hi guys i have now 4 GE cheap cameras i buy them at the local pricesmart, the cameras came with rca connectors, they are connected to a tv with a 4 RCA video channel selector this is a very low budget system, i know this is a toy for you guys, but it have helped in my store with shoplifting... now the problem is that i have to change manually wich camera i want to see, so i would like to have a quad so i can see the 4 cameras on my tv... does quads work with this kind of cameras?? links with quad that would work for me???

ok im thinking in buying this one : http://lorexstore.strategicvista.com/product.aspx?id=779&nav=2 this one has bnc inputs and outputs, my cameras have rca plugs and my tv rca jacks would everything work ok if i just put the rca to bnc adapters??? i dont want to buy it to see that it doesnt work with cameras... my cameras are cheap GE cameras that cost me around $50 dollars in the local pricesmart

thanks another question i saw a really cheap 8 camera quad on ebay, but someone toll me that i shouldnt buy it because it is refurbished... its true??
