Hello, I have a site that has 72 inside fixed cameras on coax and 7 outside PTZ cameras on fiber. All cameras video work fine. The inside fixed are being converted to IP with Sony SNT-v704 video servers. Everything is ran back to 2 rack mounted HP Servers running server 2008 with plenty of storage space. 2 client computers running ONSSI software with 50 inch monitors . My problem is the speed of the network is very slow. The cameras randomly loose connection to the network and start and stop and I loose control of the PTZ cameras. They start to pan and then just keep going. They work fine when in test mode it only happens when I go thru the lan and not all the time. This lan is just for the cctv system there is nothing else on it. This is all new construction with all new cable. The contractor ran the wrong cable for the system (coax). I think my problem is with the switch slowing down the network. I am trying to push video from all 80 cameras through 20 SNT Vt04 servers then to one 24 port switch to the servers. Any help or suggestions as to what would have to be added to this system to make it work properly would be greatly appreciated. Thanks

Thanks for all the quick response. I wish having the contractor repull was an option. We took the the job after the coax was ran our sales person said we could do it with the coax. Then went and purchased all this equipment without getting any design help from anyone. He no longer works for our company but we still have to get it working. We have so many pieces it is amazing we have got as far as we have. Besides the 20 Ipela boxes we have protocol converters for the PTZ cameras Pelco D to Pelco P and fiber converters it is a mess. It looks like a new switch will be the next and hopefully the last piece of this puzzle. Thanks again for all the advice I was about out of Ideas.

The switch is Netvanta model 1234 st 24 Auto-sensing 10/100Base-T ports and Two 10/100/1000Base-T ports. The Sony SNT V704 is 100/10Base-T. The NICs in the servers and clients are gigabit.
