Hikvision DS-2CD2T66G2-4I Acusense 6MP EXIR Outdoor Bullet CCTV Camera Up to 80m IR
The Hikvision DS-2CD2T66G2-4I is a 6MP AcuSense outdoor bullet camera with up to 80 metres of infrared night vision. AcuSense deep learning classifies people and vehicles, so alerts and recorded events focus on real activity instead of animals, rain or moving foliage.

§ 01Overview
What the DS-2CD2T66G2-4I is
The Hikvision DS-2CD2T66G2-4I is a 6MP AcuSense outdoor bullet camera built for properties that need long-range night coverage.
The "-4I" reaches up to 80 metres of infrared, where the otherwise identical -2I reaches 60 metres, so it suits long driveways, rear yards and large open areas that a shorter IR range would leave dark.
AcuSense gen 2 deep learning is the main reason buyers choose this camera.
It classifies people and vehicles and ignores other movement, so possums, insects, rain and swaying branches stop triggering your phone, and recorded footage becomes searchable by human or vehicle events.
A 1/2.4" sensor with DarkFighter low-light tuning and 120dB WDR holds detail in high-contrast scenes such as a backlit gate or a driveway lit by headlights.
Night footage is infrared black and white, not full colour ColorVu.
It comes in 2.8mm, 4mm or 6mm fixed-lens options, so note your preferred lens in the order comment.
The IP67 metal housing handles dust and rain, a microSD card up to 256GB allows on-board recording without an NVR, and the camera runs on PoE (802.3af) or 12V DC.
It works with Hikvision AcuSense NVRs and the Hik-Connect app, and is normally fitted by a security or cabling technician.

§ 04Why choose this
Built for the way you actually use the DS-2CD2T66G2-4I
Targets real activity
AcuSense classifies people and vehicles, so animals, insects, rain and moving branches stop triggering alerts and footage stays searchable by event type.
Clear in hard light
A 1/2.4" DarkFighter sensor and 120dB WDR keep faces and plates readable against backlight, shadow and headlight glare.
Backed locally
Supplied by an authorised dealer with a 3-year Australian warranty and support.
§ 05Where it fits
Right at home in these scenarios
Long driveways and rural blocks
The 80m IR covers a long approach end to end, with AI alerts aimed at vehicles and people rather than wildlife.
Warehouse yards and boundaries
Watch a fence line or loading area at night and let AcuSense flag intruders, not blowing rubbish or rain.
Front yards and entries
A 4mm lens frames a typical front yard; faces and clothing stay clear against a backlit doorway by day.
Car parks and laneways
Use the 6mm lens for longer, narrower runs where you need reach and detail at distance.
§ 06Setup
Installation & setup
Pick your lens
Choose 2.8mm for wide coverage, 4mm for general outdoor use, or 6mm for distance, and note the choice in your order comment.
Power and cabling
Run a single Cat5e/6 cable from a PoE (802.3af) switch or NVR port, or use a 12V DC supply where PoE is not available.
Mount and aim
Fix to a wall or eave 2.5-3m high, angle down across the area to cover, and frame the view for the chosen lens.
Setup
In Australia a network camera is usually fitted by a licensed security installer or a competent IT/cabling technician, who runs the Cat5e/6 cable, terminates the RJ45, mounts the unit and adds it to the NVR or app. Add it in Hik-Connect or your NVR, then set human and vehicle detection zones.
