Hikvision DS-2FP4021-B is an ultra-compact microphone that gives you HD wideband audio pickup in all directions out to 33 feet. Made from durable aluminum, the ECM microphone array with embedded DSP audio processor offers superior audio quality. The adaptive active noise cancellation algorithm improves sound — and greatly reduces background distractions. The microphone only measures 2.5-inch in diameter — place it anywhere.
