I have multiple 5231r-ze cameras on my home at the current time. In reading about all of the new 4mp cameras, I am looking to upgrade for a better image both during the day, and at night. I believe varifocal would be best, but could be persuaded to a fixed lens. I am looking for some recommendations for any that have actually replaced their 5231's and what cameras you prefer and what you compared. (Sorry if this has been asked, just wanting more opinions).
