About this item
  • 【Door Chimes when Door Opens】Whether you are relaxing at home or busy around the house, this door sensor chime alerts you the moment a door opens. If a child opens a bedroom door or a loved one with dementia tries to leave, you will hear a clear chime right away—helping you stay aware of their movement, respond quickly, and feel more at ease.
  • 【Door Alarms when Opened】When you are away from home or asleep at night, this door alarm sensor helps alert you when a door or window is opened unexpectedly. It can trigger a loud alarm up to 110dB to help discourage potential intruders, while also sending a notification to your phone—so you can take action quickly and add extra protection for your family and property.
  • 【Door Left Open Alarm Chime】Use delay mode to remind you when a door is left open. During normal entry and exit, it stays silent, so it won’t disturb your daily routine. If the door is still open after the preset delay, the alarm will sound to remind you to close it—helping prevent security issues caused by a door being left open, whether you are stepping into the storage room, garage, or back yard.
  • 【2 Alert Methods & 2 Alert Modes】This WiFi door chime gives you 2 alert methods: real-time app notifications and a loud indoor receiver chime, so you can stay informed whether you are at home or away.It also offers 2 alert modes—instant alert gives you real-time notification when a door opens, while delay alert offers more flexibility during frequent entry and exit.
  • 【Device Sharing】Share app notifications with family members or caregivers, so more than one person can monitor door activity at the same time. When you are away, at work, or unable to check alerts right away, others can step in to help. Caring for a loved one alone is not easy, but shared alerts help family members stay involved—bringing more support, less stress, and greater peace of mind.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
