Hikvision DS-2CD2166G2H-ISU — 6MP AcuSense Fixed Dome Camera with Built-in Mic, 30m IR & Alarm I/O

The Hikvision DS-2CD2166G2H-ISU is a professional-grade 6 MP Powered by DarkFighter AcuSense fixed dome IP camera suited to surveillance in offices, retail stores, warehouses and along perimeters. Its 1/2.4" progressive-scan CMOS sensor paired with a 2.8 mm fixed wide-angle lens produces sharp 6 MP footage over a 101° field of view, and Smart IR reaching 30 m keeps scenes clear after dark. Deep-learning AcuSense technology tells humans and vehicles apart to reduce false alarms and drives line-crossing and intrusion detection. Audio is captured through the built-in microphone, and the 1-in / 1-out alarm interface connects to external equipment. 120 dB WDR copes with strong backlighting, H.265+ compression trims storage and bandwidth use, and the tough IP67 / IK10 metal dome works indoors or out. Australian stock, 3-year Australian warranty.

Smart Detection with Audio & Alarm Integration

6 MP AcuSense Detail

With 3072 × 2048 resolution spread across a generous 101° view, the 6 MP sensor captures ample detail for offices, retail floors, warehouses and entrances — and leaves headroom to zoom into recorded footage digitally.

AcuSense False-Alarm Filtering

On-camera deep learning in AcuSense sorts motion into human, vehicle or other categories, so notifications only arrive for genuine threats. The same engine enables line-crossing and intrusion detection for proactive perimeter security.

Built-in Mic + Alarm I/O

The built-in microphone records audio in step with video, and the 1-in / 1-out alarm interface ties in external sensors, strobes and access-control gear to round out a full security system.

IP67 / IK10 All-Weather Build

Housed in a rugged metal dome rated IP67 against the weather and IK10 against vandalism, with a broad -30 °C to +60 °C operating range, the camera performs reliably inside or exposed to harsh Australian conditions.

Frequently Asked Questions

• What does AcuSense do?
  AcuSense runs deep learning on the camera itself to label motion as human or vehicle, screening out false triggers from animals, foliage and weather. It also enables line-crossing and intrusion detection for active perimeter protection.
• Does it record audio?
  Yes — a built-in microphone captures audio together with video, and the 1-in / 1-out alarm interface lets you connect external sensors and devices.
• Is it suitable for outdoor use?
  Yes. The metal dome carries IP67 weatherproof and IK10 vandal-resistant ratings and operates from -30 °C to +60 °C, so it handles both indoor and exposed outdoor mounting.
• How is it powered?
  It accepts PoE (802.3af), running over a single Cat 6 cable from a PoE NVR or switch, or 12 VDC for standalone setups.
