What is the Difference Between an NVR and a DVR for a CCTV camera system?
A DVR stands for Digital Video Recorder, and an NVR stands for Network Video Recorder. Now, these two recorders fulfill pretty much the same purpose. They both receive video data from your security cameras, they let you manage all of your cameras in one place, view all of your live feeds, and of course, they record your security footage for you as well. While the purposes of these two types of recorders are essentially the same, their functionality is quite a bit different, so now we examine the main differences between a DVR and an NVR. Generally speaking, a DVR is the recorder that you would use for most analog security setups, whereas an NVR is what you will use for IP security setups. But the main difference between these two recorders boils down to this: how does the recorder receive the video? A DVR receives raw video input from the security cameras and it does all of the processing and encoding right there within the recorder, whereas an NVR is just receiving video streams from the network. So in other words, the IP camera does all of the video encoding and processing, it then streams that video to the network, and the NVR picks it up. hope this is all making sense to you so far, but if not don’t worry because we are about to dive a little bit deeper into each of these recorders. First, let’s take a look at this DVR. DVRs are used primarily in analog systems. a tribrid model can take various analog signals, such as TVI, CVI, and AHD. It can also take an IP input, which we will talk about a little bit later, at the back of this DVR, you can see that we have various connections
