I use Hikvision 2032s and a few cheap Dlink and Trendnet cameras, and use Blue Iris software.
Out of all of them, the Hikvisions are the most reliable.
http://www.nellyssecurity.com/camera...2cd2032-i.html You didn't mention if you need audio as well, the 2032 doesn't do audio but other models. do.
You can get them cheaper direct from China, as low as $95.00 but shipping takes a while, and support is less than stellar.
A good resource for IP cameras is the forums at cam-it.org
