DS-2DE4A225IWG-E, Hikvision, 4-inch, 2MP, 25X zoom, Speed Dome

• Beeldvorming van hoge kwaliteit met een resolutie van 2 MP, tot 60 fps
• Uitstekende prestaties bij weinig licht dankzij Powered-by-DarkFighter-technologie
• Helder beeld bij sterk tegenlicht dankzij 120 dB WDR-technologie
• Dankzij de pan- en tilt-functie kan de camera interessante zones bewaken
• Dankzij de 25× optische zoom kunnen onderwerpen in uitgestrekte gebieden van dichterbij worden bekeken
• Tot 50 m IR-bereik zorgt voor veiligheid 's nachts
• Water- en stofbestendig (IP66)
• Richt zich op de classificatie van menselijke en voertuigdoelen op basis van deep learning
