#1 Timers.
Timers can be used for lights, cameras, and all sorts of action. When it appears that there is action or movement in the home, a burglar is less likely to make a target of it. By using different timers, a radio can come on in one room, turn off, and then a set of lights and television could come on somewhere else in the house. This all adds to the illusion of someone being in the home during times of homeowner absence.
#2 Window and Door Alarms
Great for making lots of noise if the bad guys make it in. These types of alarms are pretty inexpensive and easy to install.
#3 Alarm System.
Monitored, unmonitored, with security cameras, or without. The choices for home alarms go on and on. The main thing is that you have one, and advertise it with a sticker on your door window.
#4 A Barking Dog
Its a proven fact that the sound of a barking dog scares bad guys away. If you don’t want the dog, you can always get a beware of dog sign, or invest in the popular and life like Barking Dog Alarm.
#5 Self Defense Products
Its not a bad idea to carry some pepper spray, stun guns, and personal alarms around the house just in case. Sometimes criminals scope out people and not just the houses they live in. They are less likely to attempt to victimize someone who is well defended. Its your job to make sure they know just how defended you are.
