Do you use a QNAP NAS as a monitoring center? Then it is certainly useful to use modern hardware for multiple IP cameras. If you already have a QVR Pro Gold license, just purchase this QVR Pro extension and use it on your QNAP NAS with a compatible system (QTS 4.3.4.0483+). With the QNAP LIC-SW-QVRPRO-8CH-EI, you get 8 monitoring channels that you can remotely view and, of course, upload to storage.
