Hikvision DS-2CD2T86G2H-2I(4mm) 8MP AcuSense Bullet with 60m IR

Hikvision DS-2CD2T86G2H-2I (4 mm) — 8 MP (4K) AcuSense bullet with 60 m IR

This is the 4 mm version of Hikvision's 8 MP G2H fixed bullet: a 1/1.8" sensor at 3840 × 2160, AcuSense human and vehicle classification, DarkFighter low-light performance and 60 m of infrared in a full metal IP67 housing. It is the recording camera of the family rather than the deterrence camera — no strobe, no speaker, no audio.

AcuSense deep-learning classification separates people and vehicles from foliage, rain, shadows and animals, so line crossing, intrusion, region entrance and region exiting trigger only on real targets. Face capture is supported.

4 mm or 2.8 mm — which to order

Same camera, different lens. At 4 mm the field of view is 90° horizontal and the DORI figures are detect 109 m, observe 43 m, recognise 21 m, identify 10 m. At 2.8 mm the view widens to 105.1° but the figures drop to 89 m detect and 8 m identify.

Choose 4 mm where the camera looks down a length — a driveway, a car park aisle, a service road — and detail at distance matters. Choose 2.8 mm for breadth close in. Note the 4 mm holds focus from 3.8 m rather than 3.3 m, so it is the weaker option for anything mounted close to its subject.

One honest limit on this variant: the optics now reach considerably further than the light does. The 4 mm lens detects to 109 m but the 2I's infrared stops at 60 m. In genuine darkness beyond that distance you need ambient or added lighting. If the whole point of the install is long-range night coverage, the DS-2CD2T86G2H-4I carries an 80 m illuminator and pairs far better with this lens.

It runs on 802.3af

Maximum 12.5 W over IEEE 802.3af Class 3. The strobe-and-siren IS2U/SL models in the same family need 802.3at, so this camera drops into existing af infrastructure without a switch upgrade — and without giving up any image quality, since both share the same 1/1.8" sensor and F1.0 lens.

What it does not have

The 2I carries no microphone, no speaker and no audio or alarm terminal block. Ethernet port, microSD slot and reset key are the only physical interfaces. For two-way audio, an on-camera siren, or wiring in a detector or sounder, look at the ISU, IS2U or IS2U/SL models.

Imaging

• 1/1.8" progressive scan CMOS, 3840 × 2160 at 25 fps (50 Hz)
• F1.0 aperture, 0.0008 lux in colour, 0 lux with IR on
• 120 dB WDR for gateways, loading bays and forecourts shot into strong backlight
• 60 m Smart Supplement Light IR at 850 nm
• 4 mm fixed lens on an M16 mount, depth of field from 3.8 m
• BLC, HLC and 3D DNR; 4 programmable polygon privacy masks

Recording, storage and network

• H.265+/H.265/H.264+/H.264, 32 Kbps to 16 Mbps
• microSD/SDHC/SDXC to 512 GB, plus NAS (NFS, SMB/CIFS) and ANR to backfill footage recorded during a network outage
• ONVIF Profile S/T/G, ISAPI, SDK and ISUP; iVMS-4200, Hik-Connect and HikCentral; up to 6 simultaneous live view channels
• The Ethernet port is 10/100, not gigabit. Comfortable at 16 Mbps, but worth knowing on a 4K camera at design stage.

Build and environment

• Metal front cover, metal body and metal bracket; IP67 to IEC 60529-2013
• −30 °C to 60 °C, humidity 95% or less non-condensing
• 286.7 mm × 93.3 mm × 91.2 mm, approx. 1,180 g

What you'll need with it

• An 802.3af (or better) PoE switch or NVR port, or a 12 VDC supply
• An AcuSense-capable Hikvision NVR to carry human/vehicle classification through to smart search on the recorder
• A microSD card for edge recording or ANR backfill — not supplied
• Storage sized for 4K: at 16 Mbps peak this camera consumes roughly twice the disk of the 4 MP version
• Supplementary lighting if the scene extends beyond 60 m at night

Frequently asked questions

Is the 4 mm better than the 2.8 mm?

Not better, different. It sees further with more detail over a narrower field. For close, wide coverage the 2.8 mm is the right choice.

Should I buy this or the 4I?

The 4I has 80 m infrared instead of 60 m. If the view is long and unlit, the 4I is the better match for a 4 mm lens.

Does this camera have a microphone?

No — the 2I has no audio hardware.

Will it work on a third-party NVR?

It supports ONVIF Profile S, T and G, so it will record on most ONVIF recorders. AcuSense classification is best supported on Hikvision recorders.
