Oh get them from Vision consulting,they might try to tell you their NVR is better but it's not so don't buy that just the cams,I bought the 2MP SUPER STARLIGHT Cam and it's pretty impressive,full colour night vision.
Get a POE switch and get blue iris software on a decent PC,how many cams do you want to run?Alerts etc are much more powerful on blue iris,I'm testing out milestone also this week will let you know how it compares.
