Description

Dahua HAC-B1A21P-U-IL-A 2MP Smart Dual Light HDCVI Bullet CC Camera

Designed for cost-effective analog HD retrofits and exterior commercial installations requiring round-the-clock visual evidence alongside synchronized ambient audio, the Dahua HAC-B1A21P-U-IL-A delivers genuine 2-megapixel 1080p Full HD resolution ($1920 \times 1080$) at up to 30 frames per second over standard coaxial or UTP cabling.

The primary operational highlight of the camera is Dahua's Smart Dual Light mechanism. Operating in synchronization with an AI-enabled XVR (equipped with SMD Plus or Perimeter Protection), the camera stays in discreet infrared mode under pitch-black darkness to conserve power and minimize light pollution. When a human or vehicular target breaches the designated detection boundary, the camera triggers its warm white supplemental LEDs, delivering full-color video to capture crucial evidentiary details like clothing colors, vehicle paint shades, and facial features. Once the target leaves the zone, the camera automatically reverts to infrared illumination.

The optical core is offered with two fixed-focal choices: an ultra-wide 2.8mm lens delivering an expansive $100.0^\circ$ horizontal field of view ($117.0^\circ$ diagonal) for wide perimeter overviews, or a focused 3.6mm lens ($80.0^\circ$ horizontal FOV) tailored for driveways, entry gates, and narrow property boundaries. The integrated 3-axis mounting bracket allows flexible manual orientation ($360^\circ$ pan, $90^\circ$ tilt, $360^\circ$ rotation) for surface mounting on exterior walls or overhang soffits.

In addition to high-definition video capture, the camera incorporates a built-in high-sensitivity microphone. Utilizing Dahua HDCVI audio-over-coaxial architecture, it transmits clean audio signals directly over the same coaxial cable as video without requiring supplementary audio cabling. The camera also features a 4-in-1 switchable BNC output compatible with HDCVI, AHD, TVI, and CVBS formats, ensuring backward compatibility with older DVR equipment.

Engineered inside an all-weather IP67-certified weather-sealed enclosure, the camera withstands heavy tropical monsoon rains, fine airborne dust, and high humidity across temperatures from –40 °C to +60 °C. Image balance across difficult lighting conditions is stabilized using Digital WDR (DWDR), 2D Noise Reduction (2D NR), Backlight Compensation (BLC), and Highlight Compensation (HLC).
