Electronic locks and bells

Today's technology makes possible to anyone to connect to his home and control the electronic lock from anywhere in the world through the Internet or his mobile phone internet provider. Of course, you can always use your keys to open the door. No more keys under the doorstep or the pot with the flowers...
Associate the lock with the door sensor, the lights, the camera, the siren and start building your security system tailored to your home and actual needs.
Install a wireless bell and you can monitor all visitors while you are away (associating the camera pictures with the door bell).
Finally, be informed of all the above through mail in your mobile phone.
