\"NVR<\/a><\/p>\n

Il DVR<\/strong> (Digital Video Recorder) \u00e8 l\u2019acronimo di videoregistratore digitale e costituisce una parte fondamentale di un sistema di videosorveglianza.<\/h2>\n

La sua funzione \u00e8 quella di gestire i video trasmessi dalle telecamere permettendone il controllo e l\u2019archiviazione ai fini dell\u2019individuazione dell\u2019evento d\u2019effrazione.
\nOltre ai tradizionali DVR possiamo trovare anche i pi\u00f9 moderni NVR<\/strong>, che sta per Network Video Recorder.
\nMa vediamo quali sono le differenze<\/span>, considerando soprattutto che la scelta degli uni o degli altri non riguarder\u00e0 tanto la loro capacit\u00e0 di memorizzazione, quanto il diverso tipo di impianto di videosorveglianza che vogliamo installare.
\nMentre il Digital Video Recorder comprime in maniera digitale i video e li conserva in un hard disk, il Network Video Recorder, come s\u2019intende dal nome stesso, lavora direttamente in rete.<\/p>\n

L\u2019NVR presenta un vantaggio importante<\/strong> rispetto al pi\u00f9 tradizionale videoregistratore: quest\u2019ultimo infatti registra i dati su un HD e nel caso in cui questo si guastasse tutti i dati andrebbero persi, semprech\u00e9 non sia predisposto un backup istantaneo dei video su altro HD di sicurezza.<\/p>\n

Nel caso invece di un NVR, potendo lavorare in modalit\u00e0 \u201cmirror<\/strong>\u201d, i file potranno essere duplicati istantaneamente su altri HD presenti in rete o essere immagazzinati su di un server.<\/p>\n

Un sistema NVR utilizzer\u00e0 esclusivamente telecamere IP<\/strong> (ossia in rete LAN, WI-FI, o Internet) essendo le uniche che possono essere messe in rete, pertanto avr\u00e0 un costo maggiore rispetto ad un comune DVR che viceversa potr\u00e0 utilizzare anche delle normali telecamere con collegamento coassiale. Se con un sistema DVR la spesa dei dispositivi risulta essere minore, occorre per\u00f2 considerare l\u2019ulteriore spesa dell\u2019installazione filare dell\u2019impianto.<\/p>\n

Pertanto se gi\u00e0 abbiamo un vecchio impianto di videosorveglianza<\/strong> sar\u00e0 preferibile utilizzare il tradizionale DVR sfruttando i collegamenti esistenti, nel caso invece in cui non esista un preesistente impianto da sfruttare, o non si intendano fare opere murarie, o tirare canaline sar\u00e0 certamente preferibile utilizzare i nuovi NVR.<\/p>\n","protected":false},"excerpt":{"rendered":"
