CCTV DVR (Digital Video Recorder) and NVR (Network Video Recorder) are essential components in video surveillance systems, responsible for recording, storing, and managing video footage from CCTV cameras.
- DVR (Digital Video Recorder): Primarily used with analog cameras, DVRs convert video signals into digital format for storage. They often include features such as motion detection, scheduling, and remote access via the internet. DVRs typically connect to cameras via coaxial cables.
- NVR (Network Video Recorder): Designed for IP cameras, NVRs record video data transmitted over a network. They allow for higher resolution recordings and more advanced features, such as remote monitoring and cloud storage capabilities. NVRs generally offer greater flexibility in camera placement, as they rely on Ethernet cables or Wi-Fi.
Both DVRs and NVRs are crucial for effective video surveillance, enabling users to review footage, manage camera settings, and enhance security measures in various environments.
