Thanks JD for your clear, clean and prompt reply. That helps clear a little fog on recording issues. The tip on camera placement was an eye-opener. 
Next question where do I find a genuine Geovision-800 and what do these cost? 
  
I have been geovisioning on EBay. Lots of sellers. Many with doubtful credentials.... copied cards, copied software, doubtful support... 
  
Once again thanks in advance.
