Interesting topic... We also spent some time dealing with the subject of "door," "security," "security lock," "security glass," "security locking cylinder," "automatic lock with A-opener," or "proper motor lock" and "alarm system" during the house construction. Ultimately, the price difference between an A-opener and a proper motor lock was no longer that big, so we finally decided on the fully motorized solution. We got our aluminum door back then from a well-informed dealer who was able to show us both types of locks. The door comes from "Kompotherm" and we like it very much. The installation went flawlessly. For over a year we have not needed keys anymore, thanks to the possibility of opening the door via the built-in fingerprint. The motorized locking position is queried at any time during our absence via an Abus alarm system. Both control units are wired together. We are very satisfied with the entire system and are glad that the door shop pointed us to this solution. Unfortunately, you find too little information about these comfortable and secure options in trade magazines, and the advice of some "specialist dealers" could also be better. Regards
