Connections

This sections explains how to connect the PC, cameras, and extension units. The types of cables and other hardware depend on how each setup
is done. Before starting installation work, check to make sure you have everything you need.
Connect the PC and the camera to the recorder using a HUB. The recorder is connected to the HUB via a LAN cable (straight). You can connect
the PC and camera using either 1 port or 2 port operation.
Using a HUB for Direct Connection
The PC connects to the camera using the Client PC port on the rear of the recorder.
Camera images input through the client PC port are sent to the PC from the same client PC port.

Use a LAN straight cable to connect the recorder and PCs via a hub.
