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

The Hikvision DS-2CD2047G3-LI2UY/SL(2.8mm) is a white 4MP Smart Hybrid Light with ColorVu fixed mini bullet network camera designed for advanced residential, commercial and professional IP CCTV systems. This exact /SL variant combines high-resolution 4MP video, a wide-angle 2.8mm F1.0 lens, ColorVu low-light imaging, HikAI-ISP processing, Smart Hybrid Light, human and vehicle classification, built-in arrayed dual microphones, a built-in speaker, two-way audio and active white strobe and audible warning functions.

The maximum video resolution is 2688 x 1520. Its 2.8mm fixed lens provides a wide 111.1° horizontal field of view, making the camera particularly suitable for monitoring entrances, driveways, gardens, shop fronts, offices, warehouses, yards, loading areas and other locations where broad scene coverage is required.

Exact White 2.8mm /SL Variant

This product listing is specifically for the Hikvision DS-2CD2047G3-LI2UY/SL(2.8mm) in white. The lens, colour and /SL suffix are important because Hikvision also provides other versions within this camera family.

The /SL variant should not be confused with the standard DS-2CD2047G3-LI2UY or the separate /SRB version. The /SL model includes active warning functionality and uses a white flashing light. Hikvision specifies a red and blue flashing light for the separate /SRB model.

4MP ColorVu Imaging with HikAI-ISP

The Hikvision DS-2CD2047G3-LI2UY/SL uses a 1/1.8-inch Progressive Scan CMOS image sensor and an F1.0 super-aperture lens. Maximum resolution is 2688 x 1520, providing 4MP image detail for security monitoring, recorded evidence and digital playback.

Hikvision ColorVu technology is designed to provide useful colour imaging in extremely low-light environments. The officially stated minimum illumination is 0.0001 Lux at F1.0 with AGC enabled and 0 Lux when supplementary lighting is operating.

HikAI-ISP image processing helps improve image quality and noise reduction in challenging conditions. The camera also supports 130 dB Wide Dynamic Range, helping balance very bright and dark sections within the same image, such as doorways, glazed entrances, vehicle gates and illuminated shop fronts.

Additional image functions include BLC, HLC, 3D Digital Noise Reduction, distortion correction, defog, Electronic Image Stabilisation and four programmable polygon privacy masks.

2.8mm F1.0 Wide-Angle Lens

This exact version has a fixed 2.8mm lens with an F1.0 aperture. Its wide field of view makes it well suited to situations where broad coverage is more important than a narrow long-distance view.

• Lens: 2.8mm fixed
• Aperture: F1.0
• Horizontal field of view: 111.1°
• Vertical field of view: 57.6°
• Diagonal field of view: 138.5°
• Depth of field: approximately 2.5m to infinity

For DORI planning, Hikvision specifies approximately 61m detection, 24m observation, 12m recognition and 6m identification for the 2.8mm lens. These distances are standardised planning references rather than guarantees of identification performance in every installation. Lighting, mounting height, camera angle, movement and environmental conditions can affect practical results.

Smart Hybrid Light with Up to 40m Illumination

The Hikvision DS-2CD2047G3-LI2UY/SL combines infrared and white supplementary lighting through Smart Hybrid Light technology. Three supplementary lighting modes provide greater flexibility when configuring the camera for different night-time security requirements.

The maximum officially specified supplementary light range is up to 40m, with 850nm infrared illumination. This combination allows the system to make use of infrared monitoring, visible white illumination or intelligent lighting behaviour according to the selected configuration.

Human and Vehicle Classification

Deep-learning analytics allow the DS-2CD2047G3-LI2UY/SL to focus supported security events on people and vehicles. When correctly configured, this can make event detection more useful by reducing alerts caused by less relevant movement within the scene.

Supported perimeter functions include line crossing detection, intrusion detection, region entrance detection and region exiting detection with alarm triggering by specified human and vehicle target types.

The camera also supports face capture, motion detection with human and vehicle target filtering, video tampering alarms, scene change detection and system exception events.

Intelligent detection performance depends on correct positioning and configuration. Camera angle, target size, lighting, obstructions and environmental conditions should all be considered during installation.

Built-In Dual Microphones and Two-Way Audio

The Hikvision DS-2CD2047G3-LI2UY/SL includes an arrayed dual-microphone for real-time audio capture. Hikvision also specifies a built-in speaker on this /SL model, enabling supported two-way audio communication through a compatible Hikvision system.

The built-in speaker has a maximum stated power consumption of 2W and an officially specified maximum sound pressure level of 110 dB measured at 10cm.

This means the /SL version provides functionality that is not present on the standard base DS-2CD2047G3-LI2UY model. The exact /SL suffix should therefore remain consistent in the EKM product name, description, MPN, Merchant Center information and structured product data.

Active White Strobe and Audible Warning

The /SL variant supports active deterrence through audible warning and strobe light flashing. Hikvision specifically identifies the /SL version as using a white flashing light, while the separate /SRB model uses red and blue flashing lights.

Supported event linkage can include audible warning and strobe light flashing alongside recording, image capture, surveillance-centre notification and supported storage actions.

The availability and behaviour of active warning functions depend on system configuration and selected event rules. They should be configured appropriately for the installation environment.

Local Storage up to 512GB

The camera contains an onboard memory-card slot supporting microSD, microSDHC and microSDXC cards with an officially specified maximum capacity of 512GB. This provides an edge-storage option for supported recording configurations.

Network storage support includes NAS using NFS or SMB/CIFS together with Auto Network Replenishment. A compatible Hikvision NVR can also be used for centralised recording, playback, event management and multi-camera CCTV installations.

A memory card is not confirmed as included with the standard camera package. If local storage is required, a suitable compatible card should therefore be purchased separately unless the supplied package specifically states otherwise.

H.265+ Compression and Network Integration

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

A third video stream is supported under certain settings. Network connectivity is provided through a 10/100Mbps self-adaptive RJ45 Ethernet interface.

The camera supports ONVIF Profile S, Profile G and Profile T together with Hikvision ISAPI, SDK and ISUP integration. Compatible Hikvision client platforms include Hik-Connect, iVMS-4200 and HikCentral.

12V DC or IEEE 802.3at PoE

The DS-2CD2047G3-LI2UY/SL can be powered using 12V DC or Power over Ethernet. Because this /SL version contains additional speaker and active-warning hardware, its power requirements differ from the standard base model.

Hikvision specifies 12V DC ±25%, 1A with maximum power consumption of 12W. PoE follows IEEE 802.3at Class 4 with maximum stated PoE power consumption of 16W.

Installers should therefore ensure the PoE switch, injector or recorder PoE ports being used are suitable for the camera's specified IEEE 802.3at power requirement.

IP67 Outdoor Metal Construction

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

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

Hikvision DS-2CD2047G3-LI2UY/SL(2.8mm) Product Facts

Where Can This Camera Be Used?

The wide 2.8mm lens and active warning features make the DS-2CD2047G3-LI2UY/SL particularly useful for residential driveways, entrances, retail premises, warehouses, offices, yards, loading areas, workshops and other locations where wide surveillance coverage together with visible and audible deterrence may be beneficial.

Camera quantity, mounting position, network bandwidth, storage capacity and event configuration should always be planned around the actual site rather than assuming a single configuration will suit every installation.
