DVR stands for Digital Video Recorder. It is a device designed to record video in a digital format for storage, playback, and management. Unlike older VCRs that relied on tapes, DVRs use hard drives or other digital storage, making them more efficient and user-friendly.
While DVRs are a cornerstone of security systems, they’re also widely used for other purposes, such as recording live television. They convert analog signals into digital formats, ensuring high-quality video that’s easy to access and manage.
