Product Description

The Dahua IPC‑HDW1431S 4 MP network camera delivers crystal‑clear imagery for both daylight and low‑light environments, making it an ideal choice for small‑to‑mid‑size security applications across Bangladesh. Its 1/3” 4 Megapixel CMOS sensor captures every detail, while the Smart Codec technology cuts bandwidth and storage needs by up to 70 %, allowing you to store more footage on less expensive hardware.

With a 2.8 mm fixed lens (3.6 mm optional), the camera offers a wide 104° horizontal field of view, perfect for covering large areas such as parking lots, storefronts, or residential perimeters. The built‑in Smart‑IR feature ensures reliable night vision up to 30 m without the common “white‑out” problem, keeping your surveillance clear even when the lights are on.

Intelligent analytics give you peace of mind: tripwire alerts, intrusion detection, and tamper alerts trigger instant notifications, so you can respond quickly to suspicious activity. The camera’s robust 120 dB WDR balances bright and dark scenes, while the 90° image‑flip option lets you mount the unit in any orientation for optimal coverage.

Designed to thrive in extreme temperatures from –30 °C to +60 °C and high humidity, the IPC‑HDW1431S is a durable, low‑maintenance solution. PoE support simplifies installation by eliminating separate power cables, and ONVIF certification guarantees compatibility with your existing video management system.

Whether you’re securing a small shop, a residential building, or a corporate office, this Dahua camera combines high‑resolution imaging, advanced analytics, and cost‑effective performance—all at a competitive price point in Bangladesh. Invest in reliable security that protects what matters most.
