DAHUA IPC-HDW21249T-S-IL-0280B-S2 4MP Smart Dual Light WizSense Fixed-focal Eyeball IP Camera with Built-in Mic, 2.8mm Lens, IP67, IK10, PoE

For a business owner monitoring a small parking lot after hours, the DAHUA IPC-HDW21249T-S-IL-0280B-S2 delivers sharp 4MP video with smart motion detection and dual-light illumination, ensuring clear footage even in complete darkness. This eyeball-style IP camera combines a 1/3" 4MP progressive CMOS sensor with a fixed 2.8mm lens (98° horizontal field of view) to capture detailed images up to 2688 x 1520 pixels at 20 fps. Its Smart Dual Light technology automatically switches between IR (up to 30m) and white light to deter intruders and capture colour details when motion is detected. Built-in WizSense AI algorithms (SMD Plus and Perimeter Protection) reduce false alarms by distinguishing humans and vehicles from other moving objects. The camera is housed in a rugged IK10-rated metal casing with IP67 weatherproofing, making it suitable for outdoor use in temperatures from -30°C to 60°C. It supports H.265 compression for efficient storage, has a built-in microphone for audio recording, and offers flexible power options via 12V DC or PoE (802.3af).
