Door Alarm, Door Opening Detector with Powerful 130 dB Siren, Wireless Magnetic Door and Window Alarm for Doors, Windows and Cabinets, Home, Office 90x43x13mm

【With Remote Control】 The door alarm sensor comes with a remote control, allowing you to arm and disarm the door alarm, and configure arming, disarming, ringing, alarm, and emergency settings. The maximum control distance is 10 meters without interference. No battery is included. 【Easy to Install】 The window alarm sensors are equipped with specially designed double-sided adhesive tape for magnetic door locks, so no tools are required. Simply stick the adhesive tape to the back of the alarm and the magnetic strip, then attach the alarm and magnetic strip to the door or window. 【Loud 130dB Alarm】 This door and window alarm features a built-in high-volume alarm horn. A 130-decibel alarm sounds when a door or window is opened, effectively deterring burglars and preventing children and babies from sneaking out. It protects your home or office whether you're inside or outside. 【3 Alarm Modes】 The door and window alarm system has three alarm modes: doorbell, anti-theft, and reminder. Each mode has a different tone, and you can switch between them via remote control to suit your daily needs—very convenient. 【Low Battery Indicator】 This window and door burglar alarm has a low battery indicator function. When the alarm's battery voltage drops below 2.4V, the alarm will emit a "DiDi" sound to remind you to turn off the alarm.
