Blueguard lets you open doors by merely approaching

Hitting a button to open your garage door is a lot of work. Work that you shouldn't have to do in this day and age. That's why it's great that the Blueguard exists.

With the Blueguard, you simply get within 33 feet of your garage door and it opens like magic. It uses Bluetooth wireless technology to determine when you're in the area, and you can set it to work when you're walking up or require a full vehicle to be approaching to get the job done. But either way, that's one less wasteful arm motion you'll need to perform every day.
