HAC-B1A51P-U-A is a 5MP HDCVI fixed IR bullet camera built for straightforward outdoor and indoor surveillance in homes and small businesses. With a durable bullet-style housing and multi-format video output, this camera is a practical, budget-friendly choice for entrances, driveways, and perimeter monitoring.
The HAC-B1A51P-U-A captures 5MP resolution at 2880×1620 through a 5MP CMOS sensor, with a fixed 3.6mm lens (2.8mm optional) offering a 92° horizontal field of view for the standard lens. The DORI detect distance reaches 80m with the 3.6mm lens, giving reliable coverage for typical residential and small commercial settings. Low-light performance is rated at 0.02 lux, dropping to a full 0 lux with the IR illuminator active.
Night vision on the HAC-B1A51P-U-A extends up to 30m with Smart IR technology, which automatically adjusts illumination intensity to prevent overexposure of objects close to the camera while maintaining visibility further out. This keeps nighttime footage balanced and usable across the full field of view.
A standout convenience of the HAC-B1A51P-U-A is its switchable video output: CVI, TVI, AHD, and CVBS formats are all supported through a single BNC port, giving installers flexibility to match whatever recorder or DVR system is already in place. The camera also includes a built-in microphone, capturing audio alongside video for a more complete record of activity — a feature not always included at this price point.
Image quality is supported by DWDR (Digital Wide Dynamic Range) along with BLC and HLC compensation, helping the camera maintain clear detail in mixed or challenging lighting conditions like strong backlight near doorways or windows. Up to 8 configurable privacy masking areas let users block out zones that shouldn’t be recorded.
Built for outdoor durability, the HAC-B1A51P-U-A carries IP67 protection, making it well suited to withstand rain, dust, and temperature extremes. It operates across a wide -40°C to +60°C range and draws a maximum of just 3.7W with IR active, running on standard 12VDC power.
For anyone looking for a reliable, easy-to-install bullet camera with built-in audio capture and flexible format compatibility, the HAC-B1A51P-U-A offers solid, no-frills performance at an accessible price point.
