Utilizata si in senzorii de imagine al camerelor Hikvision, tehnologia CMOS ajuta la captarea imaginilor la o calitate superioara. Printre caracteristicile importante ale dispozitivelor CMOS sunt imunitatea ridicata la zgomot si consum de energie redus. Un nou standard este necesar pentru a micsora dimensiunile fisierelor pe masura ce tehnologia avanseaza. Aici intra in actiune standardul H. 265+ . Acest standard este conceput sa utilizeze o latime de banda mult mai mica multumita tehnicilor de encoding avansate dar si un model de encoding/decoding mai sofisticat. Modalitatea foarte usoara de configurare a echipamentului permite vizualizarea chiar si de la distanta a camerelor. Aplicatia Hik-Connect va pune la dispozitie, printr-o simpla scanare a codului QR posibilitatea de a monitoriza zona dorita, oricand si oriunde Functia AcuSense filtreaza si elimina alarmele false (pasari, frunze, ploaie, lumina) cu o acuratete de peste 90%. IP O camera IP este o camera video digitala in retea, care transmite datele printr-o legatura fast ethernet link. Camerele IP (deasemenea numite camere de retea ) sunt cel mai des folosite pentru supravegherea video, o versiune digitala si de retea a televiziunii cu circuit inchis (CCTV). Beneficiile camerei IP fata de tehnologia analogical : - Administrare de la distanta din orice locatie; - Zoom digital; - Capacitate de a trimite cu usurinta imagini si video oriunde , cu o conexiune la internet; - Scanare progresiva, care permite imagini de o calitate mai buna extrase din inregistrare, in special pentru tintele mobile; - Numarul de cadre reglabil pentru a atinge specificatiile cerute; - Capacitatea de a trimite semnale de alerta in cazul in care este detectata activitate suspecta; - Cerinte de cablare mai mici. Automatic Gain Control - AGC AGC - este o functie realizata de camera de supraveghere video, care are rolul de a mari/micsora calitatea imaginilor surprinse in conditii de iluminat scazut/ridicat. Daca semnalul este prea slab, datorita scaderii iluminatului, atunci acest circuit amplifica semnalul din ce in ce mai mult. Daca semnalul este adecvat, circuitul responsabil cu functia AGC nu va aplica nici o amplificare. Iar daca lumina este prea puternica acest circuit va diminua semnalul video. ROI Codec Caracteristica care ofera posibilitatea de a crea o zona definita ROI (Region of Interes), astfel incat imginea va cuprinde mai multe detalii si o calitate mai buna la acelasi bit rate. Latimea de banda si dimensiunea inregistrarii sunt si ele diminuate, deoarece zonele nedefinite ca ROI vor capta imagini la o calitate mai scazuta. Line crossing Aceasta functie poate detecta obiecte, persoane sau masini ce depasesc o linie virtuala predefinita. Reprezinta o solutie ideala pentru monitorizarea intrarilor, a parcarilor sau alte zone delimitate. 3D- DNR DNR este o functie care reduce zgomotul de imagine , in scopul de a imbunatati calitatea imaginii aparatului. In special , se reduce zgomotul care este generat in conditii de luminozitate slaba. 3D se refera la trei dimensiuni si incorporate in 3D DNR este un circuit de reducere a zgomotului digital, capabil de a reducezgomotul de imagine si de a imbunatati esecul amestecat de culori si contactul de culori. Wide Dynamic Range – WDR Este o tehnologie utilizata de camerele de supraveghere video CCTV, cu scopul de a echilibra imaginile video care au o gama dinamica mare. Aceasta este o caracteristica care confera camerei, posibilitatea, de a aplica intensitati separate ale luminii pentru aceeasi imagine. Aceasta functie este ideala pentru imagini care cuprind atat zone luminate cat si zone intunecate. Functia ICR – infrared cut filter removal Pentru modul de zi, are un efect de interferenta asupra calitatii imaginii camerei, ceea ce duce la alterarea culorilor si a contrastului. Pentru modul de noapte, lumina infrarosie este utilizata pentru a atinge detaliile imaginii in intuneric sau cu lumina slaba. SD card Scapa de grija instalatiilor complexe , de amalgamul de cabluri si echipamente grele si costisitoare, deoarece acum poti inregistra si stoca imaginile pe propriul card SD pe care il conectezi direct la camera. Datorita standardului ONVIF incorporat, camera poate fi asociata si cu NVR-urile altor producatori. Power over Ethernet – PoE Reprezinta modalitatea de alimentare a camerelor sau a altor echipamente IP, prin intermediul cablului de retea. Implementarea retelei se rezuma la un singur cablu, prin care este transmis semnalul de date cat si alimentarea echipamentului. Prin intermediul PoE, instalarea sistemelor de supraveghere devine mult mai simpla, mai sigura si mai putin costisitoare. IK10 Caracteristica IK10 este un standard ce arata ca o camera poate suporta o energie de impact de pana la 20J. Toate camerele Speed Dome Smart PTZ de la HIKVISION pot fi echipate cu carcasa IK10. Wide temperature Domeniul larg de functionare al camerei, ii permite acesteia sa functioneze intr-un mediu cu temperaturi cuprinse intre -40°C si +60°C si cu umiditate de pana la 90%.
