What is the difference between a DVR and a NVR? Which is better?
A. Although somewhat transparent to the end user, NVRs represent a more open solution, utilizing standard computers and networks. DVS software can be hosted on any computer technology, can be easily upgraded, can scale both horizontally (adding servers) and vertically (upgrading servers), support multi-format cameras, and does not include costly proprietary maintenance fees. DVR’s are essentially computers, but the proprietary nature of them make them very costly and limited for any upgrades, scalability, and flexibility in configuration. Additionally, in the evolution of video surveillance, network video recorders represent where the technology is now and where it is headed. DVRs, although still very popular, represent a technology phase that has already been surpassed. Due to the extremely profitable aspect of DVRs – both in installation and in maintenance – they are still recommended by many vendors.
