This official 05.39 update from CyberNova is a first step to bring the ONVIF compliance to the WIP604MW, well...sort of...
Before you jump on it, let me moderate your enthusiasm by saying that I could not get the camera to work with Synology Surveillance Station nor Hit-Mob's IP Camera Viewer.I have one of the oldest hardware version of this camera, so maybe this is why my tests failed...
Strangely though, the Onvif device manager does find the camera all right and gets the picture back from it.
