Whenever someone mentions home security to me, I think back to the days many years ago when when all it consisted on was putting a chain on my front door. That has all changed now, especially with the advancement in electronics.
No longer do we need to worry about our property, it is now possible to secure it for a reasonable amount of money. Multiple locking doors are a real deterrent as they are very difficult to break, but the best is the alarm which comes complete with cameras. I installed one of these last week, a very simple process.
