A DVR, or Digital Video Recorder, is a device that records video digitally onto a storage medium like a hard drive, SD card, or USB flash drive. In consumer electronics, it allows users to record TV programs, pause live TV, and store shows for on-demand playback. For security systems, DVRs convert analog camera feeds into digital data for storage, transmission, and remote viewing.

Consumer electronics

Function: A DVR in a cable or satellite set-top box allows you to record, store, and watch TV programs digitally.

Features: It can record programs while simultaneously playing back a different one, pause live television, and schedule recordings from a program guide.

Storage: Storage is local, often using a hard disk drive (HDD) or solid-state drive (SSD) inside the box.

Cloud DVRs: Some modern services use "cloud DVR" to record and store video on a remote server instead of a local device.

Security and surveillance

Function: A DVR receives raw video from analog security cameras, processes and digitizes the video, and stores it.

Storage: Footage is stored on an internal hard drive.

Connectivity: Analog cameras are connected via coaxial cables to the DVR unit.

Access: The footage can be accessed by connecting a monitor to the DVR, viewing it over a local network, or through remote access via the internet.

Usage: DVRs are a key component in many security systems, providing local, on-site storage for surveillance footage.
