Tehnologia Wide Dynamic Range
Wide Dynamic Range ajuta camera de supraveghere video pentru a compensa problemele legate de expunerea la lumina. Poate functiona pe zonele intunecate si luminoase ale imaginii si poate crea un echilibru pentru a imbunatati calitatea generala a imaginii.
Tehnologia Automatic Gain Control
Controlul automat al castigului (AGC) regleaza automat amplificarea electronica a semnalului video pentru a compensa nivelurile variate de iluminare a scenei.
Tehnologia Back Light Compensation
Este esentiala pentru captarea imaginilor clare in situatii de iluminare dificila. Adesea, aceasta este utilizata atunci cand o sursa de lumina puternica se afla in spatele subiectului de interes, facand ca subiectul sa apara doar ca un contur negru. BLC permite camerei sa ajusteze expunerea pentru intreaga imagine, asigurand astfel o expunere corecta a subiectului din prim-plan. Aceasta functie echilibreaza lumina, oferind detalii clare si precise, chiar si in conditii de iluminare contrastanta, permitand recunoasterea si identificarea corecta a subiectelor in orice situatie.
