Hikvision DS-2CD23126G3-I2UY(2.8mm)/BLACK 12MP AcuSense Turret

Hikvision DS-2CD23126G3-I2UY/BLACK — 12 MP AcuSense turret in black

This is the black version of Hikvision's 12 MP G3 turret. Electronically it is identical to the white model: a 1/1.8" sensor at 4608 × 2592, AcuSense classification, arrayed dual microphones and 130 dB WDR, in the same compact all-metal housing as the 4 MP and 8 MP models. 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.

What twelve megapixels actually buys you

Detail at distance. At 2.8 mm the DORI figures are detect 117 m, observe 46 m, recognise 23 m, identify 11 m — against 89 m and 8 m on the 8 MP G2H turret in the same body. Identification reaches roughly 40% further from the same mounting position, across a slightly narrower 94.2° field.

It also lets you crop into recorded footage and still have something usable, which is the practical reason most people specify 12 MP: one camera covering a forecourt can be digitally zoomed after the fact rather than needing a second camera aimed at the door.

Two trade-offs worth understanding before you specify it

• The aperture is F1.6, not F1.0. Every G2H model in this catalogue uses an F1.0 lens. F1.6 admits roughly a third as much light. Hikvision still quote 0.0008 lux because the sensor is large and DarkFighter processing compensates, but this is not the camera to choose purely for low light — the 8 MP DS-2CD2386G2H-IU at F1.0 is the better dark-scene performer.
• Full resolution runs at 20 fps, not 25. To get 25 fps you drop to 3840 × 2160. For most surveillance that is irrelevant; for anything involving fast movement close to the lens it is worth knowing.

There is also a real storage cost: the bit rate ceiling is 24 Mbps against 16 Mbps on the 8 MP models, so budget around 50% more disk per camera.

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 it, and on a design-led frontage the finish can decide whether a scheme is approved. Where the camera is meant to be seen as a deterrent, white does that job better.

Ten and a half watts

Despite the resolution it runs on 802.3af Class 3, max. 10.5 W — no need for an 802.3at switch. That keeps it usable on existing infrastructure and on recorders with a tight total PoE budget.

Imaging

• 1/1.8" progressive scan CMOS, 4608 × 2592 at 20 fps (25 fps at 3840 × 2160)
• F1.6 aperture, 0.0008 lux in colour, 0 lux with IR on
• 130 dB WDR — the wider of the two ratings Hikvision use in this range
• 30 m Smart Supplement Light IR at 850 nm
• 2.8 mm fixed lens on an M16 mount, depth of field from 2.9 m
• BLC, HLC, 3D DNR, distortion correction and Defog; 4 programmable polygon privacy masks

Audio, storage and network

• Arrayed dual built-in microphones. No speaker, and no alarm or audio terminal block — Ethernet, microSD and reset key are the only physical interfaces.
• H.265+/H.265/H.264+/H.264, 32 Kbps to 24 Mbps
• microSD/SDHC/SDXC to 512 GB, plus NAS (NFS, SMB/CIFS) and ANR
• ONVIF Profile S/T/G, ISAPI, SDK and ISUP; iVMS-4200, Hik-Connect and HikCentral
• The Ethernet port is 10/100, not gigabit. At a 24 Mbps ceiling that is still inside the port's capacity, but it is the tightest margin of any camera in this range.

Build and environment

• Metal cover and metal main body in black; IP67 and NEMA 4X anti-corrosion
• −30 °C to 60 °C, humidity 95% or less non-condensing
• Ø138.3 mm × 115.4 mm, approx. 750 g

What you'll need with it

• An 802.3af (or better) PoE switch or NVR port, or a 12 VDC supply
• A recorder that supports 12 MP on the channel count you need — not all do
• An AcuSense-capable Hikvision NVR to carry human/vehicle classification through to smart search
• A microSD card for edge recording or ANR backfill — not supplied
• Storage sized for up to 24 Mbps per camera
• A matching black bracket if it is not going straight onto a flat soffit

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.

Will my recorder handle 12 MP?

Check before ordering. Many NVRs cap per-channel resolution at 8 MP, and the 24 Mbps stream needs headroom in the recorder's total bandwidth budget.

Is it better in the dark than the 8 MP models?

Not necessarily. Its lens is F1.6 where the G2H models are F1.0. Choose 12 MP for detail and cropping, not for low light.

Does it record sound?

Yes — arrayed dual microphones. Check that recording audio is lawful and signposted for your site before enabling it.
