Dahua DH-HAC-B1A21P-A 2MP HDCVI IR Bullet Camera with Audio — 1080p IR + Built-In Mic CCTV Bangladesh

The Dahua DH-HAC-B1A21P-A is the audio-equipped variant of Dahua’s reliable entry-level bullet camera — combining 2MP Full HD 1080p IR night vision with a built-in microphone that transmits real-time audio alongside video through the same coaxial cable. Ideal for shops, counters, reception areas, and perimeter monitoring where both video and audio evidence are valuable.

🎙️ Built-In Microphone — Audio Evidence Over Coax

The -A variant’s integrated microphone captures ambient audio and transmits it to compatible Dahua DVRs over the same coaxial cable used for video — no separate audio cabling required. This is particularly valuable for retail environments, reception areas, and access points where verbal interactions are part of the security record.

🔫 Bullet Design — Rugged Outdoor Coverage

The cylindrical bullet housing is engineered for directional outdoor surveillance — entrances, perimeters, parking areas, and corridors. The elongated body provides a built-in sun visor that reduces lens glare and improves image quality in direct sunlight. IP67-rated construction ensures full protection against dust and water.

🌙 Smart IR — 20m Adaptive Night Vision

The camera’s Smart IR automatically adjusts LED intensity based on target distance — preventing close subjects from being overexposed while maintaining illumination at the full 20-meter range. The True Day/Night ICR filter provides accurate color rendition in daylight and clean monochrome IR footage at night.

🔌 Multi-Format HDCVI + DWDR

CVI / TVI / AHD / CVBS switchable output ensures compatibility with all major DVR brands. DWDR (Digital Wide Dynamic Range) provides better exposure balance in challenging lighting conditions — entranceways facing bright outdoor light are a typical use case.

The Dahua DH-HAC-B1A21P-A is the smart choice for Bangladesh users who need both reliable IR night vision and audio recording in a tough outdoor bullet camera — straightforward installation, proven reliability.
