The products we reviewed are cutting edge devices made for 21st century homes, and they all have mobile apps. While researching for this comparison, we looked into the differences between the sensors each smoke detector uses and found research from Underwriters Laboratories UL that suggests you should have both photoelectric and ionization type smoke detectors in your home since each type is suited for different types of fires.
