Dahua IPC-HFW2431SP-S 4MP WDR IR Bullet Camera

Dahua IPC-HFW2431SP-S 4MP WDR IR Bullet Network Camera When reliability matters more than flashy features, the Dahua IPC-HFW2431SP-S delivers exactly what most homes, small businesses, and budget-conscious installers across Bangladesh actually need — sharp 4MP resolution, solid Starlight low-light performance, intelligent IVS detection, and a rugged IP67 weatherproof build that can take on years of outdoor exposure without complaint. This is a Lite Series camera, and that matters in the best possible way. Lite doesn’t mean compromised; it means well-engineered, purpose-built, and priced accessibly without cutting corners where it counts. The 1/3″ CMOS sensor with Starlight technology captures surprisingly clear, color-tinted footage at just 0.008 Lux — meaning usable images under minimal ambient light like a distant streetlamp or moonlight reflection, not just pitch-black IR footage. When darkness wins completely, the built-in IR LED takes over with up to 30 meters of illumination, automatically adjusting intensity to prevent overexposure on nearby subjects. For buyers in Bangladesh — whether you’re a homeowner in Dhaka’s residential areas, a shop owner in Chittagong, or an installer putting together a small commercial system in Sylhet — the IPC-HFW2431SP-S is one of the most dependable entry points into proper IP surveillance. It connects via PoE for single-cable simplicity, stores locally on MicroSD up to 256GB, integrates seamlessly with Dahua NVRs, and supports IVS tripwire and intrusion detection for meaningful event-based alerts. The 120dB WDR engine handles challenging contrast environments — backlit entrances, sunlit storefronts, and mixed-lighting corridors — without blowing out highlights or losing shadow detail. Compact, lightweight at just 0.48kg, fully metal-bodied, and available in both 2.8mm and 3.6mm lens options, this camera fits comfortably in virtually any standard installation scenario. If you need a dependable 4MP outdoor bullet camera that gets the job done without unnecessary complexity or cost, this is it.

The IPC-HFW2431SP-S tackles both extremes — Starlight technology keeps color detail visible down to 0.008 Lux in low light, while 120dB WDR balances high-contrast scenes so bright backlighting doesn’t wash out the person standing in front of it. Very few cameras at this price point offer both in a single device. Proven Reliability and Broad NVR Compatibility for Scalable Installations: One of the most underrated aspects of the Lite Series is how seamlessly it integrates with the broader Dahua ecosystem. This camera supports ONVIF Profile S/G/T and is compatible with Milestone and Genetec VMS platforms — making it ideal for installers who need reliable, future-proof equipment across a wide range of client projects. Whether you’re adding two cameras to an existing Dahua NVR system or building a fresh 16-channel setup from scratch, the IPC-HFW2431SP-S fits in without friction and performs consistently over the long haul. Ultra-Compact and Lightweight with Full Metal Build — Easy Installation, Built to Last: At just 0.48kg and 166mm in length, this is one of the most compact 4MP bullet cameras in the Dahua lineup, yet its full metal casing provides genuine durability. The IP67 rating with wide voltage tolerance (±30%) makes it resilient against Bangladesh’s unpredictable power supply fluctuations and monsoon weather. A single PoE cable powers and connects the camera, and the 360° pan / 90° tilt flexibility ensures you can achieve the exact coverage angle you need regardless of the mounting position. FAQ Q1: Is the Dahua IPC-HFW2431SP-S suitable for 24/7 outdoor use in Bangladesh’s climate? Yes, it’s well-suited for year-round outdoor deployment in Bangladesh’s climate. The IP67-rated full metal housing can withstand dust ingress and continuous heavy rain — it passes the 1-meter water submersion test for 30 minutes, meaning monsoon downpours are no issue whatsoever. The operating temperature range of –40°C to 60°C means even the hottest summer months in Bangladesh won’t affect performance. Additionally, the wide voltage tolerance (±30%) protects the camera against the power fluctuations that are common across many districts, reducing the risk of hardware damage during voltage spikes. Q2: What is the price of Dahua IPC-HFW2431SP-S in Bangladesh? The Dahua IPC-HFW2431SP-S is one of the most cost-effective 4MP IP cameras in the Dahua lineup, typically available in Bangladesh at a price range of BDT 3,500 to BDT 5,000 depending on the lens variant (2.8mm or 3.6mm), retailer, and whether it’s purchased as a standalone unit or as part of a bundle, with the best deals available through authorized Dahua distributors in Dhaka’s Elephant Road and trusted online CCTV platforms. Q3: Can the Dahua IPC-HFW2431SP-S record footage without an NVR using only a MicroSD card? Yes, the IPC-HFW2431SP-S supports standalone local recording directly to a MicroSD card of up to 256GB — no NVR required. You can configure continuous recording, schedule-based recording, or event-triggered recording (based on motion detection, tripwire, or intrusion alerts) through the camera’s web interface or the DMSS mobile app. This makes it a practical choice for small deployments where purchasing a full NVR is unnecessary, or as a backup recording layer in larger systems where NVR failure coverage is needed. For NAS-based storage, FTP and SFTP options are also supported. CCTV Camera Dahua DH-IPC-HFW2449M-S-B-PRO 4MP WizColor Fixed-focal Bullet WizSense Network Camera
