If you would like to control access to your shared USB webcam, you can set a password authorization that will protect the device from unwanted connections.
To be able to share a webcam over the Internet, your local computer, to which the device is connected physically, needs to have an external IP address.
When redirecting some sensitive data to a remote computer it’s recommended to enable traffic encryption. This will protect your data from being intercepted or lost.
It will be a good idea to use the traffic compression option in case you are dealing with limited bandwidth or just want to speed up your communication.
