anyone have some suggestions for a home security system? Not sure hoe extensive I want to go. Was thinking just a camera that covers the front entryway, maybe another to have all doors covered. But considering something to maybe tell me if a door is opened and things like that too. Just wondering what you guys have used and what I go anyone can provide. My main hope would be to have a camera that would send an alert and either a pic of video to my iPhone if someone enters.
