Frame rate will be constrained when the network bandwidth is narrow.

 

Frame rate will be constrained when there is prolonged network delay or when the data

 

volume sent from VN-E4is high. When this occurs, enlarge the window scale of the PC on

 

which the viewer is running. The window scale can be altered by changing the Windows

 

registry. Refer to Windows manual on procedures to change the Windows registry.

Narrow network bandwidth or considerable jitter may cause failure of smooth transmission.

 

This can be remedied by reducing the transmission volume. Transmission volume can be

 

lowered by reducing the number of channels, frame rate and frame size of JPEG data to

 

acquire.

 

 

 

 

 

 

 

 

Audio output from the PC will pass through Windows’ sample rate conversion function. For
