Product Description

The Dahua HAC-B1A51P is a high-definition 5MP HDCVI IR bullet camera, designed to deliver exceptional video clarity in both day and night conditions. With support for up to 25 frames per second at 5MP resolution in a 16:9 aspect ratio, this camera offers smooth, widescreen video suitable for modern surveillance setups.

Fitted with a 3.6mm fixed lens, the camera delivers a wide field of view (D: 104°, H: 88°, V: 46°), making it ideal for securing outdoor areas such as driveways, entry gates, or building perimeters. Its Smart IR technology automatically adjusts infrared intensity to prevent overexposure, ensuring clear visibility up to 20 meters in complete darkness.

Built for durability, the IP67-rated weatherproof housing makes the HAC-B1A51P resistant to dust, rain, and extreme environmental conditions. It also uses HDCVI technology, allowing for HD video transmission over long distances via coaxial cable—perfect for retrofitting existing analog systems without re-cabling.
