Hikvision DS-2CD2646G2H-IZS(2.8-12mm)/BLACK 4MP AcuSense Varifocal Bullet

Hikvision DS-2CD2646G2H-IZS/BLACK — 4 MP AcuSense motorised varifocal bullet

This is the black version of Hikvision's 4 MP G2H varifocal bullet. Electronically it is identical to the white model: a motorised 2.8–12 mm lens set remotely from the browser or client software after mounting, AcuSense classification, 60 m of infrared, and an IP67 / IK10 all-metal housing. 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.

The best-matched long-range camera in the G2H range

Most cameras in this family have optics that outrun their illuminator. This one is the exception, and it is the reason to choose it.

Zoomed wide it detects to 63.4 m and identifies at 6.3 m. Zoomed tele it observes to 71.7 m, recognises at 36.1 m and identifies at 18.1 m. Behind that sits 60 m of infrared — half as much again as the 40 m on the varifocal turrets in the same range. So the useful night distance actually approaches what the lens can resolve, rather than falling well short of it.

For a long driveway, a yard perimeter, a car park or an approach road that has no lighting of its own, that pairing is what matters.

Compared with the DS-2CD2H46G2H-IZSY turret

Same 4 MP sensor, same 2.8–12 mm motorised lens, same wide-end DORI. Three things separate them:

• IR: 60 m here, 40 m on the turret
• Power: this bullet needs 802.3at at up to 18 W; the turret runs on 802.3af at 12.95 W. Check your switch or NVR port budget — this is the difference that catches people out.
• Size: 333.8 mm and 1,490 g against a 143 mm, 1,270 g turret. This is a substantial piece of hardware and needs a solid mounting position.

Choose the bullet for reach and night performance, the turret for discretion and easier power.

Why specify black

Against dark brickwork, exposed steelwork, a black fascia or a slate soffit, a black bullet recedes where a white one of this size would dominate. Given the length of this camera, the finish does more work here than on the compact turrets. Where the camera is meant to be seen as a deterrent, white does that job better.

No microphone — check before you specify

This model has no built-in microphone. It has 1 audio input (line in) and 1 audio output (line out) on a two-core terminal block, so audio needs an external microphone wired in. It does carry a proper 1 alarm in / 1 alarm out rated 24 VDC/24 VAC at 1 A — far more capable than the 30 mA outputs on the G2H domes, and enough to drive a real load.

Imaging

• 1/3" progressive scan CMOS, 2688 × 1520 at 25 fps (50 Hz)
• F1.0 aperture, 0.001 lux in colour, 0 lux with IR on
• 120 dB WDR, SNR ≥ 52 dB
• 60 m Smart Supplement Light IR at 850 nm
• Motorised 2.8–12 mm lens, Ø14 mount, depth of field from 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, 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 — ample at an 8 Mbps ceiling

Power, build and environment

• PoE IEEE 802.3at Class 4, max. 18 W — not 802.3af
• Or 12 VDC ± 25%, 1.21 A, max. 14.5 W. The DC connection is a two-core terminal block, not a barrel jack.
• Metal front cover, metal body and metal bracket in black; IP67 and IK10
• −30 °C to 60 °C, humidity 95% or less non-condensing
• Ø140 mm × 333.8 mm, approx. 1,490 g

What you'll need with it

• An 802.3at PoE switch or NVR port, or a 12 VDC supply terminated to bare conductors
• 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
• An external microphone if audio is required
• 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, analytics, ratings and power draw are identical.

Is the zoom adjusted remotely?

Yes. The lens is motorised, so focal length and focus are set from the web interface or client software — no ladder needed once it is mounted.

Does it have a microphone?

No — line-in only, for an external microphone.

Will it run on an 802.3af switch?

No. It is specified for 802.3at Class 4 at up to 18 W.
