Anybody know anything about DVR's? I need one for some cameras at work...I don't really know much, I saw one on ebay that looked ok. Would be nice if it was motion sensing. But I really know nothing about them....

honestly would avoid ebay.     " works on day and night and it will do automatically "    , im not crappin on this dvr, or any of them, however, ive installed many of them, and if i can pick out many grammatical errors, ill go to a place where i can either see the unit in person and ask questions, find a client and ask questions, im not seein quality here tho, cheap price yes, but...., you might end up having to re-do an install.
