Terminology Tuesday: DVR, Hybrid DVR & NVR


It’s time for another Terminology Tuesday and the topic du jour is on recording. I’m often asked about the difference between DVR, NVR and Hybrid DVR. Let’s start out with some basic definitions:
DVR = Digital Video Recorder, these recording devices capture video from analog cameras
NVR = Network Video Recorder, these devices are used in IP surveillance systems
Hybrid DVR = Has both analog inputs and the capabilities for IP video surveillance of an NVR

Although many would say that the DVR is “old technology”, it still has a place in today’s world, albeit limited. For a cost-effective solution today, the hybrid should be considered. This allows for “phasing-out” of analog cameras as they fail or as the system grows. In this scenario all new additions can be upgraded to IP network cameras, with no additional cost to switch from DVR to NVR. NVRs should be used for all new facility installs. Today’s NVRs are feature rich and allow off-site retrieval of live videos as well as recorded, since input is direct from the network.

Have an idea for a “Terminology Tuesday” post – let me know in the comments below:

    Your definition of a DVR is referring only to analog camera’s. Isn’t it quite possible that IP cameras may be connected to a DVR and not connected to a network (or stored on a NVR)? Just for clarity.

      Hello WAB – great question, but actually you can not connect an IP camera to a regular DVR, as it will not be able to communicate and transfer data, IP cameras must be connected to a network to function.

      Both analog and IP cameras will work on the Hybrid DVRs, and therefore these are a great solution.
