Supraveghere Video

Televiziune cu circuit închis (CCTV - din engleză (closed-circuit television)), de asemenea, cunoscut sub numele de supraveghere video, este utilizarea de camere video pentru a transmite un semnal la un anumit loc, pe un set limitat de monitoare. Aceasta diferă de la televiziune în care semnalul nu este transmis în mod deschis, deși se poate angaja punct la punct (P2P), punct la multipunct (P2MP), sau ochiuri cu fir sau legături fără fir. Deși aproape toate camerele video se încadrează în această definiție, termenul este cel mai adesea aplicat la cele utilizate pentru supraveghere în zonele în care ar putea avea nevoie de monitorizare, cum ar fi baruri, bănci, cazinouri, școli, hoteluri, aeroporturi, spitale, restaurante, instalații militare, magazine și alte zone unde este necesară securitatea. Video-telefonia rareori este numită "CCTV", dar utilizarea de video în învățământul la distanță, în cazul în care este un instrument important, este de multe ori numită așa.

Supravegherea publică folosind CCTV este comună în multe zone din întreaga lume. În ultimii ani, utilizarea de camere video purtate pe corp a fost introdusă ca o nouă formă de supraveghere. Supravegherea video a generat o dezbatere semnificativă privind echilibrarea utilizării sale cu dreptul persoanelor la viață privată, chiar și atunci când se află în public.

În instalațiile industriale, echipamentele CCTV pot fi folosite pentru a observa părți ale unui proces de la o cameră de control centrală, de exemplu, atunci când mediul nu este potrivit pentru om. Sistemele CCTV pot funcționa în mod continuu sau numai după cum este necesar pentru a monitoriza un anumit eveniment. O formă mai avansată de CCTV, utilizarea înregistratoarelor video digitale (Dvr-uri), poate oferi înregistrare, pentru mulți ani, cu o varietate de calitate și performanță și caracteristici suplimentare (cum ar fi de detectarea mișcării și alerte e-mail). Mai recent, camere IP descentralizate, unele echipate cu senzori de imagine, suportă înregistrarea direct la dispozitivele se stocare atașate la rețea sau la memoria flash internă, asigurând astfel o funcționare complet autonomă.

Există aproximativ 350 de milioane de camere de supraveghere la nivel mondial începând din 2016. Aproximativ 65% din aceste camere sunt instalate în Asia. Creșterea televiziunii cu circuit închis a încetinit în ultimii ani.
