Does Flussonic Watcher work with PTZ controls?
Yes, it does.
But there is a thing you should bear in mind. The Flussonic Watcher UI includes PTZ (pan–tilt–zoom) camera controls, but the stability of PTZ operation depends on the particular camera. Many cameras have a poor PTZ/ONVIF implementation. In fact, some camera descriptions may mention PTZ support while it does not work.
