Action camera's

On the gopros you can do the remote wifi switch on, where u can use the external remote or smartphone app to trigger them all on in one click. If I had more than two on my bike I'd consider trying it out

The Laptimer App that i use has a function to link the GoPro's and trigger them when you cross the start line

That's pretty cool! What's the App, Jamie?
