DHI-HAC-B1A51-U-IL

The Dahua DH-HAC-B1A51-U-IL (Cooper Series) is a professional 5-megapixel HDCVI bullet CCTV camera designed for high-definition surveillance in residential, commercial, and industrial environments.

It supports up to 5MP resolution (2880 × 1620), providing significantly clearer and more detailed images compared to standard 2MP cameras. The camera is compatible with multiple analog HD formats including HDCVI, AHD, TVI, and CVBS, ensuring wide DVR compatibility and easy installation.

This model features Smart Dual Light technology, combining infrared (IR) and warm white light. In low-light conditions, it normally operates in IR mode for discreet night vision, but automatically switches to white light when motion is detected, producing full-color video for improved identification and evidence quality.

It typically comes with 2.8mm or 3.6mm fixed lens options, where 2.8mm provides a wide-angle view and 3.6mm offers a more focused, longer-distance view.

Depending on the variant (especially -A / -IL-A versions), the camera includes a built-in microphone, enabling audio recording over coaxial cable when used with compatible DVR systems.

The camera is housed in a durable IP67-rated weatherproof casing, making it suitable for outdoor installations and harsh environmental conditions. It supports night illumination up to 30 meters (IR) and approximately 20 meters for white light, depending on the model variant.
