I've noticed other camera brands such as Wyze are programmed to detect the sound pattern of standard smoke and carbon monoxide alarm signals, and a notification is sent to notify the user in the app. 

Regarding the Tapo C200, for example, it can only detect baby cry. 

It should be a simple fix to improve the sound detection, including it to detect fire alarms. If this would be improved, there would be no need to buy a "smart smoke detector", instead you could use a simple smoke detector and let Tapo camera alert you if it goes on.
