Home doors and windows are the two most likely entry points for burglars and intruders and hence need to be secured. Door and window alarms function as an important home security system. They are placed on the doors and windows, and sound an alert when the doors and windows are opened. The simplest type of door and window alarms are those that are fitted along the door and window frames, with magnetic contact strips. If the contact is broken, an alert is sounded at the control panel or call center. They, in turn, alert the authorities. Advanced technology has led to the invention of many innovative home door and window alarms, like the keypad type door and window alarm. This type of alarm is mounted near the door or window, and requires a code that activates and deactivates it. A doorstop is a common type of door alarm that is placed at the bottom of a door and sounds an alert when the door is opened. Window alarm systems alert the residents in case the window is opened or tampered with, and in case of glass breakage and glass vibration as well. Door and window alarms not only prevent criminal intrusion but can also be helpful to keep unsupervised small children within the premises of their home.
