L'IEC 62676-5:2018 définit des recommandations et des exigences concernant les méthodes de représentation et de mesure des valeurs de performances à décrire dans des supports tels que manuels d'instruction, brochures et spécifications de caméras de vidéosurveillance. La première partie de ce document concerne les exigences de description des éléments de spécification des caméras de vidéosurveillance. La seconde partie concerne les exigences de méthodes de mesure des éléments de spécification des caméras de vidéosurveillance.

Video nadzorni sistemi za varnostne aplikacije - 5. del: Specifikacije podatkov in kakovost slike kamer

Ta del standarda IEC 62676 opredeljuje priporočila in zahteve za metode predstavitve ter merjenja vrednosti lastnosti, ki jih je treba opisati v gradivu, kot so navodila za uporabo, brošure in specifikacije, namenjenem za videonadzorne kamere.
Ta dokument je sestavljen iz dveh delov. V prvem delu so podane zahteve za opis elementov specifikacij videonadzornih kamer, v drugem delu pa so podane zahteve za metode merjenja elementov specifikacij videonadzornih kamer.
Izhod nadzorne kamere je lahko analogen (npr. sestavljeni video signal, kot je NTSC ali PAL) ali digitalen (npr. stisnjeni omrežni izhod, nestisnjeni SDI (serijski digitalni izhod) itd.).
