Product Information

About this item

• 【DOOR CHIMES WHEN DOOR OPENS】Stay aware of door activity around your home. When a door opens, the indoor door chime immediately sounds a clear chime. Whether a child opens a bedroom or front door, or an elderly loved one with dementia tries to leave alone, you can hear the alert and respond quickly, adding extra peace of mind for families with children, seniors, or loved ones who need additional care.
• 【DOOR ALARMS WHEN OPENED】Get alerted when a door or window opens unexpectedly. The door alarm can sound a loud alarm up to 110dB to draw attention and help deter potential intruders, while a notification is also sent to your phone. Whether you are asleep at night or away from home, you can stay informed of unusual activity and add extra protection for your family and property.
• 【DOOR LEFT OPEN ALARM】Reduce unnecessary alerts during normal entry and exit. In Delay Mode, brief door openings will not trigger an immediate alarm. The alert activates only when the door remains open beyond the preset time. Ideal for front doors, back doors, garages, storage rooms, patio doors, and other areas where doors may accidentally be left open.
• 【2.4GHz WI-FI】Supports 2.4GHz Wi-Fi only; 5GHz Wi-Fi is not supported. Once connected, you can stay informed through the app even while at work, traveling, or away from home. App push notifications are free; phone call and SMS alerts are available with a paid subscription. For reliable remote notifications, keep the door alarm connected to a stable Wi-Fi network.
• 【2 ALERT METHODS】Two ways to stay informed: the wireless door chime provides an immediate local chime when you are at home, while real-time app notifications help you stay updated remotely when you are away. Whether at home or on the go, you can stay aware of important door and window activity.
• 【BATTERY & CUSTOMIZABLE VOLUME】The door sensor is powered by 1 AAA battery and offers up to 2 years of battery life, reducing the hassle of frequent battery replacement. The door open alarm features 20 chimes and 5 adjustable volume levels from 0–110dB, including mute mode, so you can choose the right sound and volume for bedrooms, living rooms, stores, offices, and other environments.
• 【DEVICE SHARING】Share the device with family members or caregivers so multiple people can receive app alerts. When you are working, traveling, busy, or unable to check a notification right away, other family members can receive the alert and respond when needed, reducing the chance of important notifications being missed.
• 【EASY INSTALLATION】The sensor and door chime are pre-paired and ready to use. Mount the sensor with the included 3M double-sided tape—no wiring, drilling, or tools required. Suitable for homes, apartments, rentals, stores, offices, and more. Not recommended for metal doors.
