The Dahua IPC-HFW2441S-S is a 4MP IR fixed-focal bullet WizSense network camera built for users who want dependable, AI-powered surveillance without the premium pricing of full-color models. Using a 1/2.9″ CMOS sensor, it delivers low-noise, high-definition footage suited for entrances, driveways, and general-purpose outdoor and indoor monitoring.
Resolution and frame rate offer solid flexibility. The Dahua IPC-HFW2441S-S outputs a maximum of 2688 x 1520 at up to 20fps, or 2560 x 1440 at up to 25/30fps, letting users balance maximum detail against smoother motion depending on the scene. Video is encoded through H.265, delivering a high compression rate and ultra-low bit rate that keeps storage and bandwidth use efficient.
Night vision is handled through a built-in IR LED, reaching a maximum illumination distance of 30 meters, giving reliable coverage after dark. ROI and Smart H.264+/H.265+ add flexible coding that adapts to a range of bandwidth and storage environments, while rotation mode, WDR, 3D noise reduction, HLC, and BLC help maintain image clarity across varied lighting conditions, including strong backlighting.
Smart detection is powered by deep learning. The camera supports intelligent monitoring through intrusion and tripwire detection, both with accurate classification of humans and vehicles to reduce false alerts from irrelevant motion. SMD Plus adds a further layer of motion filtering, helping the camera focus only on activity that genuinely matters.
Digital watermarking is built in as well, supporting footage authenticity for situations where verified recordings matter. A built-in microphone captures real-time audio alongside video, adding useful context to recorded events.
Storage flexibility is a strength here, with support for microSD cards up to 256GB, giving users a straightforward local storage option without requiring a subscription. Power flexibility is also built in, supporting both 12VDC and PoE, simplifying installation across different setups.
Built for demanding outdoor use, the Dahua IPC-HFW2441S-S carries an IP67 rating, standing up to dust, rain, and harsh weather conditions. Its solid construction and dependable core feature set make it a strong fit for users who want a capable, AI-enabled camera that covers the essentials without unnecessary extras — a practical choice for homes, small offices, and general-purpose security deployments.
