Home (Outdoor) Network Security Camera Recommendations?

I'm looking for a network security camera that I can put on the front porch (out of the rain/snow, but not out of the cold!). It needs to meet the following critera: 1) Can take HIGH RES pictures - I need to be able to actually SEE who was there, and identify them in court, for example. 2) It must be able to take pictures when it senses motion. 3) As there is lighting on the porch, night vision isn't required, but a low-light feature might be helpful. 4) It needs to store the pics centrally on a local server via ethernet, it case someone tries to damage it. Lastly 5) It has to be "home affordable" - I've found this camera for $3000, now I need a home version.

I've looked everywhere, and all recommendations had horrbile reviews. 3 out of 5 stars at best. HELP ME OUT!!!
