Although, smoke detectors are far from accurate. - Based from our own research via Interview, they say smoke detectors are pretty useless for detecting smoke, I also dont know if there is a backup-power source or like a 10 year battery life span

P.S.: I dont know what Carbon Monoxide is, is it a combustible material? If it is would they not going to be late? I even dont know, why this product has been featured at the top 10 already, are these people do even know how meaningful comments should be?

Anyways, the concept and the goal is great - 'to save live in times of danger' Well come even have an automatic sprinkler system without using an iot device. Which the fuse of each sprinkler has a unique way for turning on the sprinkler and that if the room is really-really hot, the water sprinklers will turn on, simple and easy solutin. The disadvantage that the some dont building inspectors wont really check the flaws of the security and fire .
