4K Ultra HD Clarity with Motorized 2.8–12 mm Varifocal Zoom

The Hikvision 8 MP Motorized Varifocal Dome Network Camera is engineered for high-security commercial and industrial facilities requiring flexible field-of-view adjustment. Featuring an expansive 1/1.8" progressive scan CMOS sensor, it captures crystal-clear 4K UHD video (3840 × 2160 @ 24/25 fps) with superior low-light color performance down to 0.003 Lux. Its 2.8 mm to 12 mm motorized varifocal lens (horizontal FOV 108° to 46°) allows operators to adjust focal length and zoom remotely, tailoring coverage from wide-angle overviews to focused telephoto details without physical camera adjustment.

AcuSense Perimeter Defense and Smart Analytics

Equipped with onboard deep-learning algorithms, the dome provides proactive perimeter protection by accurately identifying critical security threats:

  • Target Classification: Precisely classifies human and vehicle targets across line crossing, intrusion, region entrance, and region exiting detection zones to reduce false alarms.
  • Face Capture: Detects and captures facial snapshots within the monitored area for efficient post-event searching and tracking.
  • 40-Meter Smart IR: High-performance 850 nm infrared LEDs illuminate dark outdoor scenes up to 40 meters without overexposing close-up objects.
  • 120 dB True WDR: Balances difficult backlighting and intense glare near glass atriums, building entrances, and parking lots.

Vandal-Resistant IK10 Construction and Comprehensive I/O

Built with a heavy-duty vandal-resistant dome enclosure rated IK10 impact-resistant and IP66 weather-resistant, the camera operates reliably in extreme temperatures from -30 °C to 60 °C. Its 3-axis gimbal (pan 0° to 355°, tilt 0° to 75°, rotate 0° to 355°) ensures straightforward alignment on ceilings or walls. Connectivity includes 3.5 mm audio line in/out with noise filtering, 1 alarm input/output, a 256 GB microSD slot, and standard PoE (802.3af, max 12.5 W) or 12 VDC power.

FAQ

What are the advantages of a motorized varifocal lens over a fixed focal lens?

A motorized varifocal lens (2.8 to 12 mm) allows you to adjust the optical zoom and focal width remotely through client software or a web browser. This eliminates the need to manually swap lenses or adjust the camera body on a ladder, allowing you to transition between a 108-degree wide overview and a 46-degree focused telephoto view effortlessly.
How does AcuSense technology minimize false alarms?

AcuSense utilizes deep-learning neural network processing to analyze moving objects in real time. It specifically categorizes humans and vehicles while ignoring harmless environmental triggers such as wind-blown foliage, falling leaves, rain, or small animals, ensuring alarm notifications and recording markers are only triggered by genuine threats.
Can this dome camera withstand physical tampering or harsh weather?

Yes. The camera is encased in an industrial-grade metal housing certified with IK10 vandal resistance (protecting against direct physical impacts) and IP66 weatherproofing (protecting against heavy rain and dust), with an operating temperature range of -30 °C to 60 °C.
What are the power options for this camera?

The camera supports standard IEEE 802.3af PoE (Class 3) with a maximum power consumption of 12.5 W, enabling single-cable network and power delivery via any standard PoE switch or NVR port. It also supports 12 VDC (± 25%) local terminal power.
