The pitch: Sometimes you can't hear the doorbell and sometimes the person at the door isn't someone you want to see. DoorBot sends video and ringtones right to your phone so you can quickly open the door for your mom and avoid that annoying neighbor.
The goods: Attach a weatherproof and secure DoorBot unit just off your door, connect it to your WiFi network, and wait for someone to ring. Your phone will notify you and provide live video and a two-way audio connection. Yes, that means you can actually catch the UPS delivery person and tell them where to leave the package. Along with weatherproof housing and multiple phone-ring capabilities, the DoorBot comes with a strong antitheft guarantee: If your DoorBot gets lifted, it is replaced for free.
The result: Because it was funded on the patent and vetting-focused Christie Street crowdfunding platform, which holds unspecified funds in escrow until inventors prove they're making progress, it's hard to tell exactly what DoorBot pulled in, but it's available now at the DoorBot site.
