What are the differences between updateScanSettings/updateVideoSettings/updateRuntimeSettings ?

« Back to FAQ index

updateScanSettings is used to update the ScanSettings interface. This can be used to configure settings such as ignoring duplicate reads, setting sound/vibration when a barcode is scanned.

updateVideoSettings is used to update the MediaStreamConstraints that define most of the video information such as width, height, and the camera facingMode (i.e. front or rear camera).

updateRuntimeSettings is used to update the RuntimeSettings interface. It updates the runtime settings with a given object or use the string speed, balance, or coverage to use our preset settings for BarcodeScanner. The default setting is speed.
