personal alert system
We evaluated how easy each app is to use and tested how long it takes for notifications to arrive on your mobile device when there is an emergency. We also assessed how well each device connects to third party smart home automation systems. We contacted each company, when possible, to assess how helpful its representatives are when resolving potential technical problems. Detection EfficiencyOur detection efficiency testing is for comparison purposes only and was not designed to replace industry standard safety certifications carried by each unit we reviewed. Perhaps the most important thing we learned from our testing is that smoke detectors have a limited range, which is one of the reasons modern building codes require a unit in every bedroom as well as in areas adjacent to bedrooms. To test effectiveness, we sprayed test smoke from an aerosol can directly at each device and timed how long it took the alarm to sound.
