Tehnologia CMOS 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 redus de energie Functia AcuSense filtreaza si elimina alarmele false (pasari, frunze, ploaie, lumina) cu o acuratete de peste 90%. 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. Full HD Nu lasa nici un detaliu sa treaca neobservat. Cu tehnologia HD poti surprinde imagini de o calitate mai buna, cu pana la 5 ori mai detaliate decat standardul SD. Deasemeni, suprafata care va fi acoperita va fi mult mai mare. 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 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. Digital Noise Reduction – DNR Functia DNR elimina "zgomotul" din imagini, generand astfel o imagine distincta si clara. Sunt eliminati pixelii nedoriti din imagine. Utilizand un filtru de reducere a zgomotului 2D pentru obiectele in miscare si un filtru adaptiv 3D de reducere a "zgomotului" pentru obiectele fixe. Ca si rezultat al acestei functii, imaginea devine mult mai clara si de dimensiuni mai mici. HLC HLC (Highlight Compensation) reduce intensitatea luminii orbitoare. Foarte efienta in recunoasterea numerelor de inmatriculare a masinilor pe timp de noapte. HCL-ul poate recunoaste orice spot de lumina si poate compensa acesta pentru a obtine o imagine clara. Back Light Compensation - BLC Functia BLC (Compensarea luminii din spate) este folosita adesea la imagini in care o sursa de lumina puternica se afla in spatele subiectului de interes. In acest caz, subiectul ar aparea doar ca un contur negru. BLC permite camerei sa regleze expunerea intregii imagini, pentru a evidentia corect subiectul in prim-plan. Defog Vremea afecteaza foate mult calitatea imaginii captate de camere de supraveghere de exterior. In functie de conditiile meteo, culoare si contrastul pot fi degradate in mod dramatic. Conditiile meteo nefavorabile ca poaie, ceata, praf pot afecta calitatea imaginii. Monitorizarea traficului si/sau a frontierei trebuie sa se efectueze sub orice fel de vreme. Reprezinta un impediment major sa nu se poate recunoaste daca un obiect aflat in miscare este o persoana sau un animal sau sa nu se poate identifica un numar de inmatriculare. Camerele CCTV de exterior trebuie sa aibe capacitatea de a elimina efectele meteorologice nedorite – ceata – dintr-un video, pentru a imbunatati calitatea imaginilor. tabilizator Electronic de Imagine – EIS Este o functie a camerei de imbunatatire a imaginii, folosind procesarea electronica. EIS minimizeaza tremuratul dispozitivului provocat de vibratii sau conditii exterioare. Astfel, rezulta imagini mai clare care pot fi utilizate fara a fi nevoie de prelucrare digitala. 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. IP66 Nivelul de protectie asigurat de carcasa camerei impotriva accesului la componentele interne, a corpurilor solide sau a patrunderii apei. IP 66 indica un grad superior de protectie asupra factorilor externi 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 -30°C si +60°C si cu umiditate de pana la 95% Camera Image Sensor 1/2.8" Progressive Scan CMOS Max.
