Build your own alarm system for use at home or your business.

• Take it with you when you travel or move to another location.
• You can build your system as simple or as complex as you need to fit your time and budget then expand later.
• The begining cost can be less than $100.
• You do not have to be a technical expert, just use basic hand tools.
• Most can just be placed on a table or night stand, install a battery and switch it on. You are now protected from anyone approaching your area undetected.
