Another thing to keep in mind is "Motion Sensor Automatic Light Switches" outside entry ways, passages, and other key areas. This lets you know better what areas to watch. These light switches can also be employed to the inside of key entry areas and certain rooms that are likely center points of a home.
Leaving certain safer rooms where you and/or your family are more likely to occupy with the std manual light switchs gives you the choice to turn or those lights or not.

...

In the odd case that your home may be some kind of 'target' of an LEO raid, it is very likely that the power,(and possibly all utilities), to the entire home will be cut off shortly before the beginning of the raid. No light switches will work at this point. Unless these motion sensor lights are set up with emergency battery/power supplies. (But then, if your power is cut off first, you bedside clock most likely will be black indicating no power to the house). The total absence of any power or other utilites in your home can tell you what you may be facing, in some cases.

...

In any case, an outter perimeter motion sensing system that is on a separate emergency batter/power supply would be recommended. One that will silently alert you in the power is cut off and/or an intruder comes within your outter bounds unbiden.

The more warning that you have to intruders of any kind, is the more ready or more scarce that you can make yourself and your family.

Hidden and concealed "Escape Routes/Passages" that are known to you and your family ONLY, can be invaluable in a great many situations.
