Description
DS-2CD2146G2H-I 2.8MM
Datasheet: DS-2CD2146G2H-ISU
Leveraging advanced deep learning algorithms, Hikvision’s AcuSense technology introduces classification alarms for human and vehicle targets to both front- and back-end devices. This system specifically emphasises the identification of human and vehicle targets, significantly enhancing the efficiency and effectiveness of alarms.
High quality imaging with 4 MP resolution
Excellent low-light performance with powered-by-DarkFighter technology
Clear imaging against strong backlight due to 120 dB true WDR technology
Efficient H.265+ compression technology
Focus on human and vehicle targets classification based on deep learning
Built-in microphone for real-time auto security(-SU)
Water and dust resistant (IP67) and vandal-resistant (IK10)
