Its sturdy housing, widely listed metal-body construction, and IP67 weather resistance help it handle dust, rain, and everyday outdoor conditions. The design also supports flexible angle adjustment for easier installation and coverage optimization.4MP High-Resolution SurveillanceThe 4MP image sensor helps this Dahua network camera deliver sharp and detailed footage for day-to-day monitoring. With a maximum resolution of 2688 × 1520, it captures clearer facial details, movement, and scene information than lower-resolution alternatives. This makes it suitable for entrances, receptions, shops, hallways, and perimeter surveillance where image clarity matters.Fixed-focal Lens for Stable CoverageDahua IPC-HDW2431TP-AS is commonly listed with a 2.8mm fixed lens, while some related variants are also available in 3.6mm options. The fixed-focal design keeps setup simple and reliable, which is ideal for users who want a straightforward installation. It delivers a practical field of view for covering lobbies, counters, corridors, and room entrances effectively.Built-in Microphone SupportA major advantage of this model is its built-in microphone, which allows audio capture alongside video recording. This can be useful in retail counters, offices, receptions, and other monitored spaces where sound helps provide better context during incident review. It reduces the need for an additional external microphone in many standard surveillance setups.Infrared Night Vision PerformanceThe camera includes infrared LEDs with up to 30 meters of IR distance, allowing it to monitor areas even in low-light and nighttime conditions. This helps maintain visibility around building entrances, parking areas, corridors, and exterior walls after dark. Automatic or manual IR control also helps improve performance depending on the installation environment.Smart Video Compression EfficiencyThis Dahua IP camera supports H.265 and H.264 compression technologies to help reduce bandwidth usage and storage requirements. That means users can store longer footage and stream more efficiently without sacrificing too much image quality. It is especially beneficial for NVR systems and business environments where multiple cameras are installed at once.Low-Light Image CapabilityThanks to its low illumination performance, the camera can produce usable images in dim environments before infrared fully takes over. This helps maintain better scene visibility in transitional lighting conditions such as evening entryways, shaded outdoor spaces, or weakly lit warehouses. It is a practical feature for around-the-clock surveillance requirements in real-world conditions.IP67 Weather-Resistant ProtectionDahua designed this series with IP67 protection to support dependable outdoor use in dusty or wet environments. This makes the camera suitable for gates, garages, side walls, loading areas, and building exteriors. Users in Bangladesh can also benefit from this weather-resistant build during seasonal rain and humidity, especially in uncovered installation points.PoE for Easier InstallationPower over Ethernet support simplifies installation by allowing both data and power through a single network cable. This reduces wiring complexity, saves time during deployment, and keeps setups cleaner. It is particularly useful in offices, shops, apartment buildings, and commercial projects where organized cable management and reliable connectivity are important.MicroSD Card Storage FlexibilityThe Dahua IPC-HDW2431TP-AS supports onboard microSD card storage, giving users another recording option beyond an NVR. This is useful for backup recording, standalone deployment, or small setups where a full recorder may not be required initially. It adds flexibility for home users, branch offices, and small business owners who want simpler surveillance expansion.Flexible Mounting and Angle AdjustmentThis dome camera supports wide pan, tilt, and rotation adjustment, helping installers fine-tune the viewing angle during setup. That flexibility makes it easier to align the scene properly and reduce blind spots. It is particularly useful when mounting on ceilings or walls in compact spaces where accurate positioning is essential for dependable surveillance results.Suitable for Home and Business SecurityThis model fits a wide range of surveillance needs, from small residential setups to larger commercial environments. It can be used in homes, office reception areas, retail stores, hallways, warehouses, and entrances. The mix of 4MP clarity, audio support, night vision, and durable construction makes it a practical all-purpose security camera for everyday monitoring.Reliable Dahua Network PerformanceAs part of Dahua’s network camera lineup, this model is built for integration with modern IP surveillance systems.
