IPC-HFW1431SP-S4 4MP WDR IR Mini-Bullet Camera

The IPC-HFW1431SP-S4 4MP WDR IR Mini-Bullet Camera is a reliable, high-performance surveillance solution designed to deliver superior image quality, durability, and advanced functionality for both residential and commercial security applications. Packed with cutting-edge imaging technologies, smart detection features, and robust build quality, this camera ensures dependable monitoring in diverse environments while maintaining cost-effectiveness.

Superior Imaging Performance

At its core, the IPC-HFW1431SP-S4 utilizes a 1/3” 4-megapixel progressive CMOS image sensor that produces sharp and highly detailed video with a maximum resolution of 2688 × 1520 pixels. The progressive scanning system minimizes distortion, ensuring smooth and clear capture of fast-moving objects. With an effective pixel count of 2688(H) × 1520(V), the camera delivers clarity that goes beyond standard Full HD, making it an excellent choice for environments requiring precise detail recognition, such as entrances, retail counters, or parking lots.

The camera’s minimum illumination of just 0.03 Lux @ F2.0 allows it to capture bright and usable images even in challenging low-light scenarios. When complete darkness sets in, its 18 built-in infrared LEDs provide effective night vision up to 30 meters (98 feet). Combined with Smart IR technology, the IPC-HFW1431SP-S4 automatically adjusts IR intensity to prevent overexposure on nearby objects while maintaining visibility across the entire scene.

Flexible Lens Options

The IPC-HFW1431SP-S4 comes with a fixed 2.8 mm lens (with an optional 3.6 mm version available) that provides wide-angle coverage suitable for monitoring open areas or specific target zones. At 2.8 mm, it offers a horizontal viewing angle of 93°, making it perfect for general surveillance of rooms, hallways, or outdoor premises. The 3.6 mm lens option narrows the view slightly to 81°, ideal for medium-range monitoring with improved subject detail.

The DORI distance model (Detect, Observe, Recognize, Identify) further enhances planning, offering detection up to 80 meters with the 3.6 mm lens, ensuring the camera adapts to various monitoring needs.

Advanced Video Features

The camera supports multiple video compression standards, including H.265, H.264, H.264B, and MJPEG, significantly reducing bandwidth and storage requirements without compromising quality. With dual streaming capability, users can enjoy flexible recording and remote viewing options.

Frame rates are optimized for smooth playback, offering up to 30fps at 2560 × 1440 resolution. Features such as 3D Digital Noise Reduction (3D DNR), Backlight Compensation (BLC), Highlight Compensation (HLC), and 120 dB Wide Dynamic Range (WDR) ensure clear images even in environments with strong lighting contrasts, such as entrances with direct sunlight or vehicle headlights at night.

Intelligent Security Functions

Equipped with smart video analytics, the IPC-HFW1431SP-S4 enhances proactive surveillance. Event triggers include motion detection, scene change, video tampering, illegal access, network disconnection, IP conflicts, and storage anomalies. These intelligent functions reduce false alarms and ensure operators are alerted only to genuine security concerns.

Additionally, its privacy masking feature allows the user to block up to four areas within the field of view, ensuring compliance with privacy regulations.

Connectivity and Integration

The camera supports multiple network protocols, including HTTP, RTSP, RTP, TCP, UDP, FTP, NTP, DHCP, DNS, IPv4/IPv6, and more, ensuring broad compatibility with third-party systems. With ONVIF support (Profile S/G), it integrates seamlessly with leading VMS platforms like Milestone and Genetec.

Remote access is simplified via Dahua’s Smart PSS, DSS, and DMSS applications, allowing users to monitor live feeds, playback recordings, and configure settings from PCs, iOS, or Android smartphones.

Durable Build for Harsh Environments

The IPC-HFW1431SP-S4 is built with a metal casing that offers durability and long-lasting performance. It carries an IP67 weatherproof rating, making it resistant to dust, heavy rain, and extreme outdoor conditions. The camera is designed to operate in a wide temperature range, from -40°C to +60°C (-40°F to +140°F), ensuring reliable performance in both freezing winters and hot summers.

Despite its rugged construction, the camera maintains a compact and lightweight profile, measuring just 164.6 mm × Φ70 mm (6.6″ × Φ2.8″) and weighing only 0.4 kg (0.9 lb), which makes it easy to install discreetly in various environments.

Power Options and Efficiency

For flexibility during installation, the IPC-HFW1431SP-S4 supports both 12V DC and PoE (IEEE 802.3af), allowing users to choose the most suitable power method. With a low power consumption of under 6.0W, it remains energy-efficient while delivering consistent surveillance.

Applications

The IPC-HFW1431SP-S4 is versatile enough for multiple applications, including:

• Retail stores – Monitor entrances, checkout counters, and aisles.
• Residential properties – Secure driveways, gates, and building perimeters.
• Office spaces – Ensure safety in lobbies, corridors, and server rooms.
• Warehouses and factories – Maintain oversight of storage areas and production lines.
• Public facilities – Ideal for schools, hospitals, and transportation hubs.

Conclusion

The IPC-HFW1431SP-S4 4MP WDR IR Mini-Bullet Camera is a cost-effective yet feature-rich surveillance solution that combines superior imaging, intelligent security functions, and durable construction. Whether deployed indoors or outdoors, it provides peace of mind with reliable 24/7 monitoring, efficient storage management, and easy integration with existing security systems.

With its balance of performance, resilience, and affordability, this mini-bullet camera is the perfect choice for users seeking professional-grade security without compromise.
