Product Description
DS-2CD2166G2-ISU(2.8MM)(C) — spec summary
A 6MP fixed dome from Hikvision's AcuSense range, built around the DarkFighter low-light sensor and fitted with a 2.8mm fixed lens. IR range is rated to 30m, giving usable night coverage for entrances, corridors and general perimeter dome positions without supplementary lighting.
AcuSense processing runs human/vehicle classification at the edge, cutting false triggers from foliage, weather and small animals before they hit your VMS or NVR — relevant when sizing alarm workflows across a mixed estate of AcuSense-generation cameras.
Power and I/O
- Dual power input: 12 VDC or PoE — plan PSU or switch budgets accordingly on multi-camera runs.
- Audio and alarm I/O on board, so two-way audio and external alarm devices can be wired directly without a separate encoder.
- 3-year manufacturer warranty.
