Telecamera di sorveglianza Dahua IPC-HFW2449T-AS-IL-0360B 4MP Bullet

Camera with 1/2.9" CMOS sensor delivering up to 2688 × 1520 resolution. The fixed-focal 3.6 mm lens (M12 mount) provides an 84° horizontal field of view and a close focus distance of 1.7 m. The device includes 128 MB ROM and 128 MB RAM, progressive scanning, automatic/manual electronic shutter from 1/3 s to 1/100,000 s, and minimum illumination down to 0.006 Lux (color) or 0.0006 Lux (B/W); IR and warm-light illumination provide visibility up to 60 m and 50 m respectively. The camera supports pan 0°–360°, tilt 0°–90° and rotation 0°–360° for flexible installation.

Advantages

The camera supports H.265/H.264 video compression with Smart H.265+ and Smart H.264+ codecs to reduce bandwidth and storage. Dual-stream output and multiple resolution options up to 4M enable adaptable recording settings. Built-in microphone, smart illumination, wide dynamic range (120 dB) and 3D noise reduction improve image and audio capture in varied lighting. Perimeter protection (intrusion and tripwire) with vehicle and human classification and Smart Search integration with Smart NVR simplify event detection and review. Robust network support includes ONVIF profiles, IPv6 and common streaming protocols for integration with third-party systems.

How to use

Install the camera on a stable surface or mount, connect power via 12 VDC or PoE (802.3af) and connect to the network using the RJ-45 port. Configure network and video settings through the device web interface or supported management software (SmartPSS Lite, DSS, DMSS). Adjust image orientation, ROI and exposure in the interface; enable smart illumination and perimeter protection if required. For recording, set up storage to FTP/SFTP or insert a Micro SD card (up to 256 GB). Integrate with NVR or third-party systems using ONVIF or provided SDK/API.

Recommendations

For reliable outdoor performance, mount the camera under an overhang or use a weatherproof housing if installed in exposed locations. Use PoE for simplified cabling and ensure firmware is up to date to maintain cyber security features and protocol compatibility.
