§ 01Overview

What the DS-2CD2186G2H-ISU is

The Hikvision DS-2CD2186G2H-ISU is a full-size 8 MP AcuSense dome for sites that need dependable 4K coverage in changing light.

It captures 3840 x 2160 detail, and Powered-by-DarkFighter technology lifts low-light performance so dusk and night scenes stay usable.

AcuSense deep-learning analytics classify human and vehicle targets, keeping motion alarms and perimeter rules - line crossing, intrusion, region entrance and exit - focused on people and cars.

It has a built-in microphone for recording audio, 130 dB true WDR to hold detail against bright backlight, and 30 m infrared for night coverage.

The dome housing is IP67 against dust and rain and IK10 against impact, which is a step up in vandal resistance over a mini dome and makes it well suited to car parks, schools, hospitals and building entrances.

Two honest notes: it has a built-in microphone for audio recording but no built-in speaker, so it is not a two-way talk camera on its own - add an external speaker to the audio output if you need that.

And night images are black-and-white from the infrared.

Power it from PoE or 12 VDC and record it to a Hikvision AcuSense NVR for the best results.

§ 04Why choose this

Built for the way you actually use the DS-2CD2186G2H-ISU

Reliable 4K day and night

8 MP detail with Powered-by-DarkFighter low-light keeps dusk and night scenes usable.

Alerts that matter

AcuSense human and vehicle classification keeps motion and perimeter alarms on people and cars.

Built to take a hit

An IP67, IK10 dome stands up to weather and tampering in car parks and public areas.

Audio context

A built-in microphone records sound alongside the video for fuller evidence.

§ 05Where it fits

Right at home in these scenarios

Car parks and forecourts

Cover vehicle areas with 4K detail and AcuSense vehicle alerts in an IK10 housing.

Schools and campuses

Watch entrances and grounds with a tough, vandal-resistant dome.

Corporate entrances

Monitor lobbies and approaches with reliable low-light 4K and audio.

Hospitals and public buildings

Keep dependable coverage where cameras need impact resistance.

§ 06Setup

Installation & setup

01

What's in the box

One DS-2CD2186G2H-ISU 8MP dome camera with mounting template and fixings. Power supply, network cable and any NVR are supplied separately.

02

Installation requirements

Mount it on a wall, eave or ceiling over the area to cover and power it from a PoE switch or NVR or a 12 VDC supply. Connect the network, set the day/night and AcuSense perimeter rules in the software, and add it to a Hikvision NVR for recording and event search. Connect an external speaker to the audio output if you need talk-back.

§ 07Questions

Frequently asked about the DS-2CD2186G2H-ISU

Q.01

Does the DS-2CD2186G2H-ISU have two-way audio?

It has a built-in microphone to record audio with the video, but it does not include a built-in speaker, so it is not a two-way talk camera by itself. You can connect an external speaker to the audio output if you need to talk back through it.

Q.02

What is Powered-by-DarkFighter and how is it different from ColorVu?

Powered-by-DarkFighter is Hikvision's sensitive low-light sensor technology that produces clean images in very low light. It is not the same as ColorVu, which keeps full colour at night using white light - this camera uses infrared at night, so its dark-scene images are black-and-white.

Q.03

How does AcuSense reduce false alarms?

AcuSense uses deep learning to classify human and vehicle targets, so motion alarms and perimeter rules such as line crossing and intrusion trigger on people and cars and ignore animals, rain and moving foliage.

Q.04

How tough is it compared with a mini dome?

It is rated IP67 against dust and rain and IK10 against impact. The IK10 vandal rating is higher than a typical mini dome's IK08, so it suits car parks, schools and public entrances where cameras can be tampered with.

Q.05

How far does the night vision reach?

It has 30 m of infrared night vision, giving clear black-and-white coverage in complete darkness up to that distance.

Q.06

How is it powered?

It runs on standard PoE or a 12 VDC supply, so you can power and network it over a single cable from a PoE NVR or switch, or use a local 12 VDC source.

Q.07

Which recorder should I pair it with?

Use a Hikvision AcuSense-compatible NVR so the human and vehicle event data is kept for faster searching. An 8-channel PoE NVR suits a small site; step up to 16 channels for larger jobs.

§ 09Bundles

Recommended packages

01

Record and search it

Connect it to a Hikvision DS-7608NI-M2/8P NVR for continuous recording and AcuSense human and vehicle search.

02

Pair with a mini dome

Mix in the compact DS-2CD2586G2-IS 8MP mini dome where a smaller camera suits the spot.

03

4K AcuSense recorder

The DS-7608NI-I2/8P NVR is an alternate 4K PoE NVR with AcuSense support.
