By nature most thieves are cowards, and once you make eye contact and create a situation of potential conflict, they will go away and find easier pickin's.
Very True. Always remember, when seconds count, the police are only minutes away. That being said, I feel as though many security features give us a false sense of security. If someone wants to get in your house, they can and will. Check out the below video on Youtube about bump keys.

Not every state provides protection from criminal and civil liability if you were to shoot someone breaking into your home. Articulating that you are in fear of your life is essential, not just the mere fact that someone entered your home. This element is required in some states and can prevent civil liability in others. The saying, "I'd rather be judged by 12 than carried by 6" comes into play here.
Being able defend yourself is key. Don't be a victim in your own home. I think securing your valuables in a gun safe is one of the best ways. They can be bolted down, are extremely heavy and difficult to access. As a bonus, good ones are fireproof to varying degrees and temperatures. Depending on the police response time, if an alarm went off, it would be difficult to either breach or remove the safe before the police arrived.
I have a Mossberg 12 gauge shotgun with a pistol grip and short barrel. It is just over legal length (I don't want to get arrested should I have to use it.) The tube is loaded 2 3/4" buckshot rounds, with the dowel rod removed. It sits beside my bed every night. Racking the shotgun in itself is generally a good attention getter. Everyone knows that sound, and if they're somewhere they're not supposed to be, fight or flight is going to kick in. Chances are they will flee, unless they are armed.
Generally, burglars like to avoid conflict and are stealthy. Home invasions generally occur over drugs. A street robbery is the most unpredictable situation. These people are desperate and unpredictable. I carry a Glock 27, (.40 caliber) on my ankle when wearing long pants. Not easily accessible, but highly concealable. I have been frisked when entering events and 9 out of 10 times, it is missed! (I am a retired police detective)
Most of you, like me, live on larger parcels of land, often concealed from view. This is a double edge sword for obvious reasons. Always lock your doors to keep the "honest thieves" out. The biggest key is avoiding strangers in/around your house. For examply, my neighbors house was burglarized by someone who stopped at their garage sale the week prior. He had asked about things for sale in the garage. When he found out they weren't for sale, he returned and got the five finger discount. Many of these crimes are committed by associates of shady service people (cable, phone, electric, etc.) If you think about it, they get access to your house and can essentially shop around. Often, this information is relayed to an associate who commits the crime. I always make sure I am home when these people are in my house. I follow them around, and I tell them why I am following them.
Just throwing out some ideas. I have never been the victim of a crime, and hopefully I never am. Like someone said previously, not only are you losing your stuff, it effects you mentally. Hopefully, this helps.
