I've seen recently that ONVIF is rapidly becoming a new standard for camera control functions such as PTZ. Unfortunately, the cameras I need to support right now do not seem to conform to that standard. I'm specifically looking for the source code for a library which can support at a bare minimum the PTZ functions of the following cameras: BB-HCM511 BB-HCM735 BL-C210 BL-C230 If I can't find anything, I'm going to have to hook these up to the network and decode the protocol information to write a library whereas I need to develop an application which can control these cameras. Any guidance from anyone who's done this before would be greatly appreciated. -Robert
