24/7 Full-Color Surveillance in a Heavy-Duty Vandal Dome

The Hikvision DS-2CD2147G2-L(SU) is a 4 MP ColorVu AcuSense Fixed Dome Network Camera engineered for round-the-clock color surveillance in high-risk commercial spaces, schools, transit stations, retail shops, and public building exteriors. Combining a high-sensitivity 1/1.8" progressive scan CMOS sensor with an ultra-large F1.0 aperture lens, it delivers vibrant 2.5K QHD color video (2688 × 1520 @ 25/30 fps) down to 0.0005 Lux. Available in 2.8 mm (112° FOV) for expansive wide-angle monitoring and 4 mm (95° FOV) for enhanced focal identification, its 3-axis gimbal adjustment (pan 0° to 355°, tilt 0° to 75°, rotate 0° to 355°) ensures straightforward wall or ceiling mounting.

Intelligent Target Classification and Audio/Alarm Integration

Equipped with onboard deep-learning processing and flexible physical interfaces, this vandal-resistant dome provides proactive security management:

  • AcuSense Perimeter Analytics: Accurately categorizes human and vehicle targets across line crossing, intrusion, and region entrance/exiting zones, preventing nuisance alerts from moving trees, shadows, or animals.
  • Audio Security & I/O Terminals (-SU): Includes a built-in microphone with environmental noise filtering, plus dedicated terminal blocks for 1 audio line-in, 1 audio line-out, and 1 alarm input / 1 alarm output (max. 12 VDC, 30 mA).
  • 30-Meter Smart White Light: Warm supplemental light illuminates up to 30 meters in pitch-black conditions (0 Lux), preserving full-color details day and night.
  • 130 dB True WDR: Expertly balances high-contrast lighting, window reflections, and harsh direct sunlight.
  • Face Capture: Automatically detects facial features within the monitored field of view for rapid event playback and logging.

Heavy-Duty IK10 Impact Protection and Low-Power PoE

Designed to withstand physical tampering and extreme weather, the camera features an IK10 vandal-proof dome bubble and an IP67 sealed weatherproof casing operating reliably from -30 °C to 60 °C. It supports local edge storage up to 512 GB via a built-in microSD card slot and runs efficiently on standard PoE (802.3af, max 6.5 W) or 12 VDC power.

FAQ

How does ColorVu technology provide full-color video in complete darkness?

Unlike conventional security cameras that switch to black-and-white infrared night vision, ColorVu combines an advanced 1/1.8" sensor with an ultra-wide F1.0 super-aperture lens that captures four times more light. In zero-ambient-light (0 Lux) environments, the camera activates soft, warm supplemental white light up to 30 meters to maintain continuous full-color imaging.
What protection does the IK10 vandal-proof rating provide?

An IK10 rating indicates that the camera's dome bubble and housing can withstand up to 20 joules of physical impact (equivalent to a 5 kg mass dropped from 40 cm). This makes it ideal for low-ceiling public areas, transit hubs, schools, and retail corridors where physical tampering or vandalism might occur.
What are the differences between the 2.8 mm and 4 mm lens options?

The 2.8 mm lens offers an ultra-wide 112° horizontal field of view, ideal for monitoring expansive open indoor areas, reception lobbies, and store floors. The 4 mm lens provides a 95° field of view with longer recognition (up to 15 meters) and identification (up to 7 meters) distances, making it better suited for corridors, checkout aisles, and building entrances.
What additional features are included on the -SU model?

The -SU model includes an integrated built-in microphone with environmental noise filtering for ambient audio recording, as well as two-core terminal blocks for 1 audio line-in, 1 audio line-out, and 1 alarm input / 1 alarm output (max. 12 VDC, 30 mA) to connect external sensors or sirens.
