Dahua DH-IPC-HFW1431S1-S4 4MP IR Fixed-focal Bullet Camera

The Dahua DH-IPC-HFW1431S1-S4 4MP IR Fixed-Focal Bullet Camera is an Entry Series network camera designed to provide high-definition surveillance at an affordable price. Its bullet form factor is well suited for entrances, gates, building perimeters, retail stores, offices, warehouses, parking areas, and other indoor or outdoor locations.

The camera is equipped with a 1/3-inch 4MP progressive CMOS sensor with an effective resolution of 2688 × 1520 pixels. It supports 4MP output at 2560 × 1440 resolution at 25/30 fps and can also support maximum 4MP resolution of 2688 × 1520 at up to 20 fps.

For nighttime surveillance, the camera features 18 built-in IR LEDs with an IR illumination distance of up to 30 meters. Smart IR technology helps adjust infrared illumination to provide useful images in dark environments while helping reduce overexposure of nearby objects.

The camera uses a fixed-focal M12 lens, with 2.8mm and 3.6mm lens options. The 2.8mm lens provides a wider viewing angle for broader areas, while the 3.6mm option provides a narrower and more focused field of view.

For challenging lighting conditions, the DH-IPC-HFW1431S1-S4 supports 120dB WDR, which helps balance bright and dark areas within the same scene. It also features 3D Noise Reduction, BLC, HLC, white balance, gain control, image rotation, and mirror functions for improved image quality.

The camera supports Smart H.265+ and Smart H.264+ compression technologies, helping reduce bandwidth and storage requirements compared with conventional video encoding. ROI support allows important areas of the image to receive higher encoding priority.

For event monitoring, the camera supports motion detection, video tampering detection, network disconnection, IP conflict, illegal access, and voltage detection. These functions can help users identify security events and camera/network abnormalities.

The camera supports 12V DC and PoE (IEEE 802.3af) power. PoE allows power and network data to be transmitted through a single Ethernet cable when used with a compatible PoE switch or NVR, simplifying installation.

With an IP67 protection rating, the camera is designed to withstand dust and water exposure, making it suitable for outdoor surveillance. Its compact metal and plastic housing measures approximately 162.6 × Ø70mm and weighs around 0.22kg.

Overall, the Dahua DH-IPC-HFW1431S1-S4 is an excellent choice for customers looking for a 4MP Dahua Bullet IP Camera with 30m IR night vision, 120dB WDR, Smart Codec, PoE, and IP67 outdoor protection.
