# When is singleFrameMode enabled?

## Version 10 and above
SingleFrameMode can be enabled by calling the api from the camera enhancer module. Check
[singleFrameMode](https://www.dynamsoft.com/camera-enhancer/docs/web/programming/javascript/api-reference/acquisition.html#singleframemode) for detailed information.

## Version 9 
`singleFrameMode` is enabled in the below two scenarios -

1. When using the library from a non-secure origin (no HTTPS).
2. When using a browser that doesn't support `getUserMedia/MediaDevices` API that is required for video streaming. To confirm whether or not your browser is supported, please refer to the [System Requirements](https://www.dynamsoft.com/barcode-reader/docs/v9/web/programming/javascript/user-guide/#system-requirements) section of the user guide.
