All good advice. eerything was covered,
If you use the concentric rings of security, you start with:
*The perimeter (fence is good start),
*Then, between the fence and the house your next layer would be something like a dog, motion detection light, neighbors, etc,
*Move to the next layer and secure the building (doors, windows, etc. by keeping them secured and/or monitored by an alarm system)
*Then move to the inside (using anything from electronic systems, or if you prefer, guns
Burg systems are pretty cheap if you can find someone locally to by you one wholesale, and they are not hard to install.
You can go with someone like ADT or something like that, but they get you on the monitoring fees. Buy one and install it yourself and just put in a nice loud siren and you don't need monitoring (unless you want the peace of mind for your family when you arent't there).
