Access Control For The Home

If you work for a business, you most likely have to present some form of ID or swipe a card in order to get inside the building. This security measure has long been the choice for companies to ensure that only authorized personnel are able to get in. For the homeowner, this technology can be utilized to help maintain the safety and security of their home. Instead of a traditional key, a thin card about the size of a credit card is swiped or tapped onto an electronic reader, unlocking the door.


The three main components to a home card access system are the card reader, door hardware, and the proximity cards. The reader is attached to special hardware on the door, where the resident will swipe or tap their proximity card in order for the door to open. Once the reader recognizes the card, the door will unlock, allowing access. Software is installed, which identifies the information from the card to the reader. This software allows the homeowner to designate cards to different people, and can even allow access only to certain doors if there is more than one reader for several doors.

A quality card reader system and its software provides more than just simple access. High tech systems can also generate reports that show the homeowner when people gain entry, how often, and exactly who is coming in and out. It even allows certain times to be entered so that people can only come in during particular hours. This solution is perfect for people with large families and larger homes, or for those with staff who need to get in only during the day such as nannies or housekeepers. It allows the user to see in real time who is entering their home, and how often. 

How it Works

The reader installed on the door reads radio frequency waves transmitted from the card. There is usually a small antenna either attached to or inside of the reader that picks up the radio signals. Once the reader recognizes that the card's specific frequency matches, it will release the door hardware, allowing it to open. The person with the card must be close enough to the reader for it to pick up the signal. Some models require the cardholder to swipe the card, while others just need a simple tap. Once the reader "sees" it is an authorized card, it sends the current to the door hardware, unlocking it.
