User reviews are both limited and uninspiring, though, so we think the Nest is a better bet for most, for now. One plus compared to other smart smoke detectors is that it contains both ionization and photoelectric sensors for detecting all types of fires. One minus is that while this smoke detector can be interconnected with other units to form a network, that network is hardwired. That means that installation can be a challenge unless it is part of a major remodeling job, or in new construction. Fires are always alarming, even terrifying. They kill people and ruin families with their destruction. It is critical that we enhance fire safety awareness and use firefighting equipment intelligently to minimize losses and damages. Smoke detectors are automated sentries, able to detect smoke in real time. If the density of smoke exceeds a predetermined threshold, a smart smoke detector will send information to the backend management platform and activate related devices such as alarm bells. The platform will then automatically send the information to the corresponding departments and alert the right personnel by voice messages or SMS. The increasing need for fire safety devices is influencing the adoption of smart smoke detecting systems in the commercial sector.
