Hikvision DS-2CD2386G2H-IU(2.8mm)/GREY 8MP AcuSense Turret

Hikvision DS-2CD2386G2H-IU/GREY — 8 MP (4K) AcuSense turret in grey

This is the grey version of Hikvision's 8 MP G2H turret. Electronically it is identical to the white and black models: a 1/1.8" sensor at 3840 × 2160, an F1.0 lens, AcuSense classification, a built-in microphone and 30 m of infrared, drawing only 8 W. Only the finish differs.

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.

Why grey, rather than white or black

Grey is the finish most people never think to ask for, and it is often the right one. White disappears against render, painted soffits and pale stonework. Black disappears against dark fascias and exposed steel. Grey suits everything in between — galvanised steelwork, concrete, grey uPVC fascia, aluminium cladding, slate-grey composite panels, and the light industrial units and car parks where most of this hardware actually ends up.

On a mixed elevation it is the least conspicuous choice: a white camera on grey cladding reads as an addition, a grey one reads as part of the building. Where the camera is meant to be seen as a deterrent, white remains the better pick.

Eight watts for a 4K camera

The specification that stands out has nothing to do with the colour. This camera draws a maximum of 8 W on 802.3af Class 3 — less than the 4 MP DS-2CD2346G2H-IU in the same range, which needs 9 W, and under half what the strobe-and-siren models require on 802.3at.

On a recorder with a fixed total PoE budget shared across every port, that means you can populate the whole machine with 4K rather than mixing resolutions to stay inside the budget.

Coverage and DORI

This SKU is the 2.8 mm version on an M16 mount: horizontal FOV 108.8°, vertical 56.4°, diagonal 134.3°, with depth of field from 3.3 m. Hikvision's published DORI figures are detect 89 m, observe 35 m, recognise 17 m, identify 8 m. A 4 mm version narrows the view to 93.3° and pushes identification to about 10 m.

Note the standoff: at 3.3 m minimum focus this is not a camera for mounting directly above a doorway at head height. And the infrared reaches 30 m against an 89 m detection range, so after dark the illuminator is the limit rather than the optics.

What it has, and what it doesn't

The -IU suffix means a built-in microphone — audio recorded alongside video with no extra hardware. There is no speaker, no strobe, and no alarm or audio terminal block. Ethernet port, microSD slot and reset key are its only physical interfaces.

• Want two-way audio and an on-camera siren? The DS-2CD2386G2H-IS2U/SL adds both, at the cost of needing an 802.3at port.
• Need to wire in a detector or sounder? This model has no alarm I/O.

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 entrances and forecourts shot into strong backlight
• 30 m Smart Supplement Light IR at 850 nm
• 2.8 mm fixed lens, depth of field from 3.3 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
• The Ethernet port is 10/100, not gigabit — comfortable at 16 Mbps, but worth knowing on a 4K camera

Build and environment

• Metal cover and metal main body, grey finish; IP67 to IEC 60529-2013
• −30 °C to 60 °C, humidity 95% or less non-condensing
• Ø138.3 mm × 115.4 mm, approx. 775 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 recorder that supports 8 MP on the channel count you need
• A microSD card for edge recording or ANR backfill — not supplied
• Storage sized for 4K at up to 16 Mbps per camera
• A matching grey bracket if it is not going straight onto a flat soffit

Frequently asked questions

Is the grey version any different to the white one?

Only the finish. Sensor, lens, analytics, ratings and power draw are identical.

Will 8 W really run a 4K camera?

Yes. Hikvision rate it at 802.3af Class 3, max. 8 W. The deterrence models need 802.3at because of their strobe and speaker, not because of the sensor.

Does it record sound?

Yes — the -IU has a built-in microphone. Check that recording audio is lawful and signposted for your site before enabling it.

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.
