The alarm system is a good idea because is a way of providing additional security, especially in a situation where we are not living alone. However the attention should not just be on protecting the hardware wallet because the most important thing is the seed phrase. Once someone lays there hands on it protecting the hardware wallet becomes useless because they can use another device to access the bitcoin in our wallet. The best thing is for the hardware wallet and the seed phrase not to be kept in the same place like beside the bed. Also it will be good not to tell anyone about were we are hiding our seed phrase or hard wallet because the less people know about it the more secured it will be. Without someone having access to our seed phrase it will difficult for them to have control of our bitcoin .
No matter how smart you are or how protected you are, you still need to be careful of what you are doing, it is not a bad idea to put an alarm or something that will notify you when someone come close to where you have your keys or something important, but we should know that people can also remove the alarm and do whatever they want to do, what we need to do is that we should never give them the opportunity of scamming us, our seed phrase is very important and it is something that we should not joke with.
They can get whatever they want and they will not find it difficult to get access to your wallet, but if they get a seed phrase they can get access to the wallet, alarm is not a bad thing but we should not let the alarm make us believe that everything is safe.
