We haven't seen the smart lock since June, and in that time Goji's been getting busy. It's added three new features to the "electronic deadbolt": a proximity sensor, accelerometer and Zigbee, which allows you to manage your front- or back-door access while you're away from home. As a refresher, Goji allows you to send out an unlimited number of virtual keys restricted by time and date, giving the holders wireless access to your home via Bluetooth or WiFi. Should a knocker come twist your knob, the 1-megapixel camera will snap their portrait and alert you to their presence, allowing you final say in who gets to come in. The Android- and iOS-compatible security system is still available for pre-order online for $278 and will ship in March. It will also be available from Staples and other retail outlets soon for $299.
