You can select to have a wired or wireless system, setting off the alarm when an intruder attempts to open an entry way, or when there is movement inside your house while the alarm is armed.
More options ... open circuit or closed circuit. With a closed circuit system, when a window or door is opened, the circuit is broken and the alarm goes off. As expected, an open circuit system works the opposite way, with the circuit being completed when an entry way is opened and the alarm is set off.
As the name suggests, motion sensors can sense when there is motion within a certain range of it. When it senses the movement, it will send a signal to the control panel which will analyze it and determine whether it is a suspicious kind of movement or not. The control panel will react by setting of an alarm or notifying the authorities if it decides that the movement is of a suspicious nature.
To reduce the chances of a false alarm, the motion sensors can be set to ignore movement from pets walking around or other common activity in your home. Motion sensors are becoming more common and is a great way to protect your home.
The ideal situation would be to have a combination of magnetic switches on the door and windows and motion sensors inside rooms and hallways. Two other options that would make up a complete security system are to add a video camera system and finally have a security company that monitor your system for you and offer a quick response service.
