6MP High-Resolution Imaging

The DS-2CD2T66G2H-2I/4I captures surveillance footage at a maximum resolution of:

3200 × 1800

At full 6MP resolution, the camera supports up to:

20fps @ 3200 × 1800

For Australian 50Hz systems, it also supports up to:

25fps @ 2688 × 1520

as well as 1920 × 1080 and 1280 × 720.

The 6MP resolution provides an excellent balance between image detail, recording storage and network bandwidth.

High-resolution footage can assist when reviewing:

• People
• Clothing
• Vehicles
• Driveways
• Building Entrances
• Property Activity
• Commercial Areas
• Objects
• Security Incidents

Powered-by-DarkFighter Technology

The DS-2CD2T66G2H-2I/4I incorporates Hikvision's Powered-by-DarkFighter technology, designed to provide excellent image performance under challenging low-light conditions.

Hikvision specifies minimum illumination of:

Colour: 0.001 Lux @ F1.0, AGC ON

B/W: 0 Lux with IR

This makes the camera particularly suitable for areas where ambient lighting is limited.

Ultra-Wide F1.0 Aperture

The camera features an ultra-wide F1.0 aperture, allowing more available light to reach the image sensor.

Combined with Powered-by-DarkFighter technology, the bright F1.0 optics help improve low-light image quality and retain valuable image detail.

Typical applications include:

• Long Driveways
• Car Parks
• Warehouses
• Building Perimeters
• Commercial Properties
• Loading Areas
• Industrial Sites
• Low-Light Outdoor Areas

Deep-Learning Human & Vehicle Classification

The DS-2CD2T66G2H-2I/4I uses deep-learning technology to classify supported security targets as:

• Humans
• Vehicles

This allows supported security events to focus on important targets instead of treating all movement within the scene equally.

It can help reduce unnecessary security events caused by:

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

Intelligent Motion Detection

Motion detection supports alarm triggering according to specified human and vehicle target types.

When correctly configured with a compatible Hikvision NVR or surveillance platform, this can help improve:

• Event Accuracy
• Security Notifications
• Recorded Event Searching
• CCTV Monitoring Efficiency

Intelligent Perimeter Protection

The camera supports intelligent perimeter functions including:

• Line Crossing Detection
• Intrusion Detection
• Region Entrance Detection
• Region Exit Detection

These events support alarm triggering according to specified human and vehicle targets.

Professional installers can use these functions to monitor:

• Driveways
• Gates
• Property Boundaries
• Building Perimeters
• Restricted Areas
• Car Parks
• Loading Areas
• Commercial Sites

Face Capture

The DS-2CD2T66G2H-2I/4I also supports face capture.

Face capture should not be confused with facial recognition. The camera can capture facial images, while identification against a face database requires compatible back-end equipment and appropriate system configuration.

120dB True Wide Dynamic Range

The camera incorporates 120dB True WDR, helping retain useful image detail when bright and dark areas appear simultaneously within the monitored scene.

This is particularly useful around:

• Building Entrances
• Warehouse Doors
• Garage Entrances
• Loading Areas
• Covered Driveways
• Areas Facing Bright Daylight
• High-Contrast Indoor/Outdoor Scenes

Long-Range Smart IR Night Vision

One of the strongest features of the DS-2CD2T66G2H series is its extended infrared night vision.

The camera uses 850nm infrared illumination with Smart Supplement Light technology.

DS-2CD2T66G2H-2I

Provides Smart IR illumination up to:

60 metres

DS-2CD2T66G2H-4I

Provides extended Smart IR illumination up to:

80 metres

This makes the full-size bullet camera particularly suitable for applications where longer night-time coverage is required.

2I vs 4I

DS-2CD2T66G2H-2I

• Up to 60m Smart IR
• Lower maximum power consumption
• Ideal for medium-to-long-range outdoor surveillance

DS-2CD2T66G2H-4I

• Up to 80m Smart IR
• Extended night-time surveillance distance
• Ideal for larger sites and longer perimeter areas

The correct version should be selected according to the required surveillance distance and installation environment.

Ideal Long-Range Applications

The extended IR performance makes this camera particularly suitable for:

• Long Driveways
• Large Residential Properties
• Car Parks
• Warehouses
• Industrial Sites
• Commercial Yards
• Loading Areas
• Building Perimeters
• Property Boundaries
• Rural Properties

2.8mm & 4mm Fixed Lens Options

The DS-2CD2T66G2H-2I/4I is available with 2.8mm and 4mm fixed lens options.

2.8mm Lens

Approximate field of view:

• Car Parks
• Yards
• Wide Perimeter Areas
• General Outdoor Surveillance

4mm Lens

Approximate field of view:

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

The 4mm lens provides a narrower field of view for more concentrated surveillance.

DORI Distance

Hikvision specifies approximate DORI distances of:

2.8mm Lens

• Detect: 64m
• Observe: 25m
• Recognise: 12m
• Identify: 6m

4mm Lens

• Detect: 77m
• Observe: 30m
