Dahua IPC-MFW7849Y-Z4-T44 8+4MP Dual-Sight Polarlight Bullet WizMind Network Camera – 20‑80mm Zoom + 8‑32mm Zoom
Dual Motorized Zoom Channels – See Farther, Cover Wider
- Channel 1 (Ultra Detail – 8MP): 1/1.2" CMOS, 20‑80mm F1.1 motorized P‑Iris zoom, warm light up to 80m. Detection range up to 1,048m (3,438 ft).
- Channel 2 (Telephoto – 4MP): 1/1.8" CMOS, 8‑32mm F1.6 motorized DC‑Iris zoom, dual light fusion (IR 120m + warm 80m). Detection range up to 395m (1,296 ft).
- Dual Micro‑PTZ & Independent Area Lighting: Remotely adjust lens angles (CH1: tilt ±5°; CH2: tilt ±15°). Control lighting zones independently – 8 warm LEDs (CH1) + 2 dual‑light fusion LEDs (CH2).
- Simultaneous AI on Both Channels: CH1 and CH2 AI functions can be enabled at the same time – perimeter protection, face recognition (100,000 faces), people counting, crowd distribution map, video metadata.
- Polarlight & Time‑Division Exposure: Extreme low‑light sensitivity (CH1: 0.0003 lux color; CH2: 0.0005 lux color) plus time‑division exposure ensures clear capture of people, vehicles, and non‑motor vehicles moving at different speeds.
- Dual Light Fusion (CH2): Combines IR and warm light for multiple illumination modes while minimizing glare.
- All‑Weather Rugged Design: Glass heater for defogging, IP67 weatherproof, operating temperature -40°C to +60°C (–40°F to +140°F).
