NVR systems can record and store footage locally through an SD card, a good storage option for those who do not want to pay extra.

The good news: cloud storage is not your only option. Cloud storage capacity is limited, too, so if you need more storage, expect to pay a premium. However, some security providers charge an additional fee for cloud storage. Saving footage to the cloud makes for quick access-you can log in from anywhere to watch the footage.

Coaxial cable is typically larger and takes longer to install than a single Ethernet cable.One coaxial cable and one power cable per camera required.

Cameras must be connected to the recorder via a coaxial cable-one limitation of coaxial connections is that they do not provide power, so an additional connection for power is needed. In a DVR system, the analog cameras stream an analog signal to the recorder, which then processes the images.

The cameras used by a DVR system must be analog, which is not connected to the Internet. DVR has long been useful in recording and storing video, but it lacks some key capabilities compared to NVR.ĭVRs require the use of power splitters and wall sockets. NVR is a newer technology that provides enhanced video recording capabilities and more features, such as audio recording, compared to more traditional DVR systems. 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. A single Ethernet cable that provides power, video, and audio.However, for businesses with more complex security concerns, NVR drives can be stored off-site as an extra measure to prevent an intruder from gaining access to the server. 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.
