Welcome. It's not exactly plug and play, but I've got it down now where I can set up cameras to be fully operational in less than 30 seconds. Once you download the right tools, such as SADP, it's really not that difficult.
Thanks for the link. I've managed to set the nvr up properly, done a connection test and alls good. I'll probably get the cameras in a few days. Hoping that'll go smoothly. The dome cameras take sd card also, and I was wondering what the advantage is having an sd card inside them as well? The cameras are DS-2CD2142FWD.
