If you want to go for an automated home then this Insteon Automatic Door lock will help you in your endeavour.
I/O Linc’s INSTEON is a remote control door locking system which allows entry through the door by the press of a button. The system also has the ability to work remotely too, so if you are in your office and need to let someone in your home then just tell it to open and it will…. for an adjustable amount of time.
The electric door strike is hardwired to the delay timer/relay and both are powered by a power supply. The delay timer/relay is then connected to the output of the included I/O Linc – INSTEON Low Voltage / Contact Closure Interface (1 In / 1 Out), which simply plugs into an available outlet. When I/O Linc receives a signal from any linked INSTEON device, the built-in programmable relay can keep a door or gate open for up 25 seconds before automatically locking. By using the delay/timer relay, you gain the added flexibility of keeping a door or gate unlocked for up to 60 minutes. This kit gives you the control to regulate access to and from your property.

Interesting, but rather complex internally really, for a simple door lock. The remote thing is really cool though.
Can you show me how to install this device to the door..If can I want to see the picture about the installation and how to set the timer..and how about it price and catalog..
I think it’s good that they’re putting together kits for things people previously had to hack together. Thanks for sharing!
can you send us the cost and the installation process
