Door and Window Alarm Security Wireless Home Anti-theft System Magnetic Sensor Protection Gadgets

Wireless door and window alarm that triggers a 90 dB alert when entry is detected. Uses a magnetic sensor switch to monitor openings—simply peel and stick the sensor to any door, window, or surface, then attach the magnetic strip to the moving part. When the magnet separates from the sensor (indicating an opening), the alarm activates immediately. The on/off switch lets you arm and disarm as needed. No wiring or installation tools required—adhesive mounting works on doors, windows, cupboards, toolboxes, and more. Portable design makes it practical for renters, temporary setups, or travel protection. Use this in bedrooms, offices, apartments, hotel rooms, garages, or storage areas to deter unauthorized entry when you're home or away. Good fit for anyone wanting basic perimeter alerts without professional installation.
