I have been watching and getting opinions on Hikvision & Dahua for front and back and now have a another question. I have a small (about 4 feet square) front porch with the dreaded Foscam ptz w/4mm lens. I'm sure a 2.8mm will work a lot better here. Would a 1.3mp work ok in this situation? I've heard 1.3 seems better at night than 3mp. Is a 4mp overkill? Being at the front door I think sound would be nice (I have that with the Foscam). I don't really need ptz, I've looked at the mini domes, you have other suggestions? I value your opinions.
