Connect IP cameras to the PC Prerequisite You have followed the entire procedure in Ethernet card setup Procedure The procedure applies to a Cisco  SG 100D 8 port Gigabit PoE-switch, which is supported with MediaRecorder. Using cross-network cables (cat-5e or newer), connect the Ethernet card on the PC to one of the four right ports of the PoE-switch. Connect the camera to one of the four left ports of the PoE-switch. Do not use any of the four right ports for this purpose, since they do not supply your cameras with power. Power up the PoE-switch. Notes The Power over Ethernet (PoE) switch is a device that receives and sends data (in this case, video data from the camera) and passes power along on twisted-pair Ethernet cabling. If you use multiple IP cameras, connect them to separate ports on the PoE-switch. Make sure the capacity of the switch is high enough for the cameras. See  Power over Ethernet in Recording devices
