Zusammenfassung:	A smoke alarm system comprising: a controller, a smoke detector, a recording device comprising a camera device, a reminder device and a memory, wherein the controller is connected by electrical communication to the smoke detector, the recording device, the reminder device and the memory. The smoke detector sends a signal to the controller when it detects that the smoke concentration is higher than the threshold. The controller begins to take photos and/or record videos when it receives the signal sent by the smoke detector. The photo and video content is stored in the memory. At the same time, the reminder device sends out a pre-stored reminder message, wherein the reminder device comprises an optical reminder device and/or sound reminder device.
