Hikvision DS-2CD2T66G2H-2I 6 MP ColorVu Hybrid Bullet Camera, 60 m IR (Black & White)
The Hikvision DS-2CD2T66G2H-2I is a 6 MP ColorVu Hybrid bullet that keeps full colour in low light and falls back to 60 m infrared in the dark. AcuSense filters alerts to people and vehicles, and a bright F1.0 lens with 120 dB WDR holds detail in tricky lighting. Available in a black or white housing.

§ 01Overview
What the DS-2CD2T66G2H-2I is
The Hikvision DS-2CD2T66G2H-2I is a 6 MP ColorVu Hybrid bullet built for dependable colour-and-infrared night vision on a sensible budget.
A 1/2.4" sensor with a bright F1.0 lens captures sharp 6 MP (3200 x 1800) images, and 120 dB Wide Dynamic Range balances bright and shaded areas in the same frame, such as a sunlit forecourt against a shaded entry.
Its hybrid lighting is the difference from a plain infrared camera.
The camera holds full colour as light fades using a warm supplement light, and switches to infrared up to 60 m when it gets truly dark, so you get colour where there is some ambient light and a clear black-and-white image in full darkness.
AcuSense deep learning runs on the camera, classifying people and vehicles and triggering perimeter rules such as line crossing and intrusion only on those targets, which cuts the false alarms that branches, rain and animals cause on a basic motion camera.
H.265+ compression keeps the high-resolution stream efficient on bandwidth and storage.
This is the -2I variant, with infrared to 60 m; the -4I variant reaches 80 m for longer perimeters.
It is a metal bullet rated IP67 against dust and water, offered in a black or white housing, with a fixed 2.8 mm or 4 mm lens and a microSD slot up to 512 GB.
It runs on PoE (802.3af) or 12 VDC.
Record it to a Hikvision AcuSense NVR so the people and vehicle events stay quick to search.

§ 04Why choose this
Built for the way you actually use the DS-2CD2T66G2H-2I
Fewer false alarms
AcuSense classifies people and vehicles, so alerts come from real targets, not weather and animals.
Black or white to suit the site
Two housing colours let you match a facade or keep the camera discreet.
Efficient on storage
H.265+ compression keeps the 6 MP stream light on bandwidth and recorder space.
§ 05Where it fits
Right at home in these scenarios
Driveways and front yards
Cover the approach to a home in colour at dusk and clear infrared at night.
Retail exteriors and loading bays
Watch storefronts and rear doors with people and vehicle filtering.
Home and apartment security
Mount it on walls and soffits around doors, garages and walkways in a matching colour.
Car parks and laneways

§ 06Setup
Installation & setup
What's in the box
One DS-2CD2T66G2H-2I bullet camera with a mounting template, fixings and a quick guide. The PoE switch or NVR, network cable, microSD card and any junction box are supplied separately.
Installation requirements
Mount it on a wall or eave aimed along the area to cover, and run one network cable back to a PoE (802.3af) switch or NVR, or use 12 VDC. Set the AcuSense rules and the lighting mode in the software, and record it to a Hikvision AcuSense NVR. A junction box tidies the cabling on a flat wall.

§ 09Bundles
Recommended packages
Record and review it
Feed it to a Hikvision AcuSense recorder such as the 8-channel DS-7608NI-M2/8P, or the 16-channel DS-7616NI-M2/16P for larger sites. Add a surveillance-grade drive like the 8 TB for weeks of continuous footage.
Power it over one cable
Run a single network cable per camera from a PoE source. The HiLook 8-port PoE switch feeds several cameras and the recorder, keeping the cabling tidy on multi-camera sites.
Mount it cleanly
A DS-1260ZJ junction box tidies the cabling and screw runs behind the bullet and gives a neat finish on a wall or eave.
