VH331-A2 series 2MP Starlight WDR IR Face Capture IP PTZ Dome Camera provides high quality video with the resolution up to 1920x1080@30fps, adopts H.265/H.264/M-JPEG compression formats, and boasts of excellent resolution and Color reproduction ability to ensure richer and more accurate details to be acquired and also guarantee the accuracy of intelligent analysis in a more effective way.

This product adopts large power LED infrared lamps, of 850nm infrared wave length, long night vision distance up to 200m and strong illumination. SMART IR technology is adopted to automatically adjust the output power of the IR LED as per the lighting conditions, so as to ensure ideal night vision effect.

User-friendly GUI interface design allows users to perform dome PTZ control easily via network and to configure detailed camera parameter settings. At Web interface, users can perform dome camera settings and operations by using a mouse which is more convenient than the traditional keyboard control. It also supports area zoom and image PTZ function.

VH331-A2 series PTZ dome cameras also feature general dome functions such as preset, pattern, autopan, autoscan, timed tour and normal tour.
