The RoadWatch and Road AI cameras will pulse a barrier for 2 seconds, regardless of the pulse time set on the camera
To change this value, you need to modify the ANPR app settings
Export the settings.json file
Then open it in Notepad and modify the 'action Timeout' value to the value in milliseconds the alarm output should pulse for
e.g. 5000 is 5 seconds
Save the settings.json file and upload it to the camera
Then step and start the app to restart it
