<p>The GV‐BX4700 is a series of indoor IP cameras containing a varifocal and a fixed focal model. GV‐BX4700 can support H.265 video codec to achieve better compression ratio while maintaining high picture quality at reduced network bandwidths. The camera is equipped with a Super Low Lux CMOS image sensor which allows the camera to provide a color live view in near darkness. The camera features a mini USB port which supports wireless connection through a GV‐WiFi Adapter (optional) or external storage using a USB hard drive.</p>
