Overview

HIKVISION's DS-2CD2166G2-ISU packs AcuSense into a 6MP dome IP camera. Imaging comes from a 1/2.4" progressive CMOS behind an F1.6 aperture, down to 0.003 lux in colour. It is offered with a choice of fixed lens: 2.8 mm (105° horizontal) or 4 mm (78° horizontal). At night it uses IR up to 30 m.

Deep-learning perimeter rules (line crossing, intrusion, region entry/exit) classify people and vehicles, so leaves, rain and animals trigger far fewer false alarms. Audio: built-in microphone (no speaker). It is IP67 IK10 rated, powered by PoE (802.3af), with on-board microSD backup.

Ideal Use Cases

Driveways and front entries: 6MP detail for visitors, parcels and vehicles.

Side passages and backyards: Perimeter rules alert on people, not pets or moving foliage.

Shopfronts and small businesses: Clear identification at counters, doors and loading areas.

High-risk or reachable mounts: IK10 housing resists tampering and impact.

Sites needing audio evidence: Built-in mic captures sound where recording audio is lawful.

Buyer Tips

Pick the right lens. 2.8 mm gives the widest view for yards and rooms; 4 mm narrows the view for more detail on gates, doors and driveways further away.
Mount height. 2.5–3.5 m gives good identification while keeping the camera out of easy reach.
Audio law. Enable the microphone only where audio recording is lawful in your state.
Check NVR compatibility. Smart search and AcuSense filtering need a compatible Hikvision NVR and current firmware.
Budget storage. Higher resolution needs more HDD space; size the NVR drive for your retention period.
