The Dahua HAC-B1A21P 2MP HDCVI IR Bullet Camera is a reliable, high-performance surveillance solution ideal for both home and business security needs. Designed by Dahua — a globally recognized leader in video surveillance technology — this bullet-style camera delivers crisp Full HD 1080p video quality, making it an excellent choice for monitoring entryways, perimeters, yards, shops, offices, and other important areas.
At the heart of this camera is a 2-megapixel CMOS sensor that captures rich and detailed footage at a resolution of 1920×1080 pixels, ensuring that every recorded scene is clear and easy to analyze. Whether you’re checking videos on a monitor or reviewing recordings later, the visual clarity supports identification of important details like faces or license plates.
One of the standout features of the HAC-B1A21P is its Smart IR night vision capability, providing reliable performance even in complete darkness. Equipped with infrared LEDs, the camera can clearly capture images up to 20 meters (about 65 feet) at night — ideal for 24/7 surveillance around your property. This makes it especially effective for locations where lighting is limited or inconsistent.
This model uses HDCVI technology (High Definition Composite Video Interface), a solution that simplifies installation by carrying video, audio, data, and power over a single coaxial cable. That means you can use existing wiring in many cases, reducing both installation time and overall costs. HDCVI also supports long-distance, real-time transmission without loss of signal quality — a practical benefit for larger properties or extended setups.
Another practical advantage is the camera’s versatility. It supports multiple video output formats, including HDCVI, CVBS, AHD, and TVI, which allows compatibility with a wide range of DVR systems. The HD/SD switchable output also adds flexibility if you need to connect to different display devices.
The physical build of the camera is rugged and weather-resistant, with an IP67 rating that protects against dust, rain, and outdoor elements. Its compact bullet design is easy to mount on walls or ceilings, and fits well with both modern and traditional architectural styles.
Overall, the Dahua HAC-B1A21P offers a powerful mix of quality, durability, and affordability, making it a smart choice for anyone looking to enhance their security setup. Available now at Islam Computers in Tangail, this camera delivers dependable performance with the trusted quality of Dahua’s surveillance technology.
