The camera doesn’t look like its using the standard features for software triggering.

You first need to get the node map from the device as shown here:

Also the feature nodes are mapped by their actual name and are not made pythonic. Try something like:

```auto
device_node_map = vin_device.node_maps['Device']
sw_trigger = device_node_map.outputLineSoftwareCmd
sw_trigger.execute()

```
