There are any number of ways that a person can secure their home from intruders. The idea here is to keep them from making it as far as the house by securing your yard from burglars. If they cannot reach the valuables, there is no need to worry about them being stolen.
If the house you live in is surrounded by trees and shrubs, get rid of them. There is nothing a thief likes more than objects they can use to hide behind. Keep flowers that grow close to the ground. There are many flowering shrubs that are embedded with long, painful thorns. These things add ambiance without providing cover.
Other homeowners will build a privacy fence between themselves and a neighbor. There is absolutely nothing wrong with this, even the burglars will love you for it. Now they can commit a crime because they cannot be seen by neighbors.
The main deterrent is securing your yard from burglars. Just turn on some outside lighting. It does not have to be so bright that the neighbors file complaints, but enough to light up the presence of an intruder. When they know they can be seen, they will go elsewhere. In the meantime, you can enjoy after dark activities that you never could before. You have just expanded your living area to the outdoors.
This topic cannot be expressed too often. A home with a nice lighting system installed around its exterior is a safe home. It is a way to afford you a good nights sleep, free from worry. There is only one other thing you might add to the existing system.
A number of people have installed motion sensors. They are fairly inexpensive but you should invest in one of good quality. A well made unit cannot be tripped by pesky squirrels. You can choose either an audible or silent alarm. The audible alarm will send everyone running including the robber. The silent alarm alerts the authorities to check out the premises.
Don’t waste your money on electric fences and invisible moats around the house. A thief becomes good at his trade by knowing how to bypass these things. When securing your yard from burglars, one thing they cannot bypass is all the lights. A smart thief will not attempt a robbery when there is a chance they can be seen. They will avoid apprehension at all costs.
