Delay between live and view

[bentech 1]

Hi,

 

Having a system with 2 16 channels NVR connected to a 10/100Mb router.

 

To that router , I have a DVR 30 cam analog and a PC that runs a client software to see some cams pattern .

 

Problem is there is a delay between the live action and the view in patterns .

 

Sometime 30 sec sometimes 2

Minutes.

 

Is the that the bandwidth is not enough ? Is the router 100Mb ok ?

 

Any settings to lower bandwidth of the IP cam ? Or DVR ?
