Intruders usually try to break into the house from through a door or window. That is why it is better to use door and window sensors to alert you about any attempt being made to break into your home.
The 2GIG DW10-345 Wireless Thin Door or Window Sensor can be easily installed on any door, window or for that matter anything that opens and closes. These sensors send signals to the control panel whenever a magnet placed close to the sensor moves away from it. This happens when anybody tries to open it. In this manner the alarm alerts the person of an imminent danger.
