What cameras in the PTZ Optics range can be fully controlled (pan, tilt and zoom) with Chrome (support added in Chrome 87)?
Will this work over the USB connection? Could the camera be controlled from a browser through a web interface over the USB connection?
No, the WEB Gui works strictly using HTTP which is a network protocol, it would never work over USB.
Any of the PTZ style cameras we sell that have a network connection are controllable through their Browser Interfaces.
And most major browsers (Chrome included) will work for accessing the camera's Web Interface.
