We live in the country (8 Mi out) and our home is somewhat secluded(no houses within line of sight). If a person/s enter my home he will need to come through the window, which have nails inserted in frame(can be removed by hand from inside) so they cannot be opened easily(plan to make them break glass in exterior storm window and main window) , or be let in by us. "That is my plan." Any suggestions how I can do it better?
We keep all outside doors locked 99% (unlocked only when entering or exiting) of the time we are at home. I have installed shatter proof (double pain with 3M plastic in-between) Larson Security storm doors on all my entry doors with substantial locking systems and heavy metal frames.
The entry doors are all solid oak doors with one having small 12" windows half way down. I also have 2 manual locks that can only be opened from the inside, plus the handle lock and a deadbolt. My deadbolts must have a key to open them from either side. All the screws are 3 1/2 " long and screwed into the 2x6 in the door jams to guard against kick-ins. One back door, we very seldom use has locks plus a 2x4 across it (can be removed from Inside) so it can not be opened from the outside. Outside my house is and stays well lit.
My plan is to make an intruder make noise before he can enter our home. If he makes noise then my barky dog will hear and bark, there-by giving my wife and I a little notice time to react. My EDC is on me except when I sleep(on night stand). Like others, other firearms are strategically placed(hid) throughout the home. We do not have any hid on the end of the house where intruders must make entry. If they get through this, who knows?

Our most vulnerable times is entering and leaving our home.
Thinking of installing monitors(motion detector) on driveway (300' long from road) to alert us when vehicle comes near the home. Tried older game cameras, but were not able to get good pictures. Cameras may have improved over time?
I do not have a home monitoring system(cameras). What is your thoughts on them? We travel a lot and the house is empty weeks at a time.
I have done all this to try and avoid someone easily and quietly entering our home unannounced and forcing us to need to respond in a "potentially" bad situation. When children were younger, (twin daughters worked as car hops at Sonic drive in eatery) we had a man (later arrested pervert) follow one of them home, at midnight, and was peeping through windows at her sitting in my lazy boy chair(got description of car). Wife insisted/demanded I take precautions, there-by began the hardening of the exterior of our home.
All of this has taken place over time. Spent substantial money on prep(4 storm doors 1,600. outside lighting 1,000. etc). Any other suggestions?
We take this seriously!
