DH-HAC-B1A51P-U-IL-A 5MP is a 5MP Smart Dual Light HDCVI fixed-focal bullet camera built for people who want sharper resolution combined with vivid full-color night footage. Made by Dahua, this camera belongs to the Cooper Series and is well suited for homes, retail counters, and small businesses that need detailed daytime and nighttime coverage.
At the core of DH-HAC-B1A51P-U-IL-A 5MP is its 5MP resolution, capturing 2880 x 1620 pixel footage in a cinematic 16:9 aspect ratio at up to 25fps. This makes it easy to identify faces, vehicle number plates, and other important details with noticeably more clarity than standard 2MP cameras.
Smart Dual Light is where DH-HAC-B1A51P-U-IL-A 5MP truly stands out. The camera automatically switches between IR and warm white light for better nighttime visibility, with an IR distance reaching up to 30 meters, delivering clear, colored footage instead of the grainy black-and-white output typical of standard IR-only cameras.
Format flexibility is a major strength as well. DH-HAC-B1A51P-U-IL-A 5MP supports CVI, CVBS, AHD, and TVI switchable formats, giving installers genuine freedom to pair it with a wide range of existing DVR systems, such as Dahua XVR or compatible Turbo HD recorders, without needing to overhaul the whole setup.
Audio capability adds real value too. DH-HAC-B1A51P-U-IL-A 5MP includes a built-in microphone, capturing broadcast-quality audio directly over the coaxial cable, making it well suited for retail cash counters, pharmacies, and other spaces that benefit from audio recording.
Installation is refreshingly simple. The lightweight bullet housing mounts easily on any wall or pole with included screws, and a built-in switch lets installers match the camera’s output to their DVR format before connecting the BNC cable, with no IP addressing or port-forwarding required.
Durability is central to this camera’s design. With an IP67 weatherproof rating, DH-HAC-B1A51P-U-IL-A 5MP performs reliably through rain, dust, and harsh outdoor conditions without any drop in image quality.
Lens flexibility rounds out the package nicely. DH-HAC-B1A51P-U-IL-A 5MP is available with a 3.6mm fixed lens as standard, with 2.8mm and 6mm alternatives, giving installers the ability to match the field of view to the specific monitoring area.
Whether securing a home entrance or a retail counter, DH-HAC-B1A51P-U-IL-A 5MP delivers sharp 5MP clarity, Smart Dual Light deterrence, and built-in audio in one compact HDCVI bullet camera.
