DAHUA IPC-HFW3849T1-ZAS-PV-2712-PRO Câmara IP Bullet 8MP com dissuasão ativa, objetiva varifocal motorizada e visão noturna a cores

The DAHUA IPC-HFW3849T1-ZAS-PV-2712-PRO stands apart from conventional IP cameras by combining 8MP ultra-high-definition imaging with proactive security features. Unlike standard surveillance devices that merely record events, this TIOC 3.0 camera actively deters intruders using a built-in red/blue strobe light and siren, while its warm-light illumination delivers full-colour video even in complete darkness. The motorized 2.7–12mm varifocal lens allows remote zoom and focus adjustments, ensuring optimal coverage for a wide range of scenarios.

Highlights

• 8MP (3840×2160) resolution on a 1/2.8" progressive CMOS sensor for crisp, detailed footage.
• Active deterrence with red/blue flashing light and siren, triggered by AI-powered perimeter protection or manually.
• Full-colour night vision up to 50m via built-in warm LEDs—no separate illuminator required.
• Motorized varifocal lens (2.7–12mm, F1.4) with remote zoom/focus and 111°–47° horizontal field of view.
• Smart AI: SMD 4.0 human/vehicle classification, tripwire and intrusion detection, Quick Pick, and AI SSA.
• Built-in microphone and speaker for two-way audio; supports audio I/O and alarm I/O.
• IP67 weatherproof and IK10 vandal-resistant housing for reliable outdoor operation.
• Flexible storage: Micro SD card slot up to 256GB, plus network recording options.
• Power over Ethernet (802.3af) or 12V DC for simple installation.

In daily use

Deploy this camera at entrances, perimeters, or parking areas and benefit from its intelligent detection. When a person or vehicle crosses a virtual line or enters a defined zone, the camera can instantly flash its red/blue lights and sound a loud siren, often stopping incidents before they escalate. Simultaneously, you receive real-time alerts with snapshots or video clips. The built-in speaker allows you to issue verbal warnings remotely via the mobile app. At night, the warm LEDs illuminate the scene in full colour, capturing critical details like clothing or vehicle colour that infrared cameras miss. The varifocal lens lets you adjust the viewing angle on-site without climbing a ladder—simply use the web interface or app to zoom and focus. With H.265 compression, you save bandwidth and storage while maintaining high video quality. The rugged metal housing withstands harsh weather and tampering, ensuring years of dependable service.
