Further details
✔ 12 Megapixel resolution
The Dahua IPC-HDW21249T-S-IL S2 integrates a 12MP CMOS sensor with a maximum resolution of 4480 × 2512 pixels at 15 fps . It also supports 5MP resolution at 25/30 fps, allowing you to choose between higher definition and greater image fluidity.
✔ 2.8mm wide-angle fixed lens
The 2.8mm fixed lens with F1.6 aperture offers a 112° horizontal, 58° vertical, and 136° diagonal field of view. It is suitable for monitoring entrances, courtyards, gardens, shops, offices, and other areas requiring wide visual coverage.
✔ AI-ISP Technology
AI-ISP technology uses intelligent image processing to adapt to scene conditions and enhance detail rendition. The minimum declared sensitivity is 0.008 lux in color and 0.0008 lux in black and white , with an F1.6 aperture and a 30 IRE reference.
✔ WizSense Artificial Intelligence
Dahua WizSense technology uses deep learning algorithms to distinguish people and vehicles in supported intelligent functions. This allows for more selective event detection and improved alarm management.
✔ IVS perimeter protection
The camera supports intelligent Intrusion and Tripwire functions. These allow you to detect intrusions in defined areas and crossing virtual lines, classifying the subjects as people or vehicles.
✔ SMD Plus
Smart Motion Detection Plus technology analyzes motion events and classifies relevant subjects, helping filter out alarms generated by irrelevant elements. It's especially useful in outdoor environments subject to frequent motion.
✔ Smart Dual Light
Smart Dual Light technology combines infrared illumination and warm white light. During nighttime monitoring, the camera can use infrared; when a target is detected in the monitored area, the white light can be activated to capture color images.
In the version with 2.8 mm optics , the declared range is 30 metres for infrared and 20 metres for white light .
✔ Super AI Coding H.265/H.264
The S2 version integrates Super AI Coding technology, which uses intelligent object and scene recognition to optimize video coding. This technology helps improve compression efficiency and reduce bandwidth and storage requirements. Smart H.265+ and Smart H.264+ technologies are also supported.
✔ Three video streams
The Dahua IPC-HDW21249T-S-IL S2 supports 3 video streams . The main stream can reach 12MP at 15fps, the second stream supports resolutions up to 704×576, while the third stream reaches 352×288 at 1fps in PAL systems. The available frame rates depend on the overall encoding capacity.
✔ Audio with built-in microphone
The built-in microphone allows for ambient audio capture. G.711a, G.711Mu, PCM, and G.726 formats are supported. Use of audio recording must comply with applicable regulations.
✔ Network Camera, PoE and microSD
The camera has a 10/100 Mbps RJ45 Ethernet port and supports ONVIF Profile S, G, and T , as well as RTSP and major network protocols. It can be powered via IEEE 802.3af PoE or 12 VDC.
The microSD slot supports cards up to 256 GB . FTP, SFTP, and NAS storage modes are also available. Management is supported via Smart PSS Lite, DSS, and DMSS.
✔ IP67 protection
The IP67 rating makes the camera dustproof and waterproof under the conditions specified in the certification. The declared operating temperature ranges from -40°C to +60°C .
