Bullet IP security camera DAHUA WizSense IPC-HFW3549T1-ZAS-PV — 2592×1944, wired, ceiling/wall mount, indoor/outdoor, 30 m night vision

DAHUA WizSense IPC-HFW3549T1-ZAS-PV is a wired bullet IP security camera designed for indoor and outdoor use. It uses a 5 MP 1/2.7" CMOS sensor to record up to 2592 × 1944 resolution, supports ceiling or wall mounting, and provides night vision up to 30 m. The camera integrates Dahua's WizSense AI features for accurate human and vehicle detection and includes built-in warm light, IR illumination and sound-and-light active deterrence.

Advantages

The camera offers AI-powered SMD 4.0 for reduced false alarms and Quick Pick support with compatible NVRs, smart dual light that captures full-color images when a target is detected while limiting light pollution, and siren-and-light active deterrence with customizable voice alerts. It supports H.265/H.264 codecs for efficient storage and transmission, wide voltage tolerance and IP67-rated weather protection for reliable outdoor operation. Cyber security measures include authentication, encrypted transmission and storage.

Suitable for

• Perimeter surveillance of homes and small businesses
• Entrances, driveways and parking areas for human and vehicle detection
• Indoor monitoring of corridors and lobbies where two-way audio is needed
• Outdoor sites with variable power supply and exposure to dust or rain

How to use

Mount the camera on a ceiling or wall using appropriate anchors for the chosen surface, ensuring the field of view covers the monitored area. Connect the camera to a PoE switch or a 12 VDC power supply and to your wired Ethernet network. Configure the device through Dahua’s client software or mobile app: set resolution and frame rate, enable SMD 4.0 for human/vehicle filtering, configure alarm inputs/outputs and import custom voice files for the siren-and-light deterrence if required. Insert a supported microSD card for local recording or connect to an NVR for centralized storage and Quick Pick AI search.

Recommendations

Place the camera at an appropriate height and angle to ensure accurate human and vehicle classification; keep warm light aimed to avoid direct glare into neighboring properties. For reliable night color imaging, enable Smart Dual Light and test audio deterrence messages before final deployment. Use PoE where possible to simplify installation and ensure stable power, and keep firmware updated to maintain cybersecurity protections.
