If you’re considering setting up a home security system, you may be wondering which type of recorder is right for you. DVRs and NVRs are both digital video recorders that can be used to store footage from security cameras, but they work in different ways. Here’s a look at the key differences between DVRs and NVRs to help you decide which one is right for your needs.
DVRs are stand-alone units that connect directly to security cameras. They encode and decode video signals from the cameras and store footage on a hard drive. NVRs also connect to security cameras, but they don’t have an onboard encoder. Instead, they rely on the cameras to do the encoding, which means that they can work with IP cameras that use a variety of compression formats.
NVRs are typically more expensive than DVRs, but they offer some advantages in terms of flexibility and expandability. For example, because NVRs don’t have an onboard encoder, they can usually accommodate more cameras than DVRs. And because they use IP cameras, you can easily add new cameras to an existing NVR system without having to replace the recorder.
Frequently Asked Question
Which is cheaper DVR or NVR?
As discussed before, the DVR system uses analog cameras. The camera is responsible for streaming an analog single to the recorder, which then processes the video data. Unlike NVRs, most DVR cameras are less expensive. 
NVR systems are more expensive than DVR systems, but they offer a number of advantages that make them worth the extra cost. NVR systems are easier to install and maintain, and they offer better performance and scalability. If you need a high-performance surveillance system, NVR is the way to go.
