Alright, BS world. I am, by no means, a dumb guy or an idiot or anything (in my opinion!)... But, I'm not super technologically advanced. I want to install an inexpensive "nothing too fancy" type of security camera to view my front door. Something that maybe I can view live from my iPhone perhaps? Looking for something that is a fairly simple DIY setup. When looking online and on Amazon, there seems to be many different types, which I know nothing about. Any advice or suggestions would be greatly appreciated. And again, I'm not looking for any crazy high end security system that will cost me hundreds of dollars. I live in a very safe area and just want something that can monitor the outside of my place. Mainly see who walks up to my door, that sort of thing. Thanks in advance.
