You can toggle this a few ways, use contraints to set preferred camera or use useDevices to select the camera you want (add code to to select the camera you want)

`

export function QrCodeScanner(p: {
onScan: (decoded: string) => void;
onError: (error: string) => void;
}) {
let x = useDevices();
return (
<Scanner
onScan={(res) => {
console.log({ res });
p.onScan(res[0].rawValue);
}}
onError={(err) => {
console.log({ err });
}}
paused={false}
components={{
onOff: true,
audio: true,
finder: true,
zoom: true,
torch: true,
tracker: outline,
}}
constraints={{
facingMode: {
ideal: "environment",
},
deviceId: "",
}}
/>
);
}
