Thanks for the replies Rory, all the way from the sunny Bahamas...its about 10c here brrrrrrrh.
I have tried most of the cctv dvr programs out there including Luxriot (only does about 5 protocols,Kalatel not one of them unfortunately)
Any idea where I can find out about the Kalatel protocol so I can throw hex commands at the camera via rs232 to rs 485 convertor ?
