Home alarms are thought of being an integral aspect of home security. Their main job is to caution you when there is an access violation. On the market today, you can find a wide variety of alarm systems, from the $10 do-it-yourself alarms to those which are sophisticated and expensive. Today, with the advancement of surveillance technology, you can even make use your own PC to build a simple but powerful alarm system.
Turning a PC into a burglar alarm can be accomplished by using a special software and a web camera (or an analog camera). The software will also function as a motion detector by noticing the changes of the images captured by your webcam. It depends on what you want to protect, if you want to be warned everytime there is a movement passing through a window then you need to direct the webcam to the window.
Depending on the type of the security camera that you use, you can even set up a wireless alarm system. This can be achieved by using a wireless analog camera. A stand-alone power source is normally included in such a camera so you do not have to connect the adaptor of the camera to a wall socket.
Now, what kind of alarm signal you will receive? Depending on the surveillance software that you use, there are various types of alarm signals. Usually most software have already provided some audio files (e.g. in the form of siren, dog barking, etc). Just choose the one that will be generated once a movement is detected.
Of course you can also use a pre-recorded warning message. This is a good choice to scare off intruders. However keep in mind that the the quality of the sound will also be affected by the quality of your speakers.
To prevent false detection some webcam security software also provide features like Alarm Delay. With Alarm Delay you can configure the alarm system not to generate warning messages when it detects short duration motions. Another useful feature which is also commonly provided by a surveillance software is Sensitivity Level. Just make some experiments to find out the proper settings that will fit your situation.
