The latest technology in security; NVRs make use of high speed network communication to transfer huge, high-speed, high-quality recordings from megapixel cameras. They offer the entire scope of features from our DVRs. However, when you are recording at up to 128 times the picture size, there is no comparison in detail. The wave of the future is definitely IP network camera systems. Unlike computer based solutions, our NVRs are not susceptible to viruses, hackers, external update failures, driver conflicts, or any of the other issues that computers have.
