YisTech Wifi MC 1T2 WiFi Door Alarm System with Phone App: Remote alerts via smartphone app
For the busy family managing a household with young children or an elderly parent with dementia, this smart door sensor offers a simple way to know when someone enters or leaves. Instead of just focusing on home security, it provides peace of mind by keeping you connected to your loved ones' movements, whether you're in the next room or across the country.
When a door opens, the gateway sounds a loud, clear chime and your phone instantly buzzes with an alert. You can choose from 32 ringtones and adjust the volume up to 110 dB, making it effective even for those with hearing impairments. The app lets you share alerts with family members, so everyone stays informed. For example, if your child tries to sneak out after bedtime, you'll get a notification before they reach the driveway.
