- Video Capture: IP cameras capture high-definition video footage. These cameras typically compress the video data themselves (using codecs like H.264 or H.265) before transmission.
- Network Transmission: The compressed video data is sent from the IP cameras to the IP NVR over your network (Ethernet cables or Wi-Fi). Many IP NVRs feature built-in PoE (Power over Ethernet) ports, meaning a single Ethernet cable can provide both power and data to the camera, simplifying installation significantly.
- Recording and Storage: The NVR receives the digital video streams and records them onto its internal hard drive(s) for later review. It manages file compression, storage allocation, and potentially redundant backups.
- Viewing and Management: Users can view live footage or playback recorded video directly from the NVR (connected to a monitor) or remotely via a computer, smartphone, or tablet using dedicated software or a web browser. The NVR also allows for system configuration, motion detection setup, and other advanced features.
This network-centric approach provides immense flexibility, allowing cameras to be located far from the recorder, as long as they are on the same network.
