Dahua IPC-HFW8449J-Z-2712-SC 4MP IP Bullet Camera – Self-Cleaning Window, Motorized 2.7-12mm, WizMind 8

Dahua IPC-HFW8449J-Z-2712-SC is a WizMind 8 Series 4 MP bullet camera that cleans its own window: the housing holds a 2.6-litre tank, a wiper and dust-repellent coated glass. A motorized 2.7–12 mm zoom lens, 140 dB WDR and deep-learning face, vehicle and perimeter analytics make it a camera for places where an ordinary lens goes blind with dust within weeks.

Key Advantages and Features:

• Self-cleaning window: A 2.6-litre tank, quick-install wiper and dust-repellent coated glass keep the view clear. Cleaning runs manually or on a schedule, and the wiper works together with the water spray. Dahua rates a full tank for three years at one cleaning per week.
• Water level sensor: A built-in electrode probe measures the tank and reports no water (with an on-screen warning), low water level (threshold adjustable 1–50%) and full water supply.
• Smart PDS window heating: Heating switches on by itself based on ambient temperature and keeps the image clear in rain, snow or fog. The wraparound sunshield reduces dirt on the window and blocks stray light from outside the field of view.
• 4 MP large sensor and 140 dB WDR: The 1/1.8-inch CMOS delivers 2688 × 1520 at 25/30 fps. Colour images start at 0.0005 lux, and 140 dB WDR keeps both bright and dark areas readable against backlight.
• Two illumination modes up to 60 m: Four multi-core LEDs provide infrared up to 60 m and warm white light up to 40 m. Smart Dual Light switches mode to suit the scene.
• Deep-learning analytics: Face detection with face attributes, video metadata (vehicle, non-motor vehicle, human) and perimeter protection: tripwire, intrusion, fast moving, loitering, people gathering and parking detection.
• Motorized 2.7–12 mm lens: Set the field of view remotely without climbing to the camera: 92.6°–48° horizontally. A built-in gradienter shows the horizontal level during installation.
• Full set of interfaces: Two alarm inputs and outputs, RS-485, audio in and out, dual microphones and a speaker for two-way talk, microSD up to 1 TB, and a 12 V output (up to 165 mA) for an auxiliary device.
• Built for outdoors: The IP67 metal-and-plastic housing works from −30 °C to +60 °C. Power over PoE+ (802.3at) or 12 V DC with ±30% tolerance.

Technical Specifications:

Suited to dusty and dirt-prone environments — tunnels, construction sites, quarries, farms and industrial areas where the window would otherwise need cleaning by hand. Cleaning fluid is not supplied; Dahua recommends a windshield fluid rated to −40 °C.
