DVR with loop-through and REAL-TIME output

[Trailer 0]

Hi,

 

We have been testing a Bosch 600-series DVR. The only thing we are not happy with, is the delay on the VGA outputs.

 

Can anyone suggest DVR's with less delay on the VGA outputs?

 

Our demands for DVR:

• 8 video channels(Composite video, BNC)
  
• Loop-through for all 8 video channels
  
• 1 or 2 VGA outputs(can be splitted, must be close to real-time)

 

We have eight cameras. We need two recorders for redundancy, therefore we need loop-through on all inputs. We need to show the video in real-time on a videowall, therefore we need VGA-outputs.

 

We tried the Bosch 600-series. It has about 200ms latency from picture taken to picture on screen.
