Alright, let me just get this out of the way right off the top: I don't want anyone trying to sell me anything, I don't need anyone telling me how s***ty this camera is, or any recommendations on something different to sell the client on. We've tried to tell him numerous times how... unworthy these things are, but he gets them cheap from China and insists on bringing them in and continually trying to sell them to us. Everyone got that?
Now here's the thing: he's brought in this little beastie that looks like any standard 1/3" camera, but with a built-in zoom lens (spec sheet says it's actually only a 1/4" Sony chip). It does powered zoom (22X,
3.9-85.8mm) and autofocus. I've got the power hooked up and the camera running - image quality is mediocre at best (for what purports to be a "Sony Super HAD CCD"). Autofocus operation is... well, practically useless, I have to fine-tune anything it does manage to lock in on.
Zoom and focus can both be controlled through buttons on the back of the camera, or through wires in the combined remote/power connection (5-pin mini-din). The connector's pins are labeled +12VDC, GND, ZOOM, COM, and FOCUS.
What I'm trying to determine is how to use/connect the external zoom/focus controls via this wire, and hoping someone might have run into one of these things and/or have some documentation for it that's NOT mostly in Chinese. I've tried connecting both ZOOM and FOCUS wires to COM, as well as giving them +12 and GND, with no response at all.
