LiftMaster is the professional grade brand of Chamberlain Group, the Illinois company that also owns the Chamberlain consumer line, and its garage door openers, gate operators and commercial door systems are sold through authorised dealers and installers rather than retail shelves. Its products are built around the myQ platform, which adds Wi-Fi control, activity history, scheduled closing and, on newer models, built-in video to the garage. LiftMaster openers use the Security+ 2.0 rolling code radio and support Amazon Key in-garage delivery.
