Question for connecting ruckus switch or ISP gateway with ethernet devices

[jessesurf]

Hello, I have a Lennar home which came with Ruckus ICX-7150 switch and 2 R320 access points.  I have ATT internet with an ISP gateway (WIFI disabled only providing connectivity to the ruckus switch).

My question is: I have security camera system which requires direct ethernet connection, but same question for any device requiring direct ethernet connectivity.  Is it recommended to connect the ethernet device to the ISP gateway or to the Ruckus switch (one of the Slot 1 ports which are also connected with the access points)?  I've tested both and either way seems to work, but are there performance or compatibility issues in either case?
