4MP Imaging with F1.0 Fixed-Focal Lens
The Dahua DH-IPC-HFW3449T1-AS-PV is a 4MP Smart Dual Light Active Deterrence fixed-focal bullet WizSense network camera. It uses a 1/2.7-inch CMOS sensor and delivers images up to 2688 × 1520 at 25/30 fps. The camera is available with a 2.8 mm or 3.6 mm fixed-focal lens, with a maximum F1.0 aperture to support image capture in low-light monitoring environments.
Smart Dual Light and Active Deterrence
The camera combines IR and warm-light illumination, with an illumination distance of up to 30 m for each light source. When a target is detected, the smart dual-light function can activate warm light for full-color event recording. For deterrence, the camera supports red and blue warning lights, sound alarms, customized voice messages, and a built-in speaker. The built-in dual microphone and speaker also support two-way talk.
AI-Based Perimeter Protection
Intelligent monitoring functions include intrusion, tripwire, stay detection, loitering detection, and full-image face detection. Intrusion and tripwire functions support human and vehicle classification to help focus event detection on relevant targets. SMD 4.0 helps distinguish human and vehicle targets from other moving objects, while AcuPick works with compatible backend devices to help locate target events in live and recorded video.
