The DS-2CD2347G2-LU is a 4MP ColorVu fixed turret network camera designed for commercial locations that require full-color nighttime imaging, human and vehicle classification, built-in audio, and outdoor protection.
Its 2.8 mm fixed lens supports wide-area coverage, while the camera records video at up to 2688 × 1520 resolution. ColorVu technology and an F1.0 aperture help preserve useful color detail in low-light environments.
Human and vehicle classification helps focus supported motion and perimeter events on relevant targets. White light illumination provides full-color nighttime monitoring up to 30 meters, while 130 dB WDR helps maintain detail in high-contrast scenes.
The built-in microphone adds synchronized audio to compatible recordings. The camera also supports H.265+ compression, IEEE 802.3af PoE, ONVIF integration, and IP67 weather protection.
