Hikvision 8 MP AcuSense Bullet Camera, 2.8 mm, DarkFighter, Black DS-2CD2T86G2H-2I(2.8mm)/BLACK

Overview

This is an 8 MP Hikvision bullet camera, the long cylindrical style that shows clearly where it is pointing. The black housing suits dark walls, soffits and cladding.

The 2.8 mm lens gives a wide view, so it suits scenes where the whole area matters more than distant detail.

How it works

• DarkFighter: Hikvision's low-light technology, paired here with an F1.0 lens, keeps colour pictures down to 0.0008 Lux @ (F1.0, AGC ON).
• AcuSense: deep learning sorts people and vehicles from other movement, so other movement triggers fewer alerts.
• IR night vision: when it gets too dark, 850 nm infrared lights the scene in black and white up to 60 m.

What the figures mean in practice

• DORI: the distances at which you can detect (89 m), observe (35 m), recognise (17 m) and identify (8 m) a person with this lens.
• 120 dB WDR: helps where a bright sky or doorway sits behind a darker subject.
• H.265+: compression that cuts storage and bandwidth compared with plain H.264.

Installing it

One network cable carries power and video when the switch or recorder gives PoE IEEE 802.3af. The bracket adjusts in pan, tilt and rotate.

For a neat finish, the DS-1280ZJ-S(Black) junction box is the maker's matching accessory and hides the cable joints.

Planning your system

The camera needs a recorder or video software, storage and PoE power. A Hikvision NVR is the usual partner; a separate PoE switch suits jobs where the cameras are far from the recorder.

Standards and ratings explained

• IP67: dust tight and protected against temporary immersion in water, so it is built for outdoor mounting.
• No specific protection: Hikvision's lowest anti-corrosion level, meant for areas where no specific anti-corrosion protection is needed.
