This is one of the new generation of hybrid system. So, rather than being just a traditional DVR, this is actually a NVR. You can even mix and match e.g. 4x normal CCTV cameras and 4x IP cameras. The interface is well done and the 720P HD is very sharp and detailed. It is a hybrid in the sense that it can take a combination of both analogue CCTV cameras and networking IP cameras.
