Hikvision DS-2CD2047G3-LI2UY 4MP 2.8mm Black ColorVu Bullet Camera

The Hikvision DS-2CD2047G3-LI2UY(2.8mm)(Black) is a 4MP fixed mini bullet network camera designed for professional IP CCTV surveillance where reliable image quality, strong low-light performance and practical smart detection are required. This exact version is the black 2.8mm model and combines a 4MP image sensor, a 2.8mm F1.0 fixed lens, ColorVu imaging, Smart Hybrid Light, built-in arrayed dual microphone, deep-learning human and vehicle classification, microSD edge storage and IP67 weather resistance.

The maximum video resolution is 2688 x 1520. The 2.8mm lens provides a wide 111.1° horizontal field of view, making this version particularly suitable for entrances, driveways, gardens, shop fronts, offices, warehouses, loading areas, side paths and general perimeter protection where broader scene coverage is preferred.

Exact Product Variant

This listing is for the Hikvision DS-2CD2047G3-LI2UY(2.8mm)(Black). It is the black colour version with the 2.8mm lens. It must not be confused with the white version, the separate 4mm version, or the /SL and /SRB variants.

4MP ColorVu Imaging for 24/7 Colour Detail

The camera uses a 1/1.8-inch Progressive Scan CMOS sensor with an F1.0 super-aperture lens. Hikvision ColorVu technology is designed to improve low-light image performance and help retain useful colour information in darker scenes where conventional cameras may rely more heavily on monochrome night imaging.

The officially stated minimum illumination is 0.0001 Lux at F1.0 with AGC enabled, and 0 Lux with supplementary lighting. Hikvision also specifies HikAI-ISP image processing to help deliver improved imaging performance and noise control in difficult lighting conditions.

To help handle scenes with strong contrast, the camera also supports 130 dB WDR. This is useful in locations such as doorways, glazed entrances, loading bays and shop fronts where very bright and dark areas may appear in the same scene.

2.8mm Wide-Angle Lens

This exact model uses a 2.8mm fixed lens with F1.0 aperture. It is the correct choice where wide coverage is more important than a narrower, longer-distance view.

• Horizontal field of view: 111.1°
• Vertical field of view: 57.6°
• Diagonal field of view: 138.5°
• Aperture: F1.0
• Depth of field: approximately 2.5m to infinity

For DORI planning, Hikvision states approximately 61m detection, 24m observation, 12m recognition and 6m identification for the 2.8mm version. These are planning references only and actual results depend on mounting height, positioning, lighting, target movement, compression settings and general site conditions.

Smart Hybrid Light with Infrared and White Light

The Hikvision DS-2CD2047G3-LI2UY integrates infrared and white supplementary lighting. This Smart Hybrid Light design gives installers and users more flexibility than a basic IR-only camera, allowing the surveillance approach to be adapted to the site and the desired night-time image result.

The maximum officially stated supplementary light range is up to 40m. The infrared wavelength is 850nm. This makes the camera suitable for outdoor surveillance areas where dependable night coverage is required.

Human and Vehicle Classification

Deep-learning analytics are included to help the camera distinguish specified human and vehicle events more effectively than simple motion-only detection. This can improve alert quality when the system is configured correctly for the scene.

Supported intelligent events include line crossing detection, intrusion detection, region entrance detection and region exiting detection with human and vehicle target classification. The camera also supports face capture, motion detection, video tampering alarms, scene change detection and system exception events.

As with any analytics-based CCTV setup, performance depends on suitable installation, correct scene setup, target size, light levels and configuration.

Built-In Dual Microphone

The DS-2CD2047G3-LI2UY includes a built-in arrayed dual microphone for audio capture alongside video recording. This is useful in installations where audio support is required as part of the surveillance setup, subject to compatible recorder, software and lawful use.

This base DS-2CD2047G3-LI2UY model should not be confused with Hikvision's separate /SL or /SRB variants. A built-in speaker, active siren, strobe and two-way audio are therefore not claimed in this listing because those features are associated with different variants.

Storage Options

The camera supports onboard microSD, microSDHC and microSDXC cards up to 512GB. This allows local edge recording where required. The camera also supports NAS storage using NFS or SMB/CIFS and can be used with a compatible Hikvision NVR where centralised recording and multi-camera management are needed.

A memory card is not stated as included with the standard camera package. If local storage is required, a compatible card should be selected separately unless your own supplied package explicitly includes one.

Video Compression and Network Compatibility

The main stream supports H.265, H.264, H.265+ and H.264+ compression. In 50Hz mode, the camera supports up to 25fps at the full 2688 x 1520 resolution. Network connectivity is provided through a 10/100Mbps self-adaptive RJ45 Ethernet port.

Supported integration and software platforms include ONVIF Profile S, Profile G and Profile T, along with Hikvision ISAPI, SDK and ISUP support. Hikvision lists Hik-Connect, iVMS-4200 and HikCentral as compatible client platforms.

Power Options

The camera can be powered by 12V DC or Power over Ethernet. PoE support follows IEEE 802.3af Class 3, allowing power and network data to be carried over one Ethernet cable when connected to compatible PoE equipment.

Hikvision specifies a maximum power consumption of 4.8W when using 12V DC and up to 6.5W when powered through PoE.

Outdoor Construction and Environmental Protection

The Hikvision DS-2CD2047G3-LI2UY uses a metal front cover, metal body and metal mounting bracket. The camera is rated IP67 for weather protection, making it suitable for properly installed outdoor CCTV applications.

Hikvision specifies an operating temperature range of -30°C to 60°C with humidity up to 95% non-condensing. The camera is also specified with NEMA 4X anti-corrosion protection.
