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.

   

  

  Senzorul infrarosu pasiv (PIR senzor) este un dispozitiv electronic care masoara radiatia infrarosie emisa de obiectele aflate in campul sau visual.Aparent miscarea este detectata atunci cand un corp cu o anumita temperature (cum ar fi om sau animal) trece prin fata sursei infrarosu (adica un alt corp, obiect) cu o alta temperature, cum ar fi un perete.

  Acest lucru  inseamna  ca senzorul detecteaza caldura  de la trecerea unui obiect  prin campul de actiune al senzorului si acel obiect rupe campul pe care senzorul l-a determinat anterior ca fiind “normal”.Orice obiect , chiar unul de aceiasi temperature ca si obiectele din jur va activa senzorul PIR daca corpul se deplaseaza  in campul visual al senzorului.

  Toate corpurile emit energie sub forma de radiatie.Radiatiile infrarosii sunt invizibile pentru ochiul uman, dar pot fi detectate de dispositive electronice concepute in acest sens.

  

  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.

  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.

  

  

  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.

  

  Auto White Balance - AWB

  Este o functie menita sa echilibreze culorile, astfel incat obiectele ce sunt de o culoare in realitate sa apara de aceeasi culoare si in imagine. Astfel incat albul si alte culori sa apara cat mai natural posibil. Foarte utila atunci cand camera este montata langa surse de lumina.

  

  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.

  

  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%.
