HAC-B1A21-U 2MP IR HDCVI Fixed-Focal Bullet Camera
The HAC-B1A21-U is a reliable and versatile 2MP IR HDCVI fixed-focal bullet camera, engineered to deliver crisp Full HD surveillance video both day and night. Compact, durable, and easy to install, this camera is designed to meet the security needs of small to medium-sized installations, including homes, retail stores, offices, and warehouses.
High-Definition Imaging
At the core of the HAC-B1A21-U is a 2MP CMOS image sensor, capable of producing 1080p resolution (1920 × 1080). The camera uses a progressive scanning system to deliver sharp, clear images without distortion, ensuring accurate details in both still and moving subjects. With a signal-to-noise ratio greater than 65 dB, images remain clean and vibrant even in challenging environments.
Flexible Lens Options
This bullet camera comes with multiple fixed-focal lens options—2.8 mm, 3.6 mm, and 6 mm—to suit different monitoring requirements.
- 2.8 mm lens: Wide field of view (H: 100°) ideal for monitoring entrances or open areas.
- 3.6 mm lens: Balanced coverage (H: 80°) for general surveillance needs.
- 6 mm lens: Narrower field of view (H: 43°) for focused monitoring of distant objects.
Each lens maintains an aperture of F2.0, ensuring sufficient light intake for bright, detailed images.
Excellent Low-Light Performance
The HAC-B1A21-U excels in low-light conditions with a minimum illumination of just 0.02 lux @F2.0 in color mode and 0.002 lux in B/W mode. With the IR illuminator activated, the camera achieves 0 lux performance for complete darkness monitoring. Its two IR LEDs provide a range of up to 30 meters (98.4 ft), making it effective for night surveillance in both indoor and outdoor settings.
The Smart IR technology automatically adjusts IR intensity to prevent overexposure of close objects, ensuring consistent image clarity in total darkness.
DORI Performance
The HAC-B1A21-U is evaluated using the DORI standard (EN-62676-4), which helps installers estimate effective detection distances:
- 2.8 mm lens: Detect up to 44.7 m, Recognize at 8.9 m, Identify at 4.5 m.
- 3.6 mm lens: Detect up to 55 m, Recognize at 11 m, Identify at 5.5 m.
- 6 mm lens: Detect up to 102.9 m, Recognize at 20.6 m, Identify at 10.3 m.
This makes it adaptable for both wide-area monitoring and more focused surveillance zones.
Multi-Format Video Output
The HAC-B1A21-U supports four video formats—CVI, TVI, AHD, and CVBS—selectable through a single BNC port. This ensures compatibility with a wide range of recorders, offering flexibility during upgrades or mixed-technology deployments.
Frame rates include 1080p at 25 fps (PAL) and 30 fps (NTSC) for HD formats, and 960H resolution for CVBS output, ensuring smooth video across platforms.
Smart Imaging Features
The camera incorporates essential imaging technologies for enhanced clarity:
- Day/Night (ICR): Automatically switches between color and B/W modes based on lighting conditions.
- DWDR (Digital Wide Dynamic Range): Balances exposure in high-contrast scenes.
- BLC (Backlight Compensation): Improves visibility in challenging light.
- 2D NR (Noise Reduction): Minimizes noise for cleaner, sharper images.
Rugged and Weatherproof
With an IP67 weatherproof rating, the HAC-B1A21-U is built for outdoor performance, resisting dust, rain, and harsh environmental conditions. The camera operates reliably in temperatures ranging from –40 °C to +60 °C (–40 °F to +140 °F) and in humidity levels up to 95%, non-condensing.
The compact plastic casing is lightweight yet durable, with a net weight of only 0.15 kg (0.33 lb), making it easy to mount on walls, ceilings, or vertical poles.
Power-Efficient Design
Operating on 12 VDC ± 30%, the camera consumes a maximum of just 2.8 W with IR enabled, making it highly energy-efficient.
Certifications and Reliability
The HAC-B1A21-U meets international standards for safety and electromagnetic compatibility, including CE-LVD (EN 62368-1) and CE-EMC (EN 55032, EN 55035) certifications. This ensures safe, compliant operation for both residential and commercial installations.
Conclusion
The HAC-B1A21-U 2MP IR HDCVI Fixed-Focal Bullet Camera offers a cost-effective yet powerful surveillance solution. With excellent low-light capabilities, flexible lens choices, multi-format compatibility, and durable weatherproof design, it’s ideal for diverse security applications. Whether securing small businesses, monitoring residential perimeters, or enhancing indoor surveillance, this camera delivers consistent, high-quality performance you can rely on.
