Which device can be attached to a network so file storage can be a separate device on the network?

• A. NVRs
• B. DVRs
• C. VCRs
• D. WANs

Answer: (A)

To store files on a separate device across a network, you need a device that handles IP video streams and writes to network storage. A network video recorder does that: it accepts video from IP cameras over the network and saves it to storage that can live on another device on the same network, like a NAS or storage server. This separation of capture and storage is what makes the networked approach flexible and scalable. By contrast, a DVR handles analog cameras and stores footage on its own internal hard drive, with limited or no reliance on networked storage. A VCR records analog tape, not suited to network storage. A WAN is a network, not a recording device, so it isn’t the component you attach for storage.
