Is it important for us to set a wifi camera in our house?

I'd say yes. Especially if you lived in a crowded community. We live in a less crowded community but there has been break ins recently which is unfortunate. That's when we decided to get one, to at least, scare the intruders off. We got ourselves the one with 2 way communication. haha. To maybe give them a heads up that they are being watched already just before they touch our door knobs! #ScaringOffIsReal
