QNAP's VioStor network video recorder (NVR) series is among the first video management software (VMS) platforms to support the VIVOTEK FE8172/72V 5-Megapixel and FE8171V 3-Megapixel fisheye fixed dome network camera. The VioStor NVR allows users to digitally zoom into areas of a hemispheric image in both live or playback view. Users can also view a complete scene unfold without obstruction while simultaneously displaying multiple independent dewarped views from a VIVOTEK FE8172/72V/71V camera.
This article will guide you to configure the VioStor NVR to record the videos from the VIVOTEK FE8172/72V/71V network camera and dewarp the fisheye images for live monitoring.
