Review on 📷 Swann 4 Camera 8 Channels POE NVR Master 4K Upscale Video Wired Surveillance System for Indoor and Outdoor with Night Vision, Heat Motion Detection - SWNVK-876804 by Jeff Westra

They don't look like an IP camera or NVR. In case something has changed and I don't know, IP cameras use 3 pairs, tx, rx and POE (orange pair, green pair and brown pair). The cable that comes with it only has 2 pairs, which leads me to believe it's an analog camera, using one pair for video and one for power. NVR also means Network Video Recorder, but you cannot connect the IP camera to a hub/router, they must be connected directly to the rear ports.
