Thank you for this plugin, we can use our Chinese PTZ camera with it via RS485 connection.. I do encounter the VISCA stop code not being effective if holding down the direction & zoom keys in less than 2 secs.
In the future, I hope there could also be an option to invert the horizontal or vertical movement of the camera and probably also support PELCO protocol later in its development
Another idea is if keyboard shortcuts can be assign to the command buttons especially with the presets
More power to the developers!
