With Remote Control: The door alarm sensor comes with a remote control, allowing you to turn the alarm on and off, and configure disarming, arming, ringtone, alarm, and emergency settings. The maximum control distance is up to 15 meters without interference. Easy to Install: Window alarm sensors are equipped with double-sided adhesive tape designed for magnetic door and window locks. No tools are required. Simply attach the adhesive tape to the back of the alarm and magnetic strip, then mount them on the door or window. 130dB Loud Alarm: The door and window alarm features a built-in high-volume alarm horn. It emits a 130-decibel sound when the door or window is opened, which helps deter intruders and prevents children or babies from leaving the house unnoticed, providing security for your home or office both indoors and outdoors. 3 Alarm Modes: The window and door alarm system offers three modes: doorbell mode, anti-theft mode, and snooze mode. Each mode has a distinct sound. You can switch between the three modes using the remote control according to your daily needs, making it highly practical.
