ZestCasa Security Alarm with Door and Window Sensor: Prevents burglaries and unauthorized access
This home security alarm is for parents who want to know their kids are safe after school or for renters securing a first apartment. While many systems focus on stopping break-ins, this one gives you peace of mind by letting you check in remotely, so you can relax at work or on vacation.
The magnetic sensor triggers an alert on your phone the instant a door opens, often before a text arrives. With two-way audio, you can hear a child come home or warn off an intruder through the built-in speaker. It works with Alexa and Google Assistant for voice commands and connects via WiFi or Bluetooth for reliable monitoring. Setup is DIY with included tape and screws, and the battery lasts up to a year with low-power alerts. You get real-time notifications, no subscriptions, and can add up to 100 sensors for full coverage.
