It is inconvenient to carry the remote control of the sliding door in my home, and it is easy to misuse or lose it. Is there any other way?

　　You can install a set of card swiping device to give some cards to the person who has the right to enter and exit. Every time you enter the door, just swipe the card, and the door will automatically open. If you feel that the card is also a burden, you may wish to set a password, so that you do n’t need to take anything with you. Press the password door before entering the door to open it; to prevent the password from being stolen, you can change the password setting at any time.
