There are several simple and low cost security measures that anyone can put in place around their home to greatly enhance their security. And usually it's a good idea to put some of these common sense measures in place first when you give attention to home security. But after you have done all that you can to reduce the likelihood of someone breaking into your home otherwise, it's a good idea to start seriously thinking about installing a home security system as well, especially if your budget will allow it.

To start with, an alarm system can just consist of sensors that are placed on all the windows and doors that are connected to a main system. When armed, if any of those sensors detect an opened window or door, it alerts the system which begins a countdown of a set number of seconds for the alarm to be deactivated by the owner if returning home, until it sounds a very loud siren to warn of a possible intrusion. This kind of relatively simple alarm system has been in use and proved to be very effective for many years now.

But advancing technology has made other additions and enhancements available that can improve your security level even further.

For instance, now you can add motion detectors to a security system to make it even more effective. By putting motion sensors inside the home, even if the thief manages to bypass the entry sensors, they will still be caught by their movement inside the home and the alarm will be triggered.

Another increasingly popular option is to connect the alarm system to an outside monitoring service that will determine if an alarm being triggered is a real emergency or just a false alarm, and in the case of a real break-in will report that to local law enforcement. Most of the time the connection with this service has been made through regular phone lines, but recently some companies have started using cellular phone service instead. This eliminates the possibility that someone could cut the phone lines in advance and prevent notification of the alarm service, and it also allows alarm monitoring even when the power is out if the security system uses a backup battery in such situations.

Another increasingly popular addition to home security systems is video surveillance of the outside of the home. The low cost of security cameras has made this kind of option more affordable than most would initially believe. By installing small, discreet cameras at strategic locations outside the home, you can monitor what is going on and even record it if you wish. These cameras can also be connected to motion sensitive devices so that they alert you when movement is detected and can begin recording upon being triggered. There are plenty of things that can be done with video cameras to enhance a home security system, but this should give you a few ideas of what is possible though.

So do you need these added security enhancements? As with many questions involving consumer purchases the answer is maybe. If your budget simply doesn't allow for them at this point, then a simple alarm system is certainly better than none at all. But if you can afford to install some of the options mentioned above as well, it can be a good investment that helps promote more peace of mind.
