Hikvision DS-2CD2066G2H-IU 6MP AcuSense Mini Bullet Camera with Microphone

The Hikvision DS-2CD2066G2H-IU is a 6MP mini bullet with an F1.0 lens and an unusually wide field of view — 114.8 degrees at 2.8mm.

Six megapixels in a 74mm body

At 3200 × 1800 it carries half again the detail of a 4MP camera, on a larger 1/2.4" sensor — and it does it in the same compact housing as the 4MP models, drawing 8.5 watts on ordinary 802.3af PoE.

The F1.0 aperture holds colour down to 0.001 lux before the 40 metres of infrared takes over.

A genuinely wide view

114.8° horizontal at 2.8mm is wider than most cameras in this class, which typically manage 99–104°. On a driveway, a forecourt or a shop floor that is a meaningful amount of extra scene from the same mounting point — often the difference between one camera and two.

The 4mm option narrows to 94° with slightly more reach.

What it will actually show you

Note that the extra resolution buys coverage, not distance — identification is still under seven metres, because the wider lens spreads those pixels over a bigger scene. If you want identification further out, a narrower lens matters more than more megapixels.

AcuSense and a microphone

Deep-learning classification separates people and vehicles from weather, animals and headlights, with line crossing, intrusion, region entrance and exit, plus face capture. The U denotes a built-in microphone.

Recording audio carries legal considerations — see our FAQ on CCTV law.

Worth knowing before you order

The lens is fixed — 2.8mm or 4mm. Choose before ordering.

6MP uses more storage than 4MP at the same settings. Size it with our storage calculator.

No speaker, no alarm terminals. A microphone for listening only. For two-way audio see the G3 audio bullet.

Frequently asked questions

Is 6MP worth it over 4MP here?

For coverage, yes — more detail across a wider scene. For identification distance, no: both identify under seven metres, because the wide lens spreads the pixels. Choose 6MP for a big scene, a longer lens for distance.

How wide is 114.8 degrees in practice?

Wider than most cameras in this class, which typically manage around 100°. It often covers a forecourt or shop floor that would otherwise need two cameras.

How much PoE does it need?

8.5W on standard 802.3af — it runs on almost any switch or NVR.

Does it have audio?

A built-in microphone, yes. No speaker, so it listens but does not talk back.
