【With Remote Control】 The door alarm sensor comes with a remote control, which you can use to arm and disarm the door alarm, and configure the arming, disarming, ringing, alarm, and emergency settings. The maximum control distance is 15 meters without interference.

【Easy to Install】 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 stick the alarm and magnetic strip to the door or window.

【Loud 130dB Alarm】 The door and window alarm has a built-in high-volume alarm horn. A 130-decibel alarm sounds when the door or window is opened, which can deter intruders. Deter thieves with force, prevent children and babies from secretly leaving the house, protecting your home or office whether you are inside or outside.

【3 Alarm Modes】 The door and window alarm system has 3 alarm modes: doorbell mode, anti-theft mode, and reminder mode. Each mode has a different sound, and you can switch between the 3 alarm modes via remote control according to your daily needs—very convenient.
