Description

Designed for users who require dependable, high-quality security monitoring, the Hikvision DS-2CD2047G3-LI2UY combines intelligent imaging, AI-powered detection, and durable outdoor construction in a compact mini bullet design. Deep learning technology focuses on people and vehicles to reduce false alarms, while ColorVu imaging and Smart Hybrid Light ensure exceptional visibility in low-light environments. With IP67 weather protection, built-in microphones, two-way communication, and support for onboard storage, this camera delivers a complete surveillance solution for demanding indoor and outdoor installations.

Features

Clear Imaging with ColorVu Technology
The advanced 4MP sensor captures images at a maximum resolution of 2688 x 1520, delivering sharp detail for identifying people, vehicles, and important events. ColorVu technology provides vibrant full-color images throughout the night, improving visibility compared to conventional infrared-only cameras.

HikAI-ISP image processing further enhances image quality by reducing noise and improving clarity, even in challenging lighting conditions.

Smart Hybrid Light for Flexible Night Surveillance
The integrated Smart Hybrid Light system combines infrared illumination with white LED lighting, allowing the camera to automatically adapt to different environments. Three supplemental lighting modes help optimize visibility while balancing image quality and energy efficiency.

Lighting capabilities include:

• White light illumination up to 40 metres
• Infrared illumination up to 40 metres
• Automatic Smart Hybrid Light operation
• Active white flashing warning light

AI Detection for More Accurate Alerts
Deep learning technology helps distinguish between people and vehicles, reducing unwanted notifications caused by animals, weather, or other movement. This allows security personnel and property owners to focus on genuine security events.

Additional intelligent capabilities include:

• Motion detection
• Face capture
• Person and vehicle classification
• One configurable Region of Interest (ROI)

Built-In Audio and Active Deterrence
The camera includes dual array microphones for clear audio recording and supports two-way audio, allowing communication directly through the camera. When suspicious activity is detected, the integrated strobe light and audible alarm can actively discourage intruders.
