Protect your home with our easy-to-install Wireless Door Window Alarm. This compact and powerful security device provides peace of mind by instantly alerting you to unauthorized entry, keeping your loved ones and valuables safe.

Key Features:

  • Loud 90dB Alarm: Deters intruders with a piercing 90-decibel siren, alerting you and neighbors instantly if a door or window is opened.
  • Effortless Installation: Simply attach the two magnetic components to any door or window frame with the included double-sided adhesive. No wiring or complex tools required! Ensure a gap of about 10mm between the main and auxiliary parts for proper function.
  • Wireless Convenience: Operates on a stable 433 MHZ wireless frequency, offering a strong signal up to 120 meters (without barriers) for flexible placement throughout your home or shop.
  • Long-Lasting Battery Life: Designed for energy efficiency with an alarm current of <=15mA and a static current of <=10uA, significantly extending the life of your AAA batteries (2x AAA batteries required, not included).
  • Durable & Reliable: Engineered to perform in a wide temperature range from -10℃ to 55℃, ensuring consistent security in various climates.
  • Compact Design: Measuring 23x13x60mm (0.9x0.5x2.3in), its discreet size blends seamlessly with your home decor while providing robust protection.

How it Works: The alarm system consists of two parts: a main unit and a magnetic auxiliary unit. When a door or window is opened, separating these two components, the 90dB alarm will activate, scaring away potential thieves and notifying you immediately.
