Automatic garage doors make a lot of sense even if you don’t garage your car. More convenient definitely but, more imprtantly, more secure.
Typically, an installation will have 2 remote controls and the option of a wall mounted switch located inside the garage.
In the event of a power failure manual operation typically involves nothing more than pulling a cord, accessible inside the garage or using an external release device if the garage door is the only point of entry.
It is also perfectly feasible to link operation to your smartphone with the option of setting the garage door to operate as you approach using your phone’s geolocation facility.
