Camera de supraveghere rezistenta la explozii Speed Dome Hikvision DS-2DF4220-DX(S6/316L)

Descriere

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.

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.

Tehnologia EXIR

Ofera o iluminare mai eficienta, cu 30 % fata de led-urile IR traditionale. Pentru a putea profita din plin de lumina IR, aceasta, este produsa sub forma dreptunghiulara, pentru a se potrivi mai bine pe dimensiunea unui ecran de 4:3 sau 16:9. Imaginile vor fi iluminate uniform, fara zone supra-iluminate in centru si intunecate in lateral.

Functia PoC permite utilizarea unui singur cablu pentru transmiterea ambelor semnale necesare functionarii camerelor: alimentare si semnal video. Reduce considerabil pretul si timpul de lucru alocat instalarii

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, clara iar pixelii nedoriti  sunt eliminati 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.

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.

Tehnologia Smart IR este folosita pentru a rezolva problema contrastarii imaginii de catre LED-urile infrarosu, cum ar fi fetele oamenilor, cand acestia sunt prea aproape de ele pe timp de noapte.

IP 67

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 -40°C si +60°C si cu umiditate de pana la 90%
