Magnetic window alarms use magnetic contact sensors to detect the unauthorized opening of windows. The sensors consist of a magnet and a contact. They are usually covered in plastic. They can also be used to protect doors and cabinets.
Magnetic window alarms have a slim and compact design not easily recognizable. They are powered by batteries. They are activated and deactivated using an internal hidden switch. Electronic window alarms
Electronic window alarms use light and motion sensors to detect the unauthorized opening of windows. They are highly sensitive and usually produce loud sirens. Aside from alarm sounds, some models feature flashing LED lights. They are usually powered by batteries.
Acoustic sensor: Choose a window alarm that comes with an acoustic sensor for detecting physical and acoustic vibrations. This type of window alarm is designed to go off even with the slightest physical movements, deterring intruders from completely breaking into the window.
