24/7 Full-Color 4 MP Clarity and Active Deterrence

The Hikvision 4 MP ColorVu Fixed Bullet Network Camera combines high-definition 2.5K imaging with active on-site deterrence to secure commercial and residential perimeters. Featuring a large 1/1.8" progressive scan CMOS sensor and an ultra-large F1.0 aperture lens, it collects maximum ambient light to deliver sharp, full-color video (2688 × 1520 @ 25/30 fps) down to 0.0005 Lux. In zero-ambient-light conditions (0 Lux), built-in smart supplemental warm white light illuminates targets up to 60 meters, preserving essential color details like clothing and vehicle paint without infrared washout.

Active Strobe & Siren Alarm with Two-Way Audio

Equipped with proactive deterrence hardware, the camera stops potential security breaches before damage occurs:

  • Active Voice & Light Alarm: Automatically triggers a bright flashing white strobe and custom audible warnings via the integrated 2 W speaker (97 dB at 10 cm) upon security events.
  • Two-Way Voice Communication: Features an integrated microphone with environmental noise filtering and built-in speaker for real-time talkdown, supported by external audio line in/out terminals.
  • Face Capture & Scene Analytics: Supports onboard face detection and facial snapshot capture alongside smart linkage actions.
  • 130 dB True WDR: Preserves foreground and background details in harsh backlit entryways, parking lots, and glass facades.

Heavy-Duty Weatherproofing and Flexible Deployment

Housed in an IP67-rated weather-resistant enclosure, 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 angle adjustment. The camera supports onboard microSD storage up to 512 GB, 1 alarm input/output, and standard network connectivity with iVMS-4200 and Hik-Connect client support.

FAQ

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

ColorVu technology combines a 1/1.8" high-sensitivity sensor with an F1.0 super-aperture lens that admits significantly more light than conventional security lenses. In total darkness (0 Lux), built-in supplemental warm white LEDs provide illumination up to 60 meters, maintaining true color evidence without relying on black-and-white infrared.
How does the camera actively deter intruders?

When a configured security event occurs, the camera automatically triggers its built-in flashing white strobe light and broadcasts a siren or pre-recorded voice warning through its integrated 97 dB speaker to warn off unauthorized individuals immediately.
Which lens option is suitable for my installation?

The camera is available in three fixed focal options: 2.8 mm provides an ultra-wide 111.9° horizontal field of view for broad property and yard coverage; 4 mm offers a balanced 95.2° view for driveways and fence perimeters; and 6 mm delivers a narrower 58.4° view optimized for long-distance observation up to 45.9 meters.
Does the camera support two-way audio communication?

Yes. The camera is equipped with both a built-in microphone (with environmental noise filtering) and a built-in speaker, allowing direct two-way voice communication via the Hik-Connect mobile app or iVMS-4200 software. It also includes 1 line-in and 1 line-out terminal block for external audio integration.
