Meet the PIN Genie Smart Lock: a hidden camera proof door lock with a touchscreen pad that lets you set temporary codes for your guests and open your door from a smartphone. It can even shuffle the numbers, so people can’t guess your pin code even if they are watching you.
The smart lock lets you assign up to 8 unique passcodes for your friends and family members. In Safe Home Mode, the touchscreen is turned off. There is also an alarm just in case someone tries to break in. Like what you see? This project is on Kickstarter right now.
