Detailed Features & Benefits
6MP High-Resolution Security Imaging
The Hikvision DS-2CD2T66G2-2I/4I captures
high-resolution video at up to
3200 × 1800 pixels.
This provides detailed footage for monitoring
commercial buildings, entrances, driveways,
car parks, warehouses and perimeter areas.
Powered by DarkFighter Technology
Hikvision Powered by DarkFighter technology
supports improved image quality in
challenging low-light environments.
The camera combines a
1/2.4-inch Progressive Scan CMOS sensor
with an F1.6 fixed lens to capture
detailed security footage.
When available light becomes insufficient,
infrared illumination supports
black-and-white night-time surveillance.
Hikvision AcuSense Human and Vehicle Detection
Hikvision AcuSense technology uses
deep-learning algorithms to distinguish
humans and vehicles from other moving objects.
This helps reduce unnecessary security
notifications caused by unrelated movement.
The technology is particularly useful
for entrances, driveways, car parks
and perimeter monitoring.
60m and 80m Infrared Versions
The camera is available in two
infrared illumination configurations.
The DS-2CD2T66G2-2I
provides infrared illumination
up to 60 metres.
The DS-2CD2T66G2-4I
provides infrared illumination
up to 80 metres.
Actual effective night-time visibility
depends on scene conditions,
installation height, lens selection
and surrounding surfaces.
Smart Infrared Technology
Smart IR technology helps manage
infrared illumination to improve
night-time image quality.
The system is designed to reduce
overexposure of nearby objects
under suitable operating conditions.
2.8mm Fixed Lens Option
The 2.8mm lens provides a
105.1-degree horizontal field of view.
This wider viewing angle is suitable
for monitoring entrances, building
frontages and larger nearby areas.
4mm Fixed Lens Option
The 4mm lens provides an
83.9-degree horizontal field of view.
It offers a narrower view than the
2.8mm version and can be suitable
for monitoring defined areas.
6mm Fixed Lens Option
The 6mm lens provides a
47.5-degree horizontal field of view.
This narrower lens is useful
where a more concentrated
surveillance view is required.
The lens is fixed and does not
provide motorised optical zoom.
120dB True Wide Dynamic Range
The camera features
120dB True WDR
to help balance bright and dark
areas within the same image.
This is useful for building entrances,
loading docks, shopfronts and
locations exposed to strong backlighting.
Intelligent Perimeter Protection
The camera supports intelligent
line crossing and intrusion detection.
Human and vehicle classification
helps identify relevant targets
for supported security events.
H.265+ Video Compression
Hikvision H.265+ compression
helps reduce video storage requirements
and network bandwidth consumption
when used with compatible equipment.
This supports efficient recording
of high-resolution 6MP security footage.
25fps High-Resolution Recording
The DS-2CD2T66G2-2I/4I supports
up to 25fps at 3200 × 1800
in Australian 50Hz mode.
This provides detailed video
for compatible professional
CCTV recording systems.
Multiple Video Streams
The camera supports multiple
video streams for compatible
recording and viewing systems.
Different streams can be configured
to suit recording quality,
network bandwidth and remote
viewing requirements.
IP67 Weather-Resistant Housing
The camera features
IP67-rated protection
against dust and water ingress.
This makes it suitable for
properly installed indoor
and outdoor surveillance applications.
Professional Bullet Camera Design
The fixed bullet housing is designed
for professional CCTV installations
where visible camera placement
is appropriate.
The camera can be manually positioned
during installation to monitor
the required security area.
Hikvision NVR Integration
The DS-2CD2T66G2-2I/4I is designed
for integration with compatible
Hikvision network video recorders.
Installers should confirm
that the selected NVR supports
6MP recording and the required
intelligent security functions.
