5MP Smart Dual Light Bullet Camera with Built-in Mic (2.8 mm, IP67, 20m Light, Audio-over-Coax)

Product Overview

The DHIL-B51CMN-A-28D (HAC-HFW1500CMN-IL-A) is a high-performance 5 Megapixel HD analog fixed bullet security camera engineered for commercial, perimeter, and residential video surveillance installations. Featuring advanced Smart Dual Light technology, the camera provides dynamic night surveillance by combining discreet infrared illumination with full-color warm white light. In standard dark environments, the camera monitors using covert IR LEDs; when a target is detected in the monitored zone, it automatically switches to warm white illumination to capture full-color evidentiary detail up to 20 meters (65.6 ft).

Equipped with a high-resolution 1/2.7" progressive scan CMOS sensor and a 2.8 mm wide-angle fixed lens, the camera outputs sharp 16:9 widescreen video at 5MP resolution (2880 × 1620 at 25 fps) across HDCVI, HDTVI, AHD, and standard CVBS analog formats. The unit features an integrated high-sensitivity microphone supporting broadcast-quality audio transmission over coaxial cable, DWDR (Digital Wide Dynamic Range), and 3D/2D digital noise reduction. Encased in a rugged IP67 weatherproof housing, it ensures continuous, reliable operation under severe outdoor weather conditions from -40°C to +60°C.
