How to use the rear camera on smartphones?

[Sixbitunder]

if you want to make the rear camera the default one you can modify the Instascan.Camera.getCameras() function in this way:

Instascan.Camera.getCameras().then(function (cameras) { if (cameras.length > 0) { scanner.start(cameras[1]); } else { console.error('No cameras found.'); } }).catch(function (e) { console.error(e); });

by default the cameras[0] is the front one, so if you change it to cameras[1] it will start from your rear camera.

Ok! Tks!

@Sixbitunder Don't you mean if (cameras.length > 1) { ... } though?

@drikusroor The cameras is stored in an array that's why we start at 0

As I suspected the above code
Instascan.Camera.getCameras().then(function (cameras) { if (cameras.length > 0) { scanner.start(cameras[1]); } else { console.error('No cameras found.'); } }).catch(function (e) { console.error(e); });

causes the application to fail on laptops with one camera using Chrome.
