Remote control?

I am very happy with the remote control for my Garmin Virb XE on a bike. Time controlled capture is better than distance based at this moment.

Do similar things work with the mapillary app ?

@filipc The external camera integration on the Mapillary (iOS) app basically functions as a remote control for the camera, and it’s there that you set the capturing interval, and start and stop the capture.

A smartphone as a button works well in the lab.
But in real life we tie the button to a steer and operate it without looking at it with our thumbs.
A real button has a good tactile feedback.

There do exist solutions to command a smartphone with an external button.
