It seems so simple: you click on a button and your garage door opens, allowing you to drive directly into your garage Without having to get out the elements and do the work for yourself. When garage door openers were invented, people really rejoiced, especially when it became affordable for everyone to have a garage opener. But most people are not sure how they work. There are actually two different ways to open the garage door openers through a remote control link.
A DIP switch is the first type of switch that was invented to work with garage door openers. In the 1950s, when garage doors were created, all garage doors worked with the same radio signal, meaning that anyone could enter your home as long as they have Had a garage opener. This has caused tons of security problems, and that is why DIP switches were invented. A DIP switch is a series of small switches that are connected to a printed circuit board inside your remote control. Each switch can be positioned in several ways in the remote control, creating a variety of different combinations, making it almost impossible for anyone to guess your specific combination. In most DIP switches there are up to 256 possible combinations.
The switch is added to the remote control to the garage door opener, and to the unit that sits in your garage, known as the receiver. The two switches must be set to the same combination so that the door operates correctly. Some say, however, that the DIP switch door openers are a thing of the past, as some thieves can use radio scanners to read the radio code that the remote control sends to the receiver, which allows them to enter In your garage door.
A rolling code is a computer technology designed to add more security to your home through your garage door opener. This type of opener works with a small computer chip that is located both in the receiver and in the remote control. When you click on the remote control to open your door, it sends a code to the recipient, which contains the corresponding code. But it does something else: it creates a new code for the next time the door is opened and sends this information to the recipient. He then records the code. This means that when you open your garage door the next time, it will use the code that it created from the previous moment. He will have created a new code, which makes it virtually impossible for thieves to be able to figure out what the new code is.
Both types of garage door openers are on the market today and both have their advantages and disadvantages, allowing consumers to choose which garage opener they are Feel the best and this is the safest for their homes.
