Thanks all for the info
tomcctv - I have only purchased one foscam, as a trial so I am not stuck on that camera - I will have ethernet connectivity to each camera so do not really need to connect via wifi - if I go with IP MP cameras which one do you recommend - by only using 2 -3 cameras could I reduce by required bandwidth enough to not require a pc at the gates and only use a switch/ router and the uverse gateway.
ssmith - thanks for the info on enclosures
My thinking is that the switch/ router and Uverse gateway will not require an air conditioned enclosure (this could be a misconception) - however I quite sure that as soon as I put a PC/ DVR outside I will require AC.
Thanks all for your help so far
