The 4 mm frames tighter at \u003cstrong\u003e87° horizontal FOV\u003c\/strong\u003e, so each pixel covers less scene and detail at 10-25 m improves. Sensor, IR range and AcuSense AI are identical on both.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is Black only offered in 2.8 mm?\u003c\/strong\u003e\u003cbr\u003eHikvision produces the black finish only as the 2.8 mm SKU (DS-2CD2T66G2H-4I-BLK). If you need a 4 mm camera in black, there are alternative black-finish Hikvision bullets in the same 6 MP range that may fit the requirement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need a special PoE switch?\u003c\/strong\u003e\u003cbr\u003eNo — it's \u003cstrong\u003ePoE 802.3af Class 3\u003c\/strong\u003e (max ~8 W), so any standard Hikvision NVR PoE port or generic 802.3af switch will power it. It also accepts 12 VDC for legacy or off-grid setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes AcuSense really cut false alarms?\u003c\/strong\u003e\u003cbr\u003eYes — a typical reduction is \u003cstrong\u003e80-90 %\u003c\/strong\u003e compared with a motion-only camera. Targets are classified as human, vehicle or \"other\" before any alarm fires, so rain, foliage, insects, animals and passing headlights are filtered out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the actual IR range in practice?\u003c\/strong\u003e\u003cbr\u003eHikvision's \u003cstrong\u003e80 m\u003c\/strong\u003e rating assumes ideal conditions (dark sky, no ambient reflection). In a real Australian suburban setting with some street glow, plan on \u003cstrong\u003e50-70 m\u003c\/strong\u003e of usable IR — still among the longer distances in the 6 MP class at this level.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I integrate with a non-Hikvision VMS?\u003c\/strong\u003e\u003cbr\u003eYes — the camera supports \u003cstrong\u003eONVIF Profile S, G and T\u003c\/strong\u003e plus RTSP, and works with Milestone XProtect, Genetec, Exacq, Immix and most other VMS platforms used in Australia. Full AcuSense metadata indexing, however, is only available on Hikvision NVRs.\u003c\/p\u003e\n\u003ch2\u003eOrdering Options\u003c\/h2\u003e\n\u003cp\u003eSimply choose your preferred lens (2.8 mm wide-angle or 4 mm narrower-view) and finish (White or Black — Black is available in 2.8 mm only) when adding the \u003cstrong\u003eDS-2CD2T66G2H-4I\u003c\/strong\u003e to your order. Every unit is covered by a 3-year Australian warranty.\u003c\/p\u003e\n","brand":"Hikvision","offers":[{"title":"White \/ 2.8mm (101° Wide Angle)","offer_id":43038435442759,"sku":"DS-2CD2T66G2H-4I","price":267.0,"currency_code":"AUD","in_stock":true},{"title":"White \/ 4mm (87° Narrower View)","offer_id":43038435475527,"sku":"DS-2CD2T66G2H-4I-4MM","price":267.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ 2.8mm (101° Wide Angle)","offer_id":43038435508295,"sku":"DS-2CD2T66G2H-4I-BLK","price":267.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/0182\/9703\/files\/hikvision-ds-2cd2t66g2h-4i-6mp-darkfighter-bullet-camera.webp?v=1785813852","url":"https:\/\/aarasecuritysolution.com.au\/products\/hikvision-ds-2cd2t66g2h-6mp-darkfighter-acusense-bullet-camera","provider":"Aara Security Solution","version":"1.0","type":"link"}
