Camera de supraveghere Hikvision DarkFighter IP Speed Dome 4MP DS-2DF8C425MHS-DEL, zoom motorizat

Descriere

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.

Zoom motorizat

Avantajele includ posibilitatea de zoom direct pe camera, imagini mai clare, contrast mai bun chiar si in conditii de iluminare scazuta sau la distante focale lungi. Avand si functia de autofocus nu mai este nevoie de o ajustare manuala la fiecare schimbare de cadru.

Pan Tilt Zoom – PTZ

Caracteristica unei camera de a se misca automat in mai multe directii oferind si posibilitatea de zoom automat.

-          Rotire in plan orizontal (Pan);

-          Inclinare in plan vertical (Tilt);

-          Aproprierea imaginii (Zoom) pentru observarea detaliilor aflate la distante mari.

Directia de miscare a camerei, poate fi controla de la distanta prin intermediul unui joystick , browser de internet sau aplicatia software. Acopera zone mari de supraveghere si inregistreaza fara interventia directa a utilizatorului conform unui plan stabilit.

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.

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)

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.

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.

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.

Smart IR

Smart IR este o tehnologie incorporata in unele camera de securitate, care regleaza intensitatea  Led-ului infrarosu a camerei de supraveghere, pentru a compensa distanta  fata de un obiect, astfel incat infrarosul sa nu supraexpuna obiectul.

Stabilizator 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.

Privacy Masking

Privacy Masking este o caracteristica regasita la multe camere IP, folosita pentru a proteja intimitatea personala prin ascunderea unor parti a imaginii cu ajutorul unei zone disimulate.

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.

Face detection

Prin aplicarea tehnologiei de detectare a fetei, camerele IP, pot detecta precis trasaturile faciale umane, le pot analiza si declansa alarma in cazul in care este setata una.

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.

IP67

Nivelul de protectie asigurat de carcasa camerei impotriva accesului la componentele interne, a corpurilor solide sau a patrunderii apei. IP 67 indica un grad superior de protectie asupra factorilor externi si ofera protectie impotriva efectului de imersie, intre 15 cm si 1 m.

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 90%.
