Dahua B1A21P is a standard CCTV camera designed for basic surveillance needs. It uses a 1/2.7″ 2.0 Megapixel Progressive Scan CMOS sensor and supports up to 30fps at 1080P resolution. The compact design (70 mm × 149 mm) makes it easy to install in various locations. Furthermore, it supports multiple output formats, including HD-CVI, AHD, TVI, and CVBS.

For better image quality, the camera includes Smart IR, which provides infrared coverage up to 20 meters. It also features Digital Wide Dynamic Range (DWDR) and 2D Noise Reduction to enhance clarity in low-light settings. The 3.6 mm M12 fixed lens delivers a clear field of view, and its IP67 rating ensures weather resistance. Finally, it runs on DC12V power and has a durable plastic housing, making it suitable for both indoor and outdoor use.
