GoPro sold 5.2m units in 2015 Q1, that's 57,777 units per day.
If IOT is even 1/7th of that, they would be producing at maximum capacity (50,000 units per week).
1/7th of 1.5bn is 214m.
This is just a bit of perspective seeing there are discussions on GoPro comparisons here, don't look too deeply into it
