I've got a couple of logitech 750e's. PoE, weatherproof, sound, good IR lighting, attractive. If you don't have a PC on, they record to an internal micro SD, which seems a bit of a bad idea (steal the camera, lose the recordings) but if you have the PC on then you have that copy too.

The downside is the awful logitech software. The iPhone app is ok, but the mac app is awful and the windows one only marginally better.

Note - don't buy the starter pack unless you want powerline ethernet/poe combined things. They sell a PoE version without all the other boxes.
