If you want better security, you can do a system similar to mine. I put protec locks on all of my doors. I have a protec key in knob and deadbolt on all doors (most deadbolts are single cylinder but some are double cylinder. The double cylinder locks are not installed on my home, but on my detached shop since that meets life codes as it is not actually a dwelling). With the install of the locks, I reinforced the doors with security wraps and installed extra long strikes with 4" long screws to help prevent kick ins. Check out this article to show the effectiveness of reinforcing the door with wraps and installing high security strike plates

I then used a security lamination on the door windows to help prevent someone from busting the glass and turning the deadbolt thumbturn on the inside. Soon, all of my ground floor windows will have the security laminate. My second floor windows have no roof access to them so a ladder on the side of the house would be required to access these windows to break. Here soon, the upper floor windows will have the security laminate installed once I get another bundle of the film.
This is my first line of defense. My second line of defense will be a wired alarm system. I do not know which one yet but I am doing research as to what is the best and what the cost of the monitoring service is per month.
My home security is an ongoing process. After the remainder of the film is installed and the alarm system is put into place my wife wants some security cameras setup so we can see the side of the driveway and the parking area in front of the garage door along with being able to see the two back doors and the front door. I am just glad my wife is into securing our home as much as I am

You can really make your home secure if you follow some simple steps.
