Something to consider: Embracing technology to make your life easier can with the right setup make your home easier to defend. We, like many homes have our home integrated with smart devices. One of those is an Alexa 8" touchscreen in the bedroom. We can use it to control every light in the house, watch all the video cameras in and around the house and listen in through any of the other devices in the house. You can also set up custom command controls, like a panic command that will cause the house to perform certain functions like turn on all the lights to their brightest and call the police.
Or, if you are crazy, you have it turn all the lights in your house red, announce "Shooter Ready", play the shot timer beep then start playing "Let the bodies hit the floor" through all of your speakers...
Kidding on that last one. That's lawyer bait.
Anywho, the point is that a good defensive plan should incorporate every possible advantage. No one who ever won a life and death fight ever complained because the odds had been stacked too far in their favor.
