While I agree with Carry Conceal gun for various reasons on your person....
I see no reason to hide the alarm stickers , let them know you are training.
If they are determined enough and intelligent enough to form a plan ( meaning staking your house , watching your patterns , learning more about you ) to get around the alarm , your training , knowing you are armed and dangerous ... then they are going to find a way to do it. And/or may get lucky even if you have that extra surprise for them.
On the other hand ... Letting them know in advance how well prepared you are , may deter them from even TRYING to do it.
I guess it all depends on just how smart/dedicated and Mission impossible determined these guys are.
