Hi folks really hope somebody can help, i'm on a biggish site which i have installed a 35 camera system. im using a Dahua 64 channel nvr with 16 hardrive slots on the front. currently only has 6 slots in use. the ip cameras are running 2mp and 3mp in various warehouses. there are 2x 24 port gigabit poe switches, 1x 8 port 10/100 poe switch and 1x 24 port 10/100 24 port poe switch with 2 gigabit uplink ports. the issue im having is there are also 2x 32 channel nvrs. we are intergrating in with an IT company for that is already installed. if i plug 1 of the 32 channels in and load the cameras onto it the system works fine, but if i plug the 2nd one in to the system the cameras drop off the system and have periods of not recording. as soon as unplug one of them the system works fine again. i have gone through each camera and looked at the bandwidth used and most of the cameras are set up at: Stream 1 15 FPS, 2000KPS and Variable bit rate and stream 2 15FPS, 2000Kps and variable bit rate.

hi guys im new to this forum, I was wondering if you guy could help me with a problem im having. I have a dahau nvr616-128-4k with 35 ip cameras coming back to it via 3 poe switches in various places When viewing the images on the screen the video is jumping, the camera frames rates are set at 25fbs stream 1 and 15fps stream 2. ive tried just viewing a 4 cameras on the screen and still no different to viewing 32. The network card is showing that its receiving around 85 mbs. Im really stuck on what to try next as my first thought was the frame rates were to low. some cameras are worse than others. many thanks
