Battle of the Doors: Dip Switch VS Rolling code Technology
Opening our garage doors has never been as simple as we have it now. With just a click, you save yourself the (much needed exercise) stress of getting out of your car and walking to the garage door to open it, drive in, get out of your car and close it again. Do you know how it really works? The remote click thing? You don’t? Okay, let us do a crash course on garage door tech and which suits you better.
There are two ways your garage doors can be opened through a remote link.
The Dip Switch
A dip switch can be seen as a series of tiny switches that are connected to a circuit board both in your remote for the garage door and the garage door itself. Each switch can be positioned in a number of ways giving rise to different possible combinations. This makes it difficult for someone to guess your combination. In Dip switch remotes, you have u to 256 possible combinations. More importantly, each switch (remote and garage door) must be set to the same combination for it to work. Some people argue that radio scanners can be used to read the radio code that the remote control sends, making it quite possible for them to break in.
The Rolling Code
The rolling code design is a type of technological design that works with a chip. The small computer chip is present in the remote as well as the receiver. Whenever that remote is pressed, the receiver, which has a matching code, responds.
Something remarkable with this kind of tech is that it creates a new code for the next time your garage door will be opened. After creating, it sends out the code to the receiver. This means that the next time the garage door is opened; the previously created code is used. It is an awesome tech because it makes it difficult for thieves to figure out what the new code is. Both the Dip Switch and the Rolling code have their pros and cons. It all boils down to consumer preference. Whichever you feel works for you, works for you.
