DS-2CD2047G2-LU 4MP IP CAMERA BULLET

This is a Hikvision DS-2CD2047G2-LU 4MP ColorVu fixed-lens bullet network camera, supporting audio input and featuring "full-color imaging + intelligent detection." It's suitable for outdoor security scenarios such as residential areas, shops, and warehouses, and is a very common model in the Hikvision EasyIP 4.0 / ColorVu series.

Main Features:
This camera utilizes ColorVu technology, enabling full-color imaging even in extremely low light conditions (0.0005 lx).  It doesn't rely on traditional black-and-white infrared imaging at night, resulting in better detail and color reproduction.  Combined with 130 dB Wide Dynamic Range (WDR), it effectively handles backlit scenes, such as doorways and roller shutter entrances with high contrast.

It has a built-in microphone for capturing ambient sound, enabling simultaneous audio and video recording; some variants with the /SL suffix also support white light flashing and voice alerts for sound and light alarms and active defense (Live Guard).

Intelligent Analysis and Application Scenarios:
The DS-2CD2047G2-LU supports AcuSense deep learning algorithms, allowing for the classification and detection of "people and vehicles," reducing false alarms from tree shadows, animals, etc. It's suitable for integration with NVRs or platforms for rule-based alarms such as area intrusion, line crossing, and entering/leaving areas.

Typical applications include: residential perimeters, parking lot entrances/exits, shop entrances, construction sites, and small campuses – scenarios requiring 24-hour color monitoring, illumination over a certain distance, rain and dust protection, and a moderate budget.
