6MP High-Resolution Imaging

The DS-2CD2166G2H-ISU captures video at up to 3200 × 1800 resolution, providing excellent image detail for professional CCTV surveillance.

The additional detail available from a 6MP image can assist when reviewing:

• People
• Clothing
• Vehicles
• Entrances
• Property Activity
• Objects
• Security Incidents
• Commercial Activity

The camera supports up to 25fps at 3200 × 1800 in 50Hz environments, providing smooth high-resolution surveillance footage.

Powered-by-DarkFighter Technology

The DS-2CD2166G2H-ISU incorporates Hikvision's Powered-by-DarkFighter technology, designed to deliver improved imaging in challenging low-light environments.

Combined with its F1.0 aperture, the camera can capture more available light than conventional cameras with smaller apertures.

Hikvision specifies minimum colour illumination down to approximately:

0.001 Lux @ F1.0, AGC ON

and:

0 Lux with IR

This makes the camera particularly suitable for locations where ambient lighting may be limited.

Hikvision AcuSense Human & Vehicle Classification

The DS-2CD2166G2H-ISU incorporates Hikvision AcuSense deep-learning technology to classify human and vehicle targets in supported events.

Rather than treating every movement as equally important, AcuSense can help the surveillance system focus on security events involving people and vehicles.

This can help reduce unnecessary event notifications triggered by movement such as:

• Leaves
• Animals
• Rain
• Shadows
• Changing Light
• Other Non-Target Movement

When combined with a compatible Hikvision NVR, this provides a more intelligent CCTV system for event monitoring and footage review.

120dB True WDR

The camera features 120dB True Wide Dynamic Range, helping maintain useful image detail when very bright and dark areas appear within the same scene.

This is particularly useful for:

• Building Entrances
• Glass Shopfronts
• Lobbies
• Garages
• Covered Entrances
• Loading Areas
• Reception Areas
• Areas Facing Bright Daylight

Smart IR Night Vision – Up to 30m

When ambient light becomes insufficient, the camera can switch to infrared night surveillance.

The DS-2CD2166G2H-ISU provides Smart IR supplementary illumination up to 30 metres, allowing the camera to continue monitoring in darkness.

The infrared wavelength is 850nm, with Smart Supplement Light technology helping manage illumination according to the monitored scene.

Built-In Microphone

The DS-2CD2166G2H-ISU includes a built-in microphone for real-time audio security.

Audio recording can provide valuable additional context when reviewing incidents around:

• Entrances
• Reception Areas
• Retail Stores
• Offices
• Building Lobbies
• Warehouses
• Workshops
• Commercial Premises

Audio recording should always be configured and used in accordance with applicable privacy and surveillance requirements.

2.8mm & 4mm Fixed Lens Options

The DS-2CD2166G2H-ISU is available with 2.8mm and 4mm fixed lens options.

2.8mm Lens

The wider 2.8mm lens provides approximately:

• 114.8° Horizontal
• 60° Vertical
• 143.5° Diagonal

This makes the 2.8mm version particularly suitable for general surveillance where broad area coverage is required.

4mm Lens

The 4mm lens provides approximately:

• 94° Horizontal
• 50.2° Vertical
• 112° Diagonal

This provides a narrower field of view where greater concentration on a particular area is preferred.

H.265+ Video Compression

The DS-2CD2166G2H-ISU supports Hikvision's efficient H.265+ video compression technology, helping reduce network bandwidth and recording storage requirements.

Supported video compression includes:

• H.265+
• H.265
• H.264+
• H.264
• MJPEG on supported sub-stream configurations

Video bit rate is configurable from 32 Kbps to 16 Mbps.

Multiple Video Streams

The camera supports multiple simultaneous video streams, allowing different resolutions and compression settings to be configured for applications such as:

• Main NVR Recording
• Remote Viewing
• Mobile Viewing
• Secondary Monitoring
• Network Bandwidth Management

A third stream is available under supported camera configurations.

Local microSD Storage

The DS-2CD2166G2H-ISU supports onboard microSD storage, providing an additional recording option for compatible installations.

Local edge storage can be useful for:

• Standalone Camera Recording
• Event Recording
• Backup Recording
• Additional Recording Resilience
• Network Interruption Protection

PoE Connectivity

The camera supports Power over Ethernet, allowing power and network data to be delivered through a single Ethernet cable when connected to compatible PoE equipment.

This makes installation straightforward with compatible:

• Hikvision PoE NVRs
• PoE Network Switches
• Professional Network Infrastructure

A single Cat5e or Cat6 cable can therefore provide network communication and camera power.

IP67 Weather Resistance

The DS-2CD2166G2H-ISU carries an IP67 water and dust resistance rating, making it suitable for appropriately installed outdoor surveillance applications.

Typical locations include:

• Building Entrances
• Under Eaves
• Driveways
• Car Parks
• Warehouses
• Loading Areas
• Commercial Buildings
• Property Perimeters

IK10 Vandal Resistance

The fixed dome housing is also IK10 vandal resistant, providing additional mechanical protection in locations where the camera may be exposed to accidental or deliberate impact.

This makes the DS-2CD2166G2H-ISU particularly suitable for:

• Apartment Buildings
• Schools
• Retail Stores
• Commercial Buildings
• Car Parks
• Lobbies
• Common Areas
• Public-Facing Locations
• Warehouses
