Wireless Window Door Magnet Alarms Magnetic Sensor

Our security alarm with built-in magnetic sensor detects the opening of a window or door and chirps rapidly at 90dB once being triggered off. Each part of the alarm has an attached strip of double-sided tape that makes installation easy and fast with no need for any tools. You can attach it onto windows, doors as an intruder alarm or onto gun, medicine cabinets to alert you when kids are opening._x000D_
