So, What do you do to insure that your home is safe? If possible, I would prefer to NOT have to defend my home and family with force or as a last resort deadly force. With that said I will but would like to have a good amount of deterrence for your more common home invaders. There is a large variety of options out there and I would like the input of people that I think have the same mind set as me with experience... There are alarm systems, security doors, motion sensor lights, video monitoring etc. I would love to have a dog, but currently that is just not an option. The reason I ask is I will be moving to an area where I can foresee the benefits of adding some type of additional security. As far as my family goes, we have set a good habit to lock all doors/windows when not home or sleeping. We also leave a talk radio station on while away to mimic someone home. Call me paranoid, but I just want to be extra safe...
So far this is my what I plan on adding: (recommendations are welcome

)
1. One way screw security doors (heard stories from my father who is a retired Firefighter who says that they are extremely difficult to open when locked, even with the tools they use)
2. Outside motion sensor lights
I'm on the fence in regards to investing in a home alarm system. (won a DSC alarm system from the gun show

). The reason I'm on the fence is that there is a monthly fee and I've heard good and bad reviews when it comes to home security systems. Some say it gives peace of mind, while others say that it causes more issues (false alarms) than it is worth. Any personal experience anyone?
