We’ve seen a lot of compact ones that are small enough to be placed on shelves and tables, and can even be enclosed inside a stuffed toy. However, there’s a new breed of home security solution that’s currently gaining the spotlight – one that’s being put front and center, right at your front door. Door monitoring cameras allow you to get a good view of your entryway no matter where you are. This type of security camera works almost like a doorbell, except that when someone’s at the door and pushes the button, you’ll get an alert from your smartphone and have the ability to answer the door remotely. It’s a great way for when you’re expecting a guest or a friend. What’s more, it also lets you see who’s stopped by in your place when you’re away from home, and whether or not the person at the door is welcome to see you.
