Cameras do not have to be physically connected to the recorder, nor is there a need for power splitters. As long as the cameras and recorder share the same network, the system can record and save files. As such, NVR drives are used with IP cameras that have internet connectivity. Because data is being transferred from the security camera to the storage drive, the security cameras must be connected to the Internet. NVR systems encode and process the video data from the camera, then stream it to the NVR, which is used for storage and remote viewing. This is more efficient than a traditional video recording. Each camera comes equipped with a processing chip that streams the video to the NVR system for storage. Digital Internet protocol (IP) cameras process video.No power splitters or wall sockets are required.

NVR cameras store video footage on one or multiple digital storage devices, such as hard drives, solid-state drives, and flash drives. NVR records video data to a server and is commonly used in commercial security.

Let’s look at the differences between DVR and NVR and break down the capabilities and features you can expect. They perform the same function-recording security camera footage and allowing you to play it back-but differ in how they do it and what cameras can be connected.

When shopping for a business security camera system, you might have the option to choose a digital video recorder (DVR) or network video recorder (NVR), both of which record and store video files.
