Hikvision DS-2CD2087G3-LI2UY | 8MP Smart Hybrid Light ColorVu Bullet | 2.8mm Lens, Mic & Anti-Corrosion

FAQs

What makes the 2.8mm lens ideal for certain applications?

The 2.8mm lens provides a wide 108.8° horizontal field of view, making it perfect for monitoring broad areas where comprehensive coverage is the priority. This wide angle is particularly suited to car parks, building entrances, reception areas, loading bays, and yards where you need to see the entire scene rather than focus on distant detail. The wider coverage means fewer cameras are needed to monitor large open spaces, reducing overall system costs whilst maintaining complete situational awareness.

How does the arrayed dual-microphone system improve audio performance?

The arrayed dual-microphone configuration in the 2U model provides significantly better audio quality than single microphone designs. The dual array enables environmental noise filtering, which actively reduces background sounds like wind, traffic, or machinery whilst preserving speech and relevant audio events. This spatial arrangement also improves audio directionality and clarity, making the camera more effective for applications requiring audio verification, two-way communication, or audio-triggered alerts in noisy environments.

What is ColorVu 3.0 and how does it differ from earlier versions?

ColorVu 3.0 represents Hikvision’s latest advancement in low-light colour imaging technology. Beyond the F1.0 aperture and high-sensitivity sensor of previous versions, ColorVu 3.0 adds HikAI-ISP (Image Signal Processing) for superior noise reduction and dynamic motion trail reduction. It also incorporates 3D LUT technology for accurate colour correction and matching, plus AI-powered WDR that intelligently determines when to activate Wide Dynamic Range based on environmental brightness. The result is cleaner, more natural-looking colour footage in challenging lighting conditions.

How does Smart Hybrid Light decide when to use IR versus white light?

Smart Hybrid Light offers three operating modes to suit different security requirements. In IR-only mode, the camera uses 850nm infrared illumination for covert black and white surveillance. In white light mode, it provides continuous colour illumination for deterrence and colour recording. The smart mode automatically switches between IR and white light based on detected events – for example, switching to white light when a person or vehicle is detected, providing both visual deterrence and colour footage for identification whilst remaining in subtle IR mode the rest of the time.

What are DORI distances and why do they matter?

DORI stands for Detection, Observation, Recognition, and Identification – industry-standard measurements of a camera’s effective range for different tasks. For the 2.8mm model: Detection (89m) means you can detect that something is present; Observation (35m) lets you determine basic characteristics like clothing colour; Recognition (17m) allows you to recognize a previously seen person; Identification (8m) enables definitive identification. These distances help specifiers choose the right lens for their specific security objectives – the 2.8mm excels at wide-area detection and observation rather than long-range identification.

Is the camera suitable for coastal or corrosive environments?

Yes, the DS-2CD2087G3-LI2UY carries NEMA4X anti-corrosion certification, classifying it at Hikvision’s “moderate protection” level. This makes it suitable for coastal areas approximately 2 kilometres from coastlines, regions affected by acid rain, and light industrial environments. The all-metal housing has special treatment to resist oxidation and chemical degradation. However, for installations directly on coastlines, docks, or in heavy chemical/industrial facilities, Hikvision recommends their top-level protection models specifically engineered for extreme corrosive conditions.

Can this camera work with non-Hikvision recording systems?

Absolutely. The camera is ONVIF Profile S, G, and T compliant, ensuring compatibility with third-party video management systems and network video recorders that support these standards. It also supports standard protocols like RTSP for video streaming. Additionally, the camera has built-in edge recording to microSD card (up to 512GB), providing backup recording capability independent of any network recorder. This flexibility makes it suitable for both Hikvision-native systems and mixed-manufacturer installations.

What’s the difference between the DS-2CD2087G3-LI2UY and DS-2CD2087G3-LIY models?

The key difference is indicated by the “2U” designation in the model number. The DS-2CD2087G3-LI2UY includes an arrayed dual-microphone system for audio monitoring with environmental noise filtering, whilst the DS-2CD2087G3-LIY model without “2U” has no built-in microphones. All other specifications – including ColorVu 3.0, Smart Hybrid Light, AcuSense AI, and video performance – remain identical between the models. Choose the 2U version if audio monitoring or two-way communication is required for your application.
