User blog comment:ThatGreenandOrangeGuy/What would you do, when you're trying to upgrade home security to keep burglars and thieves out?/@comment-31165208-20170724165436

Use a complex security code in order to get in my house (like a number lock with an unlikely/unpredicted password)) and if they get in, an alarm will go off. Not foolproof, but it will do!
