Câmara de segurança IP bullet Dahua IPC-HFW3549T1-AS-PV exterior com fios 2592×1944 30fps 98° 1/2,7 polegadas CMOS 0,003 lx montagem 360°

Dahua WizSense IPC-HFW3549T1-AS-PV is an outdoor bullet IP security camera designed for wired installations on ceilings or walls. It delivers up to 5 MP resolution (2592 × 1944) and supports video at up to 30 fps, using a 1/2.7" CMOS sensor with high sensitivity (0.003 lx). The camera provides a 98° horizontal field of view and includes a 360° rotation mounting capability for flexible positioning. Built-in AI features focus on human and vehicle detection to improve event accuracy, while H.265 compression and flexible coding options reduce bandwidth and storage requirements. The device is weather‑resistant (IP67) and supports PoE or 12V DC power supply for reliable outdoor operation.

Advantages

The camera combines high-resolution imaging with low-light performance to capture detailed footage day and night. AI-driven detection classifies humans and vehicles to reduce false alarms and speed up incident handling. Flexible video encoding (including H.265/H.265+ and ROI) lowers network load and storage needs. Onboard features such as built-in microphone and speaker, sound-and-light alarm linkage, local microSD support up to 256 GB, and robust IP67 housing make the unit suitable for perimeter and property monitoring in varied outdoor conditions.

Suitable for

• Perimeter surveillance for residential and commercial properties
• Entrance and driveway monitoring with human and vehicle detection
• Parking lots and loading areas requiring long-range observation
• Outdoor public spaces where weatherproof and continuous recording are needed

How to use

Mount the camera on a wall or ceiling using the included bracket and adjust the angle to cover the desired area; the unit supports 360° rotation at the mount for precise framing. Connect the camera to a PoE switch or provide 12 V DC power and connect to the local network via wired Ethernet. Configure video resolution, frame rate, and encoding settings in the Dahua-compatible management software or NVR. Enable WizSense detection rules to classify human and vehicle events, set tripwire or intrusion lines as needed, and configure alarm actions such as sound-and-light linkage, email notifications, or recording on event.

Recommendations

For optimal long-range detection and recognition, install the camera at an appropriate height with an unobstructed view and set the resolution to 5 MP where network and storage allow. Use PoE for simplified cabling where possible, keep firmware updated, and calibrate AI detection thresholds to the specific scene to minimize false positives. Regularly check the lens and illuminator for dirt and keep the mounting hardware tightened to maintain stable alignment.
