Screening a visitor is a lot harder than screening a call. Even with a peephole, it's tough being inconspicuous when you're deciding whether or not to answer the door. It would be awesome to find out who's there without having to leave the couch. Apparently, we're not the only ones who feel this way.
DoorBot is a "smart" doorbell that connects to your phone via battery operated Wi-Fi video and alerts you when there's a visitor out front. That means you can see and converse with whoever's at your door without moving an inch — well, except to grab your phone.
You can use DoorBot even when you're not at home or for multiple properties, like vacation homes. It also has a partnership with Lockitron so you can let friends and family into your home when you aren't there.
