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

The Hikvision DS-2CD2047G3-LI2UY(2.8mm) is a white 4MP fixed mini bullet network camera designed for high-detail IP CCTV surveillance in homes, businesses and professional security installations. This exact version combines a 4MP image sensor, a wide-angle 2.8mm F1.0 fixed lens, Hikvision ColorVu imaging, Smart Hybrid Light, built-in arrayed dual microphones and deep-learning human and vehicle classification in a durable IP67-rated metal housing.

Maximum video resolution is 2688 x 1520. The 2.8mm lens provides a broad 111.1° horizontal field of view, making the camera particularly suitable for entrances, driveways, gardens, shop fronts, offices, warehouses, yards, corridors and other locations where broad scene coverage is more important than a narrow long-distance view.

4MP ColorVu Imaging with HikAI-ISP

The DS-2CD2047G3-LI2UY uses a 1/1.8-inch Progressive Scan CMOS sensor together with an F1.0 super-aperture lens. Hikvision ColorVu technology is designed to make greater use of available light so that useful colour information can be retained in very low-light environments.

The officially specified minimum illumination is 0.0001 Lux at F1.0 with AGC enabled, while the camera can operate at 0 Lux when supplementary lighting is active. HikAI-ISP processing supports improved image quality and noise reduction in challenging lighting conditions.

Scene-adaptive 130 dB Wide Dynamic Range helps balance areas containing both bright and dark sections, such as entrances facing daylight, illuminated shop fronts, doorways and vehicle access points. Additional image functions include BLC, HLC, 3D DNR, distortion correction, defog, electronic image stabilisation and configurable privacy masks.

2.8mm Wide-Angle F1.0 Lens

This product is specifically the 2.8mm fixed-lens version of the Hikvision DS-2CD2047G3-LI2UY. It must not be confused with the separate 4mm variant.

• 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 lens. These are standardised planning references rather than guaranteed real-world identification distances, as practical results depend on camera positioning, lighting, mounting height, target movement and environmental conditions.

Smart Hybrid Light with IR and White Illumination

The Hikvision DS-2CD2047G3-LI2UY integrates both infrared and white supplementary lighting. Smart Hybrid Light provides configurable supplementary lighting modes so the camera can be adapted to different night-time surveillance requirements.

The maximum officially specified supplementary light range is up to 40m. The infrared illumination uses an 850nm wavelength. Combining infrared and white lighting provides greater flexibility than a conventional IR-only camera when configuring night surveillance and colour imaging requirements.

Human and Vehicle Classification

Deep-learning analytics allow the Hikvision DS-2CD2047G3-LI2UY to classify specified detection events involving people and vehicles. This can help reduce irrelevant event notifications when the camera and detection areas are configured correctly.

Supported intelligent functions 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, scene change detection, motion detection, video tampering alarms and system exception events.

Analytics must be configured correctly for each installation. Detection performance can vary according to camera position, target size, lighting, environment and configuration.

Built-In Dual Microphones for Audio Recording

The DS-2CD2047G3-LI2UY includes a built-in arrayed dual-microphone for capturing audio alongside surveillance video when audio recording is enabled on a compatible CCTV system.

This base DS-2CD2047G3-LI2UY model should not be confused with Hikvision's separate /SL or /SRB variants that provide additional active warning functions. A built-in speaker, siren and active strobe are therefore not advertised as features of this exact product.

Local microSD and Network Storage

The camera contains an onboard memory-card slot supporting microSD, microSDHC and microSDXC cards with a maximum officially stated capacity of 512GB. This allows supported local recording configurations without relying exclusively on an external recorder.

The camera also supports NAS network storage using NFS or SMB/CIFS and Auto Network Replenishment functionality. A compatible Hikvision NVR can be used where centralised multi-camera recording, playback and CCTV system management are required.

A memory card is not stated as included with the standard camera package. A suitable compatible microSD card should therefore be selected separately when local recording is required unless the supplied package specifically states otherwise.

H.265+ Video Compression and Network Connectivity

The main video stream supports H.265, H.264, H.265+ and H.264+ compression. In 50Hz operation, the camera supports up to 25fps at its maximum 2688 x 1520 resolution.

Network connectivity is provided through a 10/100Mbps self-adaptive RJ45 Ethernet interface. Integration support includes ONVIF Profile S, Profile G and Profile T together with Hikvision ISAPI, SDK and ISUP. Compatible Hikvision client platforms include Hik-Connect, iVMS-4200 and HikCentral.

PoE or 12V DC Power

The Hikvision DS-2CD2047G3-LI2UY can be powered by either 12V DC or Power over Ethernet. PoE support follows IEEE 802.3af Class 3, allowing power and network data to use the same Ethernet cable when connected to compatible PoE equipment.

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

IP67 Outdoor Metal Construction

The camera uses a metal front cover, metal body and metal mounting bracket. Its IP67 ingress-protection rating makes it suitable for properly installed outdoor CCTV applications where protection against dust and weather exposure is required.

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

Where Can This Hikvision Camera Be Used?

The wide 2.8mm field of view makes this model particularly useful where a single camera needs to cover a broad scene. Typical applications include residential driveways and gardens, building entrances, retail premises, offices, warehouses, workshops, commercial yards, loading areas and general perimeter CCTV.

Camera quantity, mounting position, recording capacity, network bandwidth and lens selection should always be planned around the individual site rather than assuming one camera configuration is suitable for every property.
