In this mode, illumination is not available. Most front facing cameras do not have auto focus and illumination, and provide significantly lower resolution images. This is an unusual, but possible configuration.

Please place this code in initDevice() in the Activity before you init connection to Phone Camera:įRONT_CAMERA: This initializes the reader to use the mobile front facing camera of the device, if available (not all mobile devices have a front camera). With the following code: self.readerDevice = CMBReaderDevice.readerOfDeviceCamera(with: ontCamera, PreviewOptions:CDMPreviewOption.init(rawValue: 0), Replace the line in func createReaderDevice() self.readerDevice = CMBReaderDevice.readerOfDeviceCamera(with: CDMCameraMode.noAimer, In the ScannerController of our sample iOS app, replace: readerDevice =
Most front-facing cameras do not have auto focus and illumination, and provide significantly lower resolution images. KCDMCameraModeFrontCamera: This initializes the reader to use the front facing camera of the mobile device, if available (not all mobile devices have a front camera). In order to proceed, follow these instructions: Yes! However you should first make sure that the front camera is of sufficient quality for successfully decoding your targeted barcodes. ReaderDevice.getDataManSystem().sendCommand("SET MSI.CODESIZE ON 5 20") ReaderDevice.getDataManSystem().sendCommand("SET C93.CODESIZE ON 5 20") ReaderDevice.getDataManSystem().sendCommand("SET C39.CODESIZE ON 5 20")

In order to mitigate such cases, we have set a default minimum character length for those barcode types. This can lead to false detections whenever a code is encoded with four or less characters. Using cameras with lower specifications will decrease the likelihood of achieving a successful scan, especially on complex barcode types and images.Ĭodabar, Code 11, Code 25, Code 39, and MSI Plessey barcode symbologies have weak or non-existent error protection and checksum. Keep in mind that these settings could be CPU taxing for older, slower devices.Ĭamera specifications - Check if your device has a camera with minimum requirements - Autofocus (AF) support and 5 megapixel (MP) capture is recommended minimum. Try increasing the resolution and scanning effort level to 3. High-density barcodes - If you are trying to scan high density and complex barcodes it may be inefficient to use low resolution camera buffer images and lower scanning levels.

readerDevice.getDataManSystem().sendCommand("DECODER.EFFORT 2") - This example is for Android Try using lower resolution camera buffer images and a lower scanning effort level (2 is recommended). Slow mobile devices - On older mobile devices with slower processors, scanning can be laggy and inefficient. There are several possible reasons that you might experience slow or incomplete decoding on mobile devices with cameras:
