About 6 months ago I did an upgrade with an old (6 years) 16ch analogue DVR.

We sourced some Hikvision cameras that were all supposed to dual output (CVBS & TVI). When we got them, we realised that although they all had the exact same model number, about half of them didn't have the switch-ability to output both formats. Go figure.

We were told that there were a limited supply of that model (2CE56F7TAVIZ) and that they were being phased out, but they couldn't tell us if the move was being made toward, or away from the dual output with the replacement model.

I don't think I've seen one with dual output since.
