Hikvision DS-2CD2T46G3-4IZY(2.8-4mm)/BLACK 4MP AcuSense Varifocal Bullet with 80m IR

Hikvision DS-2CD2T46G3-4IZY/BLACK — 4 MP AcuSense motorised varifocal bullet with 80 m IR

This is the black version of Hikvision's longest-range G3 AcuSense bullet. A motorised 2.8–4 mm lens set remotely from software after mounting, 80 m of infrared, 130 dB WDR and a gigabit Ethernet port. Only the finish differs from the white model.

Eighty metres of infrared — the longest in the range

This is the whole reason the 4IZY exists alongside the 2IZY. The two cameras are identical in sensor, lens, analytics, housing and dimensions. The only differences are the illuminator and the power that drives it:

• 2IZY — 60 m IR, 11.5 W on 802.3af
• 4IZY — 80 m IR, 12.5 W on 802.3af

An extra 20 m of usable night range for one watt, and still on a standard af port. For a long unlit driveway, a yard perimeter or an approach road, that is a straightforward decision — and £9 trade.

The illuminator outruns the optics here

Worth being straight about this, because it is unusual. DORI at 2.8 mm is detect 66.6 m, observe 26.4 m, recognise 13.3 m, identify 6.7 m; at 4 mm, detect 79.2 m, identify 7.9 m.

So the 80 m illuminator actually reaches slightly beyond the camera's detection range. Almost every other camera in this catalogue has the opposite problem — 30 m of IR against 89 m of optics. Here you are getting the full benefit of the lens after dark, with nothing left on the table.

Why specify black

At 287 mm and 1,165 g this is a full-size bullet, so the finish does real work. Against dark brickwork, exposed steelwork, a black fascia or a slate soffit it recedes where a white body of this size would dominate an elevation. Where the camera is meant to be seen as a deterrent, white does that better.

Gigabit Ethernet

A 10/100/1000 port, where almost everything else in this catalogue — including the 4K and 12 MP models — is 10/100. At an 8 Mbps stream that changes nothing for one camera, but it matters on gigabit switching infrastructure.

Read the lens range carefully

The zoom is 2.8 to 4 mm — short, not the 2.8–12 mm of the larger varifocals. The gain across the whole range is about a metre of identification distance. It exists so an installer can fine-tune framing from a laptop rather than returning to site. Specify it for mounting flexibility; the reach here comes from the illuminator, not the zoom.

No audio at all

This model has no microphone, no speaker and no audio or alarm terminal block — Ethernet, microSD and reset key are the only interfaces. For audio or an on-camera siren, the DS-2CD2T46G3-IZS2UY/SL adds both, though that model carries only 60 m of IR.

130 dB WDR, and an honest note on low light

Dynamic range is 130 dB, above the 120 dB of the G2H range. But the aperture is F1.6 on a 1/3" sensor, so minimum illumination is 0.001 lux — the same as the G2H turrets. Its night advantage is entirely the 80 m illuminator.

Imaging

• 1/3" progressive scan CMOS, 2688 × 1520 at 25 fps (50 Hz)
• F1.6 aperture, 0.001 lux in colour, 0 lux with IR on
• 130 dB WDR, SNR ≥ 52 dB
• 80 m Smart Supplement Light IR at 850 nm
• Motorised 2.8–4 mm lens on a Ø14 mount, depth of field from 1.1 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 8 Mbps
• microSD/SDHC/SDXC to 512 GB with encryption and health detection, plus NAS (NFS, SMB/CIFS) and ANR
• 1 RJ45 10/100/1000 Mbps gigabit Ethernet port
• ONVIF Profile S, T and G; ISAPI, SDK and ISUP
• iVMS-4200, Hik-Connect and HikCentral
• AcuSense human and vehicle classification plus face capture

Power, build and environment

• PoE IEEE 802.3af Class 3, max. 12.5 W, or 12 VDC 0.91 A max. 11 W — no 802.3at switch needed despite the 80 m illuminator
• Metal front cover, body and bracket in black; IP67 to IEC 60529-2013
• −30 °C to 60 °C, humidity 95% or less non-condensing
• 88.7 mm × 91.2 mm × 287.2 mm, approx. 1,165 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
• A microSD card for edge recording or ANR backfill — not supplied
• A matching black pole or corner bracket if it is not mounting flat to a wall

Frequently asked questions

Is the black version any different to the white one?

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

Is it worth the step up from the 2IZY?

If the view is long and unlit, yes — 80 m of infrared against 60 m, for one extra watt and about £9 trade. Everything else about the two cameras is the same.

Does it record sound?

No. This model has no audio hardware at all.

Will it run on an 802.3af switch?

Yes — 12.5 W on Class 3, despite the 80 m illuminator.
