Last Revision Date: 7/21/2015
This article describes how to connect more than two cameras to a two-port bus card.
Use a multi-port hub to connect more than two cameras to the same card. You can purchase multi-port hubs that will allow you to put more devices on the same bus. If camera performance becomes inconsistent as you continue to add more cameras, it may be the result of a lack of power. Ensure adequate power is reaching each camera.
