We have a wide range of ***ion for Smart Smoke Alarm series. User can *** built-in cameras or PIR detecting. It is powerful and able to be used widely on fire-fight calling and emergency calling. There is no need for human monitoring, reducing management costs, improving management efficiency, and saving human resource costs. Our product will set off audio-enable or voice-enable alarm as well as smoke detecting and temperature detecting dual functions. When smoke of temperature higher than 50 degrees Celsius is detected, the alarm will go off, and it will take pictures as well as notify backend managers. The alarm stops automatically as the temperature drops to below 50 degrees. The alarm will also go off when it detects people passing by. For example, we can set a notifying sound during daytime when visitors pass by, and switch to anti-theft alarm sounds during the night.
