Description

Dahua HAC-B1A51P 5MP HDCVI IR Bullet Camera

Designed for commercial and residential exterior installations seeking higher optical detail than standard 1080p Full HD over traditional analog infrastructure, the Dahua HAC-B1A51P delivers true 5-megapixel resolution ($2880 \times 1620$) at up to 25 frames per second over standard coaxial or UTP cabling. Unlike older 4:3 5MP formats that cause stretching on modern monitors, the camera outputs a native 16:9 aspect ratio video stream that preserves true-to-life proportions without distortion.

The camera's optical core is offered with two fixed focal length options: an ultra-wide 2.8mm lens delivering an expansive $106.0^\circ$ horizontal field of view ($125.0^\circ$ diagonal) for wide perimeter coverage, or a standard 3.6mm lens ($88.0^\circ$ horizontal FOV) tailored for driveways, entry gates, and boundary corridors. The integrated 3-axis mounting bracket allows full manual adjustment ($360^\circ$ pan, $90^\circ$ tilt, $360^\circ$ rotation) for surface installation on outdoor walls, ceilings, or overhang soffits.

In zero-lux pitch darkness, the camera utilizes an integrated infrared illuminator delivering Smart IR illumination up to 20 meters (66 ft). The Smart IR controller dynamically balances infrared emission to prevent blinding or overexposing human faces and reflective vehicle license plates as targets approach the lens. Contrast and clarity under difficult lighting are enhanced using Digital WDR (DWDR), 2D Noise Reduction (2D NR), Backlight Compensation (BLC), and Highlight Compensation (HLC).

Constructed inside an all-weather IP67-certified weather-sealed enclosure made from durable engineering plastic, the camera operates reliably against torrential monsoon rains, airborne dust, and high humidity across temperatures from –40 °C to +55 °C. The camera features a 4-in-1 switchable BNC output compatible with HDCVI, AHD, TVI, and CVBS legacy formats, ensuring backward compatibility with third-party DVRs and older coaxial installations. Power is supplied through standard 12V DC.
