Which device records analog CCTV signals in a standalone unit?

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

Answer: (B)

The main idea here is selecting a device that directly handles analog CCTV inputs and stores the footage in a standalone box. A DVR is built to receive analog camera signals (usually via coax/BNC), digitize and compress them, and store the video on an internal hard drive within a self-contained unit. This makes it the standard choice for standalone recording of analog CCTV. NVRs are designed for IP cameras that stream over a network, so they’re not the typical fit for analog signals unless adapters are used. VCRs are consumer tape recorders and aren’t practical for modern security systems with multiple cameras and features like playback search or remote access. LANs are just networks, not recording devices.
