Dahua Technology IPC-HFW3849T1-AS-PV-PRO câmara de vigilância bullet câmara de segurança IP interior e exterior 3840 x 2160 píxeis teto/parede

Dahua Technology IPC-HFW3849T1-AS-PV-PRO is a wired bullet IP security camera with an 8 MP 1/1.8" CMOS sensor producing up to 3840×2160 resolution at 25/30 fps. Designed for both indoor and outdoor installations, the camera supports ceiling or wall mounting and offers flexible power options via Power over Ethernet (PoE) or 12 VDC. The device includes built-in warm and IR illumination, dual microphones, a speaker for two-way audio, and an IP67-rated weatherproof housing suitable for commercial and residential surveillance.

Advantages

The camera provides high-resolution imaging with efficient H.265/H.264 codecs and advanced compression modes to reduce bandwidth and storage requirements. WizSense AI capabilities enable human and vehicle classification with features such as intrusion, tripwire, stay/loitering detection and full-image face detection to improve event accuracy. Integrated sound-and-light alarm with red and blue warning lights, SMD 4.0 support and multiple abnormality detections contribute to reliable, automated alerting and evidence capture. With PoE support and a compact white bullet housing, installation and integration into existing wired networks are straightforward.

Suitable for

• Perimeter monitoring for commercial properties and warehouses
• Entrance and driveway surveillance for residential homes
• Parking lots and vehicle access control points
• Indoor public areas such as lobbies and corridors
• Retail stores for loss prevention and customer flow analysis

How to use

Mount the camera on a wall or ceiling using suitable fasteners and adjust the aim to cover the desired field of view. Connect the camera to the network via an Ethernet cable; if available, use PoE to supply both data and power through a single cable, otherwise provide 12 VDC power. Configure video settings, motion/AI rules and alert thresholds through the Dahua recorder or web/management software. Insert a microSD card for local storage if required and enable event types you want recorded or alarmed.

Recommendations

Place the camera at an elevation and angle that minimize glare from direct light sources and maximize the clear view of persons or vehicles. For optimal AI detection accuracy, configure SMD warm light areas to match typical scene lighting, keep firmware updated, and store evidence on both a network recorder and microSD card when possible.
