The Dahua IPC-HFW5449T1-ASE-D2 is a 4 MP network bullet camera in the WizMind 5 Series, designed around a dual-sensor architecture that captures luminance and color on separate CMOS sensors. Unlike conventional IR cameras that switch to monochrome at night, the dual-sensor design preserves full color in scenes as dark as 0.0002 lux — without engaging the warm-light LEDs unless the scene drops below that threshold.

How does the dual-lens full-color system work?

Two 1/1.8″ CMOS sensors share the optical path: one captures luminance at high sensitivity, the other records chrominance. The ISP fuses both streams into a single full-color image. Because the luminance sensor needs no IR-cut filter, it collects substantially more light than a conventional single-sensor design. This architecture produces usable color video at 0.0002 lux — roughly the light level of a clear night with a quarter moon. Four IR LEDs and two warm-light LEDs provide supplemental illumination reaching 50 m when ambient light is insufficient.

What AI analytics are built in?

The camera runs Dahua's WizMind AI stack on-device. Perimeter protection with human and vehicle classification covers tripwire, intrusion, loitering, people gathering, and parking detection. Face detection extracts six attributes — gender, age, glasses, expressions, mask, and beard — across eight expression types. People counting supports entry/exit, area occupancy, and queue management with daily, monthly, and yearly reporting. SMD 3.0 filters false alarms by distinguishing vehicles, humans, and irrelevant motion.

What are the installation and environmental limits?

The metal housing is IP67-rated and operates from –40 °C to +60 °C. Power options are 12 VDC or PoE (802.3af), with ePoE support for cable runs beyond 100 m. The built-in microphone and speaker eliminate the need for external audio peripherals during two-way communication. A microSD slot supports local recording up to 256 GB, supplementing NAS and FTP/SFTP network storage. The camera measures 288.4 × 94.4 × 84.7 mm and weighs 1.0 kg.

Is this model still available?

Dahua lists the IPC-HFW5449T1-ASE-D2 among discontinued products. Distributor stock may still be available, but new projects should consider current-production WizMind 5 Series full-color models. Check with your Dahua distributor for availability and successor recommendations.
