Product Overview

The Hikvision DS-2CD2T86G2-2I is a professional black 8MP AcuSense fixed bullet IP camera designed for high-resolution indoor and outdoor surveillance. This listing is specifically for the C-generation black model fitted with a 2.8mm fixed lens.

Its 1/1.8-inch progressive scan CMOS sensor records at up to 3840 × 2160 resolution, providing detailed 8MP video for monitoring entrances, commercial premises, driveways, warehouses, car parks, yards and building perimeters.

The camera combines Powered-by-DarkFighter low-light technology, up to 60 metres of infrared illumination, 120dB true Wide Dynamic Range and AcuSense human and vehicle classification. It can be powered using PoE or a suitable 12V DC supply and supports local microSD recording up to 256GB.

8MP 4K Video and DarkFighter Imaging

The DS-2CD2T86G2-2I records at a maximum resolution of 3840 × 2160, commonly described as 8MP or 4K UHD. This provides significantly more pixel detail than standard 1080p video and can assist when reviewing activity within the camera's field of view.

In 50Hz mode, normally used for UK installations, the main stream supports up to 25 frames per second at 3840 × 2160. The camera also supports lower resolutions and separate sub-stream and third-stream configurations for remote viewing and applications where reduced bandwidth is required.

Powered-by-DarkFighter technology improves image performance where ambient lighting is limited. Hikvision specifies a minimum colour illumination of 0.003 lux at F1.6 with automatic gain control enabled.

When the available light becomes insufficient, the camera switches to infrared-assisted black-and-white monitoring. It should not be advertised as a ColorVu camera or as providing permanent full-colour images in complete darkness.

Wide 2.8mm Fixed Lens

This exact black version uses a fixed 2.8mm lens. Hikvision specifies an approximate horizontal field of view of 111°, vertical field of view of 59° and diagonal field of view of 131°.

The wide viewing angle makes the camera particularly suitable for areas where broad scene coverage is required, including entrances, driveways, shop fronts, warehouse approaches, gardens and general building perimeters.

The lens has an F1.6 aperture and an M12 fixed mount. It does not provide optical zoom, motorised zoom or remote focal-length adjustment.

The camera housing allows manual adjustment through 0° to 360° pan, 0° to 90° tilt and 0° to 360° rotation. These adjustments are for installation positioning and do not provide powered PTZ movement.

60m Infrared Night Vision

The black DS-2CD2T86G2-2I uses built-in 850nm infrared illumination with a manufacturer-rated range of up to 60 metres.

Smart Supplement Light control helps regulate infrared output and can reduce excessive illumination when a person or object moves closer to the camera.

The actual usable night-viewing distance depends on factors including installation height, camera angle, surrounding surfaces, weather, ambient light and target reflectivity. The 60-metre figure describes the manufacturer's rated infrared illumination range rather than a guaranteed identification distance.

For the 2.8mm lens, Hikvision lists approximate DORI planning distances of 89.2 metres for detection, 35.4 metres for observation, 17.8 metres for recognition and 8.9 metres for identification.

DORI figures are theoretical planning guidance based on pixel density and should not be treated as guaranteed facial, clothing or vehicle-registration identification distances in every real installation.

AcuSense Human and Vehicle Classification

Hikvision AcuSense uses deep-learning algorithms to classify selected targets as people or vehicles. This helps the surveillance system focus on events that are more likely to be important.

When correctly configured, classification can reduce unnecessary motion alerts caused by unrelated movement such as animals, vegetation, rain or changing lighting conditions.

Supported intelligent events include:

• Line crossing detection
• Intrusion detection
• Region entrance detection
• Region exiting detection
• Scene change detection

Human and vehicle classification is also supported for motion detection. Event linkage options include recording, image capture, notification to a surveillance centre, email notification and upload to supported storage destinations.

Face capture is supported. Face capture means the camera can detect and capture suitable images containing faces. It should not be described as standalone facial-recognition or identity-matching technology.

120dB WDR and Image Enhancement

The camera provides 120dB true Wide Dynamic Range to improve visibility where bright and dark areas appear within the same scene. This can be useful around doorways, vehicle entrances and locations affected by strong daylight or headlights.

Additional image-enhancement functions include Backlight Compensation, Highlight Compensation and 3D Digital Noise Reduction.

Image settings including brightness, contrast, saturation, sharpness, gain and white balance can be adjusted through compatible client software or the camera's supported web interface.

The camera also supports day, night, automatic and scheduled day/night switching.

Efficient H.265+ Recording and Storage

Hikvision H.265+ compression is designed to reduce storage and network-bandwidth requirements compared with older compression methods while maintaining suitable video quality.

The main video stream supports H.265, H.265+, H.264 and H.264+. A configurable video bit rate from 32Kbps to 16Mbps provides flexibility for different recording and network requirements.

The camera contains a built-in microSD, microSDHC and microSDXC card slot supporting compatible cards with capacities up to 256GB.

The camera does not contain 256GB of included internal storage. A suitable memory card must be purchased separately unless your sales package specifically includes one.

Compatible NAS storage is also supported. Automatic Network Replenishment can be used with suitable Hikvision recording equipment and storage configuration to help replenish available footage following certain temporary network interruptions.

Network Compatibility and PoE Installation

The camera provides one self-adaptive 10/100Mbps RJ45 Ethernet interface. It supports common network protocols together with Hikvision clients including Hik-Connect, iVMS-4200 and HikCentral.

Open Network Video Interface Profiles S, G and T are supported, together with ISAPI and the Hikvision SDK. This can assist integration with compatible third-party recording and video-management systems.

Third-party compatibility does not guarantee that every AcuSense, face-capture, storage or smart-event function will operate through every recorder. Compatibility should be checked against the exact recorder and firmware.

The black -2I model can be powered using IEEE 802.3af PoE Class 3 or a suitable 12V DC supply. Maximum rated power consumption is 7.5W when using 12V DC or 9W through PoE.

PoE allows network data and electrical power to travel through a single Ethernet cable when the camera is connected to a compatible PoE NVR, network switch or injector.

Outdoor Metal Construction

The camera uses a metal housing and carries an IP67 rating for resistance to dust and water when correctly installed and sealed.

The specified operating-temperature range is -30°C to 60°C with humidity of 95% or less under non-condensing conditions.

Hikvision states that this model has no specific professional anti-corrosion protection. It should therefore not be advertised as a specialist marine, coastal or chemical-environment camera.

The camera measures approximately 105mm in diameter and 290mm in length and weighs approximately 1.27kg.

Technical Specifications

Is This the Right Camera for Your Installation?

The black 2.8mm DS-2CD2T86G2-2I is a strong choice when you need high-resolution 8MP video, a wide viewing angle, AcuSense human and vehicle classification, strong low-light performance and infrared monitoring across larger areas.

The wide 111° field of view makes it particularly useful where broad coverage is more important than a narrow long-distance view.

Consider another camera if you require built-in audio, two-way talk, ColorVu full-colour illumination, motorised zoom, a varifocal lens, PTZ movement or specialist marine-grade anti-corrosion protection.

Before ordering, confirm recorder compatibility, required viewing distance, mounting position, PoE capacity, storage requirements and whether the 2.8mm wide-angle lens is suitable for the intended scene.
