Another smoke alarm company, Kidde, has developed a subscription-based service that charges users in the US $5 (£3.71) per month for access to a fire monitoring service linked to the Ring doorbell app. "Trained agents can request emergency help and alert a customer's emergency contacts in the event of an alarm," explains Kidde on its website.
Innovations in recent years to make testing methods more sophisticated include thermal imaging, light analysis using lasers, and DNA profiling.
