The Hikvision DS-2CD2146G2-ISU is a 4MP AcuSense dome network camera designed for reliable security monitoring in homes and commercial premises. It features DarkFighter technology for excellent low-light performance and 120dB true WDR to maintain clear images in challenging lighting conditions. AcuSense deep learning technology distinguishes people and vehicles from other movement, helping reduce unwanted motion detection alerts. The built-in microphone provides audio monitoring, while infrared illumination provides night vision up to 30 metres. Choose from 2.8mm, 4mm or 6mm lens options to suit your installation.
