If you only need a NAS for surveillance, then the QVR Pro Appliance is the perfect choice for your workplace or home. In a conventional NAS-based surveillance system, surveillance is just one of the many running applications on the NAS and there is no dedicated storage for surveillance recordings. The QVR Pro Appliance overcomes these storage and performance issues by providing dedicated storage space and reserving full system resources for surveillance, delivering the utmost performance to fulfill professional surveillance system requirements. The QVR Pro Appliance comes with built-in camera channel licenses and essential applications to enable local installation without requiring an Internet connection.
