DVR Resolution output confusion

Hi guys,

I am planning to buy a 1080p 30 fps 2 MP dome camera. But i struggling to find an associated DVR that can display the same resolution @ realtime encoding.

My confusion is regarding the Recording resolution and Video Output . This is what is see on the specification page of DVRs for Video output

Quote

Video Output:  1-ch, resolution: 1920 × 1080P / 60 Hz, 1280 × 1024 / 60 Hz, 1280 × 720 / 60 Hz, 1024 × 768 / 60 Hz

Correspondingly i see the following for Recording Resolution or Encoding Resolution (various brands)

HIkVision
Main stream: 1080P(non-real-time) / 720P / VGA / WD1 / 4CIF / CIF  Sub-stream: WD1(non-real-time) / 4CIF(non-real-time) / CIF / QCIF / QVGA
Main stream: 1/16 fps ~ Real time frame rate/ Sub-stream: 1/16 fps ~ Real time frame rate

Another local brand

1-ch, resolution: 1080P/720P/VGA/4CIF/CIF  Main stream: 1/16 fps ~ Real time frame rate / Sub-stream: 1/16 fps ~ Real time frame rate

 

 

So the video output shows 1080p 60 hz (60fps right??) but the recording is 1080 non realtime (12 fps). How will this work?
