NVRs work by receiving video streams from IP cameras via a network connection. These cameras digitally process the video before sending it to the NVR, which then stores the footage on a hard drive or cloud storage.
Key components of an NVR system include:
- IP Cameras: Capture and transmit video digitally.
- Ethernet Cables (PoE): Provide both power and data transmission.
- NVR Device: Stores and manages recorded footage.
- Hard Drive (HDD): Stores recordings for playback and review.
