The smart smoke detector is a photoelectric (optical) smoke detector that enhances the safety of your home. When a fire breaks out and the powerful 85 dB alarm is triggered, the smart smoke detector sends this alarm in real-time directly to your smartphone. This allows you to take action even when you are away. Unlike conventional smoke detectors, the smart smoke detector alleviates this concern by sending real-time alerts to your smartphone and those of your family members as soon as smoke is detected. Simply install the wireless smart smoke detector on the ceiling in any bedroom, children's room, and hallway, download the app, and you can protect your home from fires. It's that easy.
