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

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

This is the black version of Hikvision's 8 MP G2H turret, with the 2.8 mm lens. Electronically it is identical to the white model — a 1/1.8" sensor at 3840 × 2160 behind an F1.0 lens, AcuSense human and vehicle 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 specify black

Against a dark soffit, a black shopfront fascia, exposed steelwork or a slate ceiling, a black turret effectively disappears where a white one draws the eye. Architects and shopfitters routinely specify black for this reason, and on a design-led or heritage frontage the finish can decide whether a scheme is approved at all.

The reverse is equally true: where the camera is meant to be seen as a deterrent, white does that job better. Black is for coverage without visual intrusion.

Eight watts for a 4K camera

The standout specification here 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°, 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.

Be realistic about night: the infrared reaches 30 m against an 89 m detection range, so after dark the illuminator is the limit rather than the optics. Where the view is long and unlit, the bullets in this range carry 60 m or 80 m IR.

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. For two-way audio and an on-camera siren, the DS-2CD2386G2H-IS2U/SL adds both, at the cost of needing an 802.3at port.

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 in black; 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
• A matching black bracket if it is not going straight onto a flat soffit — a white mount under a black camera defeats the point

Frequently asked questions

Is the black version any different to the white one?

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

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 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.

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.
