A DVR (Digital Video Recorder) works by capturing analog video signals from connected security cameras, converting them into digital format, and storing the footage on an internal hard drive. It typically connects to cameras via coaxial cables, receiving video feeds continuously or based on set schedules. The DVR then allows users to access and manage recordings through its user interface, enabling functions like playback, searching, and exporting footage. Many DVRs also support remote access, so users can view live or recorded footage via mobile or desktop applications over an internet connection.
