Powered by dual-core Intel Atom CPU and 1GB memory, the VS-6020 Pro VioStor NVR is the high performance network surveillance system for monitoring, video recording and playback from multiple IP cameras. The Linux-based system supports PC-less quick configuration, monitoring of IP cameras over the network, and video playback by connecting a monitor to the built-in VGA connector, a USB keyboard, and a USB mouse. The VioStor NVR supports simultaneous megapixel recording (up to 8-megapixel) and unique multi-server monitoring, a feature which allows monitoring of up to 120 IP cameras from multiple QNAP NVR servers at the same time. No extra software is required on the PC. In order to enhance system security, the NVR provides advanced event management feature for the administrator to define more handling options when different events or alarms are triggered.
