PoE security cameras use Ethernet for data and power when connected to compatible equipment. Plan wired CCTV around cable routes at home, in a shop or in a warehouse, then compare viewing angles, night vision, zoom and NVR recording.
Pairing PoE cameras, power and recorders
Check whether each camera needs PoE or PoE+, then verify both the per-port and total switch power budget.
Match recorder channels, supported resolution, incoming bandwidth and hardware version to the cameras.
An Ethernet port does not prove cross-brand compatibility. Check recording, audio, detection and playback functions individually.
Check the product contents for an included hard drive, cameras and required cables. Retention depends on bitrate, camera count and recording mode. Set the period you need to keep, then calculate storage instead of choosing an NVR by drive size alone.
