Key Features

• 2MP Full HD Resolution: Captures crisp and detailed video at a maximum of 30 fps@1080p, ensuring that every movement is recorded with clarity.

• Illumination Distance up to 30 m: With powerful built-in LEDs, the camera offers clear night vision up to 30 meters, making it effective for medium-range outdoor monitoring.
• Built-in Microphone: Records audio alongside video, enabling synchronized monitoring that captures conversations and sound cues for more comprehensive evidence.
• 3.6 mm Fixed Lens (Optional 2.8 mm / 6 mm): The 3.6 mm lens provides a wide field of view suitable for most monitoring needs, while the optional 2.8 mm or 6 mm lenses allow customization for different scenarios—wide coverage or focused detail.
• Four-in-One Video Output: Supports CVI, CVBS, AHD, and TVI formats, making it compatible with a wide range of DVRs and allowing flexible integration into existing systems.
• Rugged Design with IP67 Rating: Built to withstand tough outdoor environments, the camera is dust-tight and protected against heavy rain, ensuring reliable operation in all weather conditions.
• 12 VDC Power Supply: Standard power input with low consumption for efficient operation.

Performance and Technology

The 2MP CMOS image sensor ensures high-quality imaging with excellent color reproduction and reduced noise, even in challenging lighting conditions. The Smart Dual Light system is particularly beneficial as it allows the camera to switch intelligently depending on the environment. For discreet surveillance, the infrared mode provides invisible illumination. For enhanced situational awareness, the warm LED can be activated to capture vivid, full-color images during the night—helping identify people, vehicles, and objects more effectively.

Versatility in Application

The Dahua HAC-B1A21P-U-IL camera is designed to be versatile, making it suitable for:

• Residential Security: Monitor entrances, gardens, garages, or perimeter fences with clear night and day video.
• Retail and Business Use: Secure shops, offices, warehouses, and parking lots with audio-enabled monitoring.
• Public Spaces: Ideal for community surveillance, such as parks, streets, or small-scale city monitoring.
• Industrial Facilities: Rugged enough for outdoor industrial sites, ensuring around-the-clock security.

Its switchable formats (CVI/CVBS/AHD/TVI) also make it highly adaptable for new installations or upgrades to existing surveillance systems without needing to replace existing DVRs.
