High-Clarity 4 MP Surveillance with Motorized 2.8–12 mm Zoom

The Hikvision 4 MP Motorized Varifocal Bullet Network Camera provides high-resolution imaging and flexible optical coverage for commercial perimeters, parking facilities, and warehouse environments. Powered by a 1/3" progressive scan CMOS sensor, it captures crisp 2.5K QHD video (2688 × 1520 @ 25/30 fps) with low-light color sensitivity down to 0.005 Lux. Its motorized 2.8 mm to 12 mm varifocal lens (horizontal FOV 95.8° to 29.2°) allows operators to adjust focal length and zoom remotely, transitioning smoothly between broad situational overviews and detailed long-range inspection.

Long-Range Infrared Night Vision and Contrast Balance

Engineered for dependable 24/7 security in demanding lighting conditions, the camera combines long-range illumination with advanced image enhancement:

  • 60-Meter Smart IR: High-performance 850 nm infrared LEDs illuminate dark perimeters up to 60 meters in complete darkness (0 Lux) without overexposing close-up objects.
  • 120 dB True WDR: Balances difficult backlighting and direct vehicle headlight glare to preserve critical forensic details in shadows and highlights.
  • Image Optimization: Incorporates BLC, HLC, and 3D Digital Noise Reduction (DNR) to deliver clean, artifact-free video in challenging environments.

Rugged Construction and Flexible System Integration

Built for harsh environments, the camera operates reliably in extreme temperatures from -30 °C to 60 °C. Its integrated 3-axis mounting bracket (pan 0° to 360°, tilt 0° to 90°, rotate 0° to 360°) allows precise alignment on walls, ceilings, or poles. It supports local edge storage up to 512 GB via microSD, two-core terminal audio line in/out interfaces with environmental noise filtering, and 1 alarm input/output for external sensor and siren linkage.

FAQ

What are the advantages of a motorized 2.8 to 12 mm varifocal lens?

A motorized varifocal lens allows you to adjust optical zoom and focal width remotely through client software or a web browser. You can seamlessly switch between a 95.8-degree wide overview and a 29.2-degree telephoto view without having to physically open the camera or manually adjust hardware on a ladder.
How does the camera handle extreme lighting contrasts and glare?

The camera is equipped with true 120 dB Wide Dynamic Range (WDR) hardware technology. It captures and combines multiple exposures to balance bright background light and deep foreground shadows, ensuring clear facial and license plate visibility near gates, entryways, and parking areas.
What audio and alarm connectivity does this camera offer?

The camera includes two-core terminal blocks for audio line-in (with environmental noise filtering) and audio line-out to connect external microphones or speakers. It also features 1 alarm input and 1 alarm output (max. 12 VDC, 30 mA) to integrate with physical door sensors, PIR detectors, or external sirens.
How does the camera store footage during network interruptions?

The camera features an onboard memory card slot supporting microSD, microSDHC, and microSDXC cards up to 512 GB. When configured with Auto Network Replenishment (ANR), the camera automatically records video locally if the network goes down and syncs the files back to the NVR once connectivity is restored.
