Home security systems can be very useful, of course.
++++++++
They sure are good at scaring off all those white burglars that are terrorizing neighborhoods across the country. /s
LOL
Actually, they are good for the worst of the worst too.
We have a pretty good system..
Motion sensor lights around the house (thugs are like cockroaches; they do not like the light of day).
Cameras recording 24/7 and taping all motion, also which can be accessed via smart phone.
Motion sensors on the gun safe tied directly to the police.
Motion sensors on every floor of the house.
A screen system on the windows which has a wires running through it, so that if the screen is cut, it will trip the alarm.
And other things I will not post publicly.
But if someone gets through all of that.....then they get to meet me who carries 24/7.
Good luck Mr. Thug.
