Meet the Notafire Pro: a discreet smoke alarm that uses 5 sensors to detect fire related emergencies and Carbon Monoxide early on. It measures only 4.3 inches in diameter and supports WiFi, Z-Wave, and IFTTT rules. In the event of an emergency, all Notafire units in your home will sound an alarm.
The device has an app to notify you in the event of an emergency. It also has an integrated camera to take a picture.
