IP security camera DAHUA IPC-HDW1639T-A-IL-0280B-S6 — 8MP, 2.8mm fixed lens, IR 30 m, IP67, PoE

DAHUA IP security camera with 8 MP 1/2.7" CMOS sensor and fixed 2.8 mm lens. The bullet-style metal housing is rated IP67 for outdoor use and supports wired RJ-45 (10/100) network connectivity with Power over Ethernet (IEEE 802.3af) or 12 V DC power. The camera records up to 2560 × 1440 at 25/30 fps, offers built-in IR illumination up to 30 m, on-board microphone and speaker for two-way audio, and supports local storage on MicroSDHC cards up to 256 GB. Additional features include human detection, progressive scan, D-WDR and 3D-DNR image enhancement, and web-based management.

Advantages

The camera provides high-resolution 8 MP video with 2.8 mm fixed lens for wide coverage, robust weatherproof metal housing (IP67) for outdoor installation, and flexible power options including PoE. Integrated IR night vision to 30 m and image enhancement technologies (D-WDR, 3D-DNR) improve image clarity in low light. Built-in microphone and speaker enable two-way audio, while human detection and web management simplify monitoring and configuration.

Suitable for

• Outdoor perimeter and entrance surveillance

How to use

Mount the camera on a wall or ceiling using appropriate fixings and orient the fixed 2.8 mm lens toward the area to be monitored. Connect the device to the network using the RJ-45 port; supply power via PoE (IEEE 802.3af) or a 12 V DC adapter. Access the built-in web server or mobile app (Android supported) to perform initial setup, adjust image settings including shutter speed and flip/mirror, enable human detection and configure recording or storage on a MicroSDHC card. Use the web-based management interface to manage users (up to six concurrent users) and set streaming or recording parameters.

Usage recommendations

The camera is intended for wired installations; use PoE for simplified cabling where available. For reliable night performance, ensure the IR LEDs have a clear field of view up to 30 m. Regularly check firmware and configure user access rights and detection settings to reduce false alerts.
