For inside your home, consider a DC powered independent security lighting system. Mine is outdated technologically, with it's first generation LEDs that are nearing 25 yrs old. Still useful and reliable, but any system I replaced it with today will be easier, cheaper and probably more reliable.
I now have 3 control points, 2 of which are shielded by internal wall hardpoints.
This all seemed a bit over the top til we had our first neighborhood swat raid last spring. Seems the new nearest neighbor runs and does "business" with the wrong crowd.
This summer I put in all new external motion activated security lighting on the outside as well. The outdoor system has no independent power source, and critters even the size of a coon can be a nuisance, but it gives some peace of mind.
